what physical health risks are directly associated with urban sprawl?
Answer:
The risks of various pollution and infections increase with urban sprawl.
Urban sprawl can be described as a condition in which the people from urban area migrate to low residential areas due to which the city starts to expand more in size.
During urban sprawl, more water contamination is likely to be caused as the water available cannot support such a large number of migration. There is not proper sewage system due to which contamination arise and cause sickness in the people. Also, these areas have more pollution due to traffic jam situations which causes sickness.
Answer:
The physical health risks that are directly associated with urban sprawl is pollution and infections. During an urban sprawl, there are increased chances of water pollution and poor drainage system which can ultimately affect a population because the water can release toxins into one's body, which can cause diseases and illnesses. The respiratory system will get affected because when there is a population increase, the amount of air pollutants release would increase giving chances to lung cancer and breathing problems.
Which of the following chemical structures can form hydrogen bonds with water? Methane (CH4), molecular oxygen (O2), hydrogen sulfide. explain
Answer: Molecular Oxygen (O2) and Hydrogen Sulfide.
Explanation:
A hydrogen bond is defined as the electrostatic attraction between an electrically negative atom and a hydrogen atom attached by a covalent bond to another electronegative atom. This bond is strong due to the number of atoms that bind, but weaker than a covalent bond or an ionic bond.
The atoms with the most significant negative electrical force are oxygen, fluorine, and nitrogen.
An example of a chemical structure formed by a hydrogen bond is water. The water is formed by two hydrogen atoms and one oxygen atom. Due to the majority of hydrogen atoms present in the water structure, it is possible to join other molecular structures such as fluorine.
I hope this information can help you.
Hydrogen sulfide can potentially form weak hydrogen bonds with water due to the presence of hydrogen atoms bonded to an electronegative sulfur atom, whereas methane and molecular oxygen cannot participate in hydrogen bonding with water.
Explanation:A hydrogen bond is a type of intermolecular force that occurs when a hydrogen atom, covalently attached to a highly electronegative atom such as nitrogen (N) or oxygen (O), is attracted to a lone pair of electrons on another electronegative atom in a neighboring molecule. Among the substances listed (methane (CH4), molecular oxygen (O2), and hydrogen sulfide), hydrogen sulfide has the potential to form hydrogen bonds with water because it contains hydrogen atoms directly bonded to an electronegative sulfur atom. Methane, on the other hand, consists of hydrogen atoms bonded to carbon, which is not sufficiently electronegative to create hydrogen bonds. Molecular oxygen does not have hydrogen atoms and thus cannot participate in hydrogen bonding as a hydrogen bond donor. However, it is important to note that hydrogen sulfide's hydrogen bonding is much weaker compared to that of water due to the lower electronegativity of sulfur compared to oxygen. This affects the degree to which hydrogen sulfide can form hydrogen bonds with water.

Submit
Human Population Growth
Answer:
The correct answer is : sustainable use
Explanation:
Sustainable use: The judicious and economical use of natural resources by the present generation such that the resources can be preserved for use by the successive generations is known as the Sustainable Use of Resources.Resource Selection : When a species selects a specific resource as the source of food or energy or shelter from among multiple available sources, the phenomenon is called Resource Selection.Biotic preservation : The protection of biotic organisms (plants, animals, micro-organisms) by in-situ ( in the habitat of the species) or ex-situ (outside the habitat of the species) conservation in national parks, sanctuaries and biosphere reserves to prevent them from becoming endangered or extinct due to natural disaster or human intervention.Biogeochemial cycling : The nutrient cycles operating on the earth, like nitrogen, carbon, oxygen, sulphur, phosphorus and water cycles, and their interaction with each other and the organisms living on earth constitute the Biogeochemical cycle.Use symbols to distinguish between parasitism, mutualism and commensalism.
Parasitism, mutualism, and commensalism are types of symbiotic relationships and can be represented by '+/-', '+/+', and '+/0' respectively, indicating the effect of the relationship on each organism.
Explanation:The forms of symbiotic relationships, including parasitism, mutualism, and commensalism can be distinguished by the effect they have on the organisms involved. Parasitism can be symbolized with a '+' for the parasite and a '-' for the host, indicating that the relationship is beneficial for the parasite but harmful to the host. Mutualism can be represented by a pair of '+', or '+/+', indicating that both organisms benefit. Commensalism could be shown by '+/0', meaning one organism benefits and the other is neither helped nor harmed in the relationship.

Parasitism is a symbiotic relationship where the parasite benefits at the expense of the host. Mutualism is a symbiotic relationship where both organisms benefit. Commensalism is a symbiotic relationship where one organism benefits, and the other is neither harmed nor benefited.
Explanation:In biology, parasitism, mutualism, and commensalism are three types of symbiotic relationships that describe interactions between two organisms where at least one organism benefits.
Parasitism (+/- interaction): This refers to a relationship in which one organism, the parasite, benefits while the other, the host, is harmed. An example of this is a tapeworm living in a human's intestines. Mutualism (+/+ interaction): This is a symbiotic relationship in which both species benefit. An example of this is humans and gut bacteria, where bacteria digest food and produce vitamins that humans can't, and in return, the bacteria get a safe and nutrient-rich environment. Commensalism (+/0 interaction): This means one organism benefits while the other is neither harmed nor benefited. An example is a bird building a nest in a tree; the bird gets a place to live, but the tree is unaffected. Learn more about Symbiotic Relationships

Modeling the Calvin Cycle Exploration
1. Glucose, a six-carbon chain, results from the output of the Calvin cycle. Did your exercise generate a glucose molecule?
2. When is glucose generated?
3. What is the chemical formula for photosynthesis?
4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer.
Explanation:
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Further Explanation:
Photosynthesis is a chemical pathway, integral to plant and other primary producers producing energy. Energy is produced from light, water and carbon dioxide in the form of glucose molecules while the oxygen is emitted.
Photosynthesis, which occurs in several complex steps, is a rate-limited reaction, depends on several factors including concentration of carbon dioxide, ambient temperature, and light intensity; energy is recovered from photons, i.e. light particles, and water is used as a reducer. For those removed from photosystem II, water supplies the chlorophyll in plant cell with replacement electrons.
Therefore, water (H2O) split into H+ a by light during photolysis into H+ and OH-acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage moleciule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These hold energy in their bonds, which can be released in respiration in the mitochondria.
Glucose production occurs after G3P production- a molecule of G3P, goes to the cytoplasm from the cycle, to form complex molecules and simple sugars like glucose.

The combination of dominant tree species in Eastern forests will likely change in the future. Some forest types,
including spruce/fir and maple/beech/birch, may shrink significantly or disappear altogether, depending on how
greatly carbon dioxide emissions increase in the future. How would you adapt your behavior to create a different
scenario, one in which the was no substantial change in the tree species over time? Select the tactic that would be of
NO help.
A) Increase your demand for green products and services to reduce your
carbon footprint.
B)Consider alternate energy resources that are not carbon-based: solar or
wind energy
C)Eat locally-produced and organic food; cur meat and dairy consumption.
D)Manage lands for restoration and watershed conservation
Answer:
C) Eat locally-produced and organic food; cur meat and dairy consumption.
Explanation:
Eating organic food will be of no help because humans do not usually use forest trees as food resources. And hence, it will be of no help to stop the carbon dioxide emissions. Hence, option C will be of no help.
The consumption of green products will lead to lesser production of carbon dioxide and hence can be helpful. Using alternate energy sources which are not carbon based will also help to reduce the amount of carbon dioxide. If lands are restored then, these trees will not change over time. Hence, option A, B and D are helpful for no substantial change in the tree species over time.
Answer:
The answer is Not C It is D. I just had the test.
Explanation: Answer C While this is also a positive action, it is not an action that would result in a decrease of carbon emissions. So It is answer D.

Science study the life cycle of pathogens in order to find a way to interrupt the course of disease and spread of infection. Scientist study the life cycle of microorganism in order to find a way to cancer and other chronic illness.
Explanation:
The life cycle of microorganisms causing disease in the human is studied to know what agents or antibiotics would stop their activity. There are techniques used such as chemotherapy to kill the invading viruses. The antibiotics are made this way to stop bacterial growth. The agents would be invented to put stop at the particular phase of the life cycle to inhibit growth of the pathogen. It would get convenient to make agents if at immune level it is known what phase of their cycle is reactive.
Studying the life cycle of microorganisms is important in modern medicine to find ways to interrupt the course of disease and prevent the spread of infection.
Explanation:Studying the life cycle of microorganisms is directly related to modern medicine because it helps scientists understand how pathogens cause disease and how to interrupt their course of infection. By studying the life cycle of microorganisms, scientists can find ways to treat chronic illnesses and develop strategies to prevent the spread of diseases. For example, understanding the life cycle of cancer cells can lead to the development of targeted treatments. Therefore, option d, 'Scientists study the life cycle of microorganisms in order to find a way to interrupt the course of disease and the spread of infection,' is the correct answer.

A reflex action is an involuntary response to a stimulus, exemplified by jеrking the hand away from a hot surface, and occurs via a reflex arc in the nervous system.
The concept of reflex action is fundamental in biology when discussing the nervous system and its responses to stimuli. A reflex action is an involuntary and nearly instantaneous movement that occurs in response to a stimulus. Unlike voluntary actions, which are under the conscious control of the mind, reflex actions happen automatically, without the need for conscious thought. An example of a reflex action can be the jеrking away of the hand from a hot surface. This action is because the external stimulus (the heat from the hot surface) starts impulses in neurons at the body's surface, prompting an immediate response.
Reflex actions are carried out through a reflex arc, consisting of sensory neurons, interneurons, and motor neurons. When a stimulus is strong enough, it triggers sensory neurons, which pass the information via interneurons to motor neurons, resulting in a reflex movement. This process happens very rapidly and does not involve the brain.

Which describes a population depending on an abiotic factor?
Answer:
Hello!
I'm assuming the options are:
A) A bean plant does not grow well because it is planted where there are many weedy plants.
B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.
C) Squirrels eat eggs from a bird's nest.
D) A hawk preys on a mouse.
The answer is B) Coral reef organisms carry out photosynthesis using the sunlight that passes through the clear water above.
Explanation:
An abiotic factor is a non-living factor of an ecosystem that influences the biotic factors and the population inhabiting that ecosystem.Option A describes competition between two plants. This is an example of a relationship between two biotic factors (bean plant and weeds)C again describes the food relationship between two biotic factors (squirrel and bird's eggs).D is an example of predator-prey relationship which is also an example of two biotic factors influencing each other. B describes how coral reefs (biotic factor) utilizes sunlight (abiotic factor) to produce food and and oxygen through photosynthesis.Abiotic factors such as sunlight, rainfall, and temperature affect populations. Organisms have a range of tolerance for abiotic factors, and some species act as indicator species for specific factors.
Explanation:Abiotic factors are the physical and chemical characteristics of the environment that affect populations. For example, the amount of sunlight, rainfall, available nutrients, oxygen levels, and temperature are all abiotic factors. These factors determine the success of populations and can influence the types of organisms that can live in a particular area. For instance, the amount of annual rainfall can determine whether a region is a grassland or forest, which in turn affects the types of animals living there.
Abiotic limiting factors can have a range of tolerance for a population. A species may have a narrow tolerance range for a specific abiotic factor. For instance, a freshwater fish species may have a narrow tolerance range for dissolved oxygen in the water. If the dissolved oxygen level decreases due to eutrophication, the species will die. This fish species can act as an indicator species, as its presence or absence indicates the dissolved oxygen content of the lake.

List 4 things humans and primates have in common.
Answer:
A. Opposable thumbs
B. Depth perception
C. Maternal care
D. Large brains
Explanation:
Opposable thumbs --> Primates have opposable thumbs and refined hand and foot development . An opposable thumb is able to be moved opposite the fingers of the same hand in order to better grasp objects. This is an adaption for an arboreal, or tree-dwelling, lifestyle because it helps the primates have strong grips on the branches. Raccoons, dogs, and other non-primate mammals do not have opposable thumbs. This means they cannot move the thumb opposite the fingers of the same hand to grasp things tightly. This is why your dog would have trouble holding and manipulating a small object like a door key with his paws.
Depth perception --> Primates have an increased reliance on sight and decreased reliance on smell, compared to other mammals. The eyes are large and forward facing, which provides better depth perception. The nostrils are smaller in relation to the face than in many other mammals.
Maternal care --> Primates have a smaller litter size, longer gestation, and extended period of juvenile growth compared to other mammals. Most primates have one or two offspring at a time. They also exhibit increased periods of maternal care for their young compared to that of other animals.
Large brains --> Primates have relatively large brains. Primates have larger brains, relative to their body size, than most other mammals.

What types of materials are expelled from cells during exocytosis?
Question 8 options:
large molecules such as hormones
positive and negative ions
small molecules such as carbon dioxide
water and glycerol
"Large molecules such as hormones" types of materials are expelled from cells during exocytosis.
Answer: Option A
Explanation:
The mechanism whereby a cell transfers secretory products to the plasma membrane via the cytoplasm is termed as "exocytosis" while material passage into the cell is known as "endocytosis". Exocytosis is need for removing waste material from cell.
In exocytosis, mechanism huge quantity of molecules which means bulk transport is performed.Responsible for secretion of digestive enzymes and hormones. In this process, membranes-bound secretory vesicle pass to the cell membranes while their material like water-soluble molecule get secreted in the extracellular atmosphere.
Macromolecules are made of subunits called monomers. What are the monomers of protein called?
Answer: Amino acid
Explanation: proteins are made up of amino acids or we can also say that amino acids are the building block of proteins molecules. Amino acids are the basic subunit of the protein. Different Amino Acid joins and forms large molecules called polymers of protein.
The monomers of proteins are called amino acids, each consisting of an amino group, a carboxyl group, and a side chain.
Amino acids are organic compounds made up of four key components: an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a side chain or R-group, which is unique to each amino acid.
The amino and carboxyl groups are crucial functional groups that define an amino acid's chemical properties and behavior.
There are 20 standard amino acids that serve as the building blocks for protein synthesis.
The variations in the R-group give each amino acid its distinct characteristics, including size, shape, charge, and chemical properties.
Amino acids link together through peptide bonds, forming linear chains called polypeptides.
When a peptide bond forms, a molecule of water is released in a condensation reaction. This repetitive bonding pattern forms the primary structure of a protein.
The sequence of amino acids in a protein chain is determined by the genetic information encoded in DNA.
Proteins exhibit a hierarchical structure, including primary, secondary, tertiary, and quaternary structures, which result from the interactions and folding of the polypeptide chains.
The specific sequence and arrangement of amino acids dictate a protein's final three-dimensional shape and function.

. An unsound spine
Problem: Our spines are a mess. It’s a wonder we can even walk, says Bruce Latimer, director of the Center for Human Origins at Case Western Reserve University, in Cleveland. When our ancestors walked on all fours, their spines arched, like a bow, to withstand the weight of the organs suspended below. But then we stood up. That threw the system out of whack by 90 degrees, and the spine was forced to become a column. Next, to allow for bipedalism, it curved forward at the lower back. And to keep the head in balance—so that we didn’t all walk around as if doing the limbo—the upper spine curved in the opposite direction. This change put tremendous pressure on the lower vertebrae, sticking about 80 percent of adults, according to one estimate, with lower back pain.
