what organic molecules are in chicken
Answer:
Organic molecules present in chicken are Nucleic acid, proteins, carbohydrate and lipids .
Explanation:
Chicken itself has the all four organic molecules in it. Organic molecules are those having carbon in it. They are attached by covalent bonds, in which electrons are being shared within the atoms. The nucleic acids are DNA and RNA which helps in the making of the proteins which are found in the various structure and ought to perform various metabolic functions. Proteins are the building block of the amino acids. Lipids found are the fat bodies, burning of lipids gives us energy.
Chicken contains organic molecules such as proteins, lipids, carbohydrates, and nucleic acids, which are essential for various biological functions and nutritional needs. The nutritional value of chicken can vary depending on farming practices, which can alter the balance of these nutrients, like omega-3 fatty acids.
Explanation:The organic molecules found in chicken include a variety of biomolecules essential for life. Some of the primary categories of these organic molecules are proteins, lipids, carbohydrates, and nucleic acids. Proteins in chicken not only serve as a major source of dietary amino acids for building and repairing tissues but also play roles in various biological functions like enzyme and hormone activities.
Chickens are also a source of lipids, which include fats that are important for energy storage and hormonal functions. Carbohydrates present in chicken are generally found in small quantities and include glycogen, which is a stored form of glucose. Nucleic acids, like DNA and RNA, are present in every cell and are responsible for genetic information and protein synthesis.
Furthermore, chickens produce glycosylated proteins, adding the correct sugars to these proteins. Modern farming practices have influenced the nutritional composition of chicken, altering levels of essential nutrients like omega-3 fatty acid. It has been observed that intensively raised chickens now have higher fat content compared to their protein content, with reduced amounts of omega-3 fatty acids compared to chickens raised in the past.

Which best describes a gamma ray?
A.an energy ray with no mass and no charge
B.a positively-charged ray of light and protons
C.a negatively-charged ray of light and electrons
Answer:
C.a negatively-charged ray of light and electrons
Final answer:
A gamma ray is best described as an energy ray with no mass and no charge, and is a type of high-energy electromagnetic radiation.(Option A)
Explanation:
The correct answer to the question 'Which best describes a gamma ray?' is A. an energy ray with no mass and no charge. Gamma rays are a form of electromagnetic radiation, similar to X-rays, but with higher energy. They are represented by the symbol γ, and unlike alpha or beta particles, gamma rays are not particles, but rather high-energy photons. As such, they have no mass and carry no electric charge.
Gamma rays possess tremendous penetration power, capable of passing through several inches of material, like lead, or even the human body, without being absorbed or deflected. Given their lack of ionizing power compared to alpha or beta particles, they have the greatest ability to penetrate matter.
6. Read the statement from a scientific researcher. Many organisms depend on other organisms to live,
such as bacteria that live inside cells, and fungi that form parasitic relationships. These organisms are
reliant on their hosts to complete their life cycles. Viruses also rely on host cells in a similar manner.
Which argument about viruses is supported by the researcher's statement?
(a) Viruses create new host cells.
(b) Viruses respond to their environments.
(c) Viruses are nonliving.
(d) Viruses are living.
the argument that the researcher supports in this statement is that the Viruses are nonliving
Answer : Option C
Explanation:
Viruses are organic structures and they are often termed as "organisms at the end of life". Virus is not considered a living as it does not have a biological machinery to replicate.It is a parasite and it needs a host to replicate.
The virus tries its entry through the wounds, respiratory tracts and by passing through insects.
The complete virus particle is known as virion which consists of a nucleic acid surrounded by a capsid, Virus first attach themselves to a host through their surface.
explain the types of acid deposition
Answer:
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.
Explanation:
The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.

Why does a cell need to make RNA
Answer:
When the cell needs to produce a certain protein, it activates the protein's gene–the portion of DNA that codes for that protein–and produces multiple copies of that piece of DNA in the form of messenger RNA, or mRNA. ... We now know that RNA can also act as enzymes (called ribozymes) to speed chemical reactions.

ATP molecules, which are used for energy by cells, are built during all three stages of cellular respiration.
Which stage of cellula
respiration generates the most ATP molecules?
A.The Krebs cycle
B.Glycolysis
C.The electron transport chain
D.Fermentation
Answer:
The answer is C. The electron transport chain
Explanation:
Glycolysis involves the conversion of one glucose molecule into 2 molecules of pyruvate with the production of 2 ATPs and 2 molecules of NADH2. The molecules of NADH are used in the electron transport chain to produce more ATPs.The Kreb's cycle produces 2 ATP, 8 NADH and 2 FADH2.The electron transport chain converts 10 NADH and 2 FADH2 to produce 34 ATPs and 2 GTPs to yield another 2 ATPs.In total, one molecule of glucose yields 36 ATP molecules upon respiration.* Each NADH yields a total of 3 ATP molecules whereas each FADH2 yields 2 ATPs.

If the concentration of hydrogen ions (H+) outside of the thylakoids were equal to the concentration of H+ inside the thylakoids, how would it affect the chloroplasts?
The chloroplasts would release excess O2.
The chloroplasts would be unable to generate ATP.
The chloroplasts would make more glucose molecules.
The chloroplasts would make more NADPH than usual.
The chloroplasts would be unable to generate ATP
If the concentration of hydrogen ions (H+) outside of the thylakoids were equal to the concentration of H+ inside the thylakoids, the chloroplasts would be unable to generate ATP
Explanation:
As the high-energy electron from the reactive center of the photosystem conveyed from one protein to another in the protein transport chain of the chloroplast, the energy harnessed from the electron is used to pump H+ ions into the thylakoid lumen against concentration gradient.
The proton motive force created by having a high concentration of H+ ion in the thylakoid lumen than outside is to enable the creation of potential energy that is tapped by ATP synthase to create ATPs in a process called photophosphorylation. The ATPs made in this light stage is used in the anabolic process of the dark stage to make glucose through the reduction of CO2

Why is a dichotomous key called a dichotomous key?
Answer:
The name comes from the Greek “di” for “two” and “tome” for “cutting instrument.” As the name suggests, a dichotomous key arrives at the answer to species identification by presenting a series of questions with two possible answers.
Explanation:
You will understand better with the picture.
A dichotomous key is called so because it presents a series of two opposite choices (dichotomies) at each step to classify and identify organisms.
A dichotomous key is a systematic tool used by biologists and taxonomists to identify and classify organisms based on their observable characteristics. It is designed as a series of paired statements or questions, where each pair represents two opposite characteristics of the organisms being studied. The user must choose the statement that best matches the observed characteristics of the specimen they are trying to identify.
At each step of the key, the user makes a choice between the two options, leading them to the next set of characteristics that narrows down the possibilities. This process continues until the user reaches a specific name or classification for the organism.
The term "dichotomous" comes from the Greek word "dichotomia," which means division into two parts. The key's structure of presenting two opposing choices at each step helps to simplify the identification process and efficiently categorize organisms into specific groups based on their shared characteristics.
Dichotomous keys are widely used in various scientific fields, including biology, botany, zoology, and ecology, to identify and classify organisms in a structured and organized manner. They are valuable tools for researchers, students, and anyone involved in the study of living organisms.
