Which of the following statements about seafloor spreading is false?
A. Continents move as the seafloor spreads along a mid-ocean ridge.
B. The oldest crust is closest to the mid-ocean ridge.
C. Magma rises through the mid-ocean ridge, forming basalt.
B. The oldest crust is closest to the mid-ocean ridge.
Explanation;Seafloor spreading refers to the process by which new oceanic crust forms along a mid-ocean ridge and older oceanic crust moves away from the ridge. Seafloor spreading occurs at the mid-oceanic ridge where the divergent boundaries cause two plates to move away from each other resulting to the spreading of the sea floor.As the divergent plates move apart, new materials wells up and then cools at the edge of the plates. Seafloor spreading is important as it helps explain the continental drift in support of the theory of plate tectonics.There are many methods used to obtain energy for use in our daily lives. Some of these methods have possible environmental consequences to rivers, groundwater, and organisms. One type of pollution involves excess carbon dioxide being released into the air. Some of the carbon dioxide reacts with water to form acid rain. Which energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere?
Answer: Coal,petroleum
Explanation:
he process that we call "burning" actually is chemical reactions with oxygen in the air. For the most part, the carbon combines with oxygen to form carbon dioxide (CO2), and the hydrogen combines with oxygen to form water vapor (H20).
Some of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.
What is the significance of burning fossil fuels?Carbon dioxide, which is also considered a "greenhouse gas," and other greenhouse gases in the atmosphere trap heat from the sun but never let the heat pass through the earth's atmosphere and make the earth hot. This is caused by the combustion of fossil fuels and causes air pollution, which can be harmful to human health and the earth.
Hence, some of the carbon dioxide reacts with water to form acid rain, and the energy sources can release carbon dioxide and carbon monoxide waste into the atmosphere through the burning of fossil fuels, coal, oil, etc.

The body tissue that connects the muscle to the bone is called
Answer:
The answer is: Tendons.
Explanation:
Tendons are fibrous connective tissue that joins muscles to bones. They can also attach muscles to structures such as the eyeball. Tendons serve to move the bone or structure, while the ligaments are the fibrous connective tissue that joins the bones together and generally their function is to join structures and keep them stable.
The answer is: Tendons.

Select the FALSE statement below about the structure of myoglobin.
a. The O2-binding pocket of myoglobin contains several nonpolar amino acid sidechains that can interact favorably with a nonpolar molecule of O2.
b. The polypeptide of myoglobin provides a pocket for O2 to fit, and stabilizes the bound O2 via hydrogen bonding with the distal His.
c. The polypeptide of myoglobin protects the heme iron from oxidation.
d. The active site of deoxy myoglobin is 5-coordinate with a histidine occupying one axial position while the other axial position is left open for oxygen binding.
e. Myoglobin has a single polypeptide chain so it has 1o, 2o, 3o and 4o structure.

Which of the following contain the genetic code?
1)carbohydrates
2)lipids
3)nucleic acids
4)proteins
Nucleic acids are the carriers of the genetic code. The molecules that carry and transmit genetic information in living things are called nucleic acids, specifically the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) families. Therefore, the correct option is C.
The fundamental genetic material, DNA, is located in the nucleus of cells, while RNA is involved in gene expression and protein synthesis. Sequences of nucleotides, the constituent parts of nucleic acids, contain the genetic code. Proteins, lipids, and carbohydrates all play important roles in many cellular processes and functions within an organism, but none of them directly contain the genetic code.
Therefore, the correct option is C.

What is the main source of energy that drives the water cycle?
The sun is the primary source of energy that drives the water cycle. It provides the heat necessary for evaporation, the initial phase of the water cycle, and influences all subsequent stages of the cycle including condensation, precipitation, and surface runoff.
Explanation:The main source of energy that drives the water cycle is the Sun. The sun's energy warms the oceans and other surface waters, which leads to the evaporation or sublimation of liquid or frozen water into the atmosphere. This water vapor then condenses into clouds, leading to precipitation that brings the water back to Earth's surface again, completing the water cycle.
Evaporation and sublimation are critical first steps in the water cycle. These processes involve the transformation of liquid water or ice into water vapor due to the Sun’s heat.
The water, now in a gaseous state, ascends into the atmosphere where it eventually condenses to form clouds due to lower temperatures at higher altitudes. This is referred to as condensation and it's often followed by precipitation, the process where water is returned to the Earth’s surface as rain, sleet, hail, or snow.
Upon reaching the surface, the water can take several paths. It can flow on the surface, leading to surface runoff, or it can seep into the soil contributing to subsurface water flow. Some of the water ends up in rivers and streams, referred to as streamflow, and eventually makes its way back to the ocean again, completing the cycle.
