Answer:
Atmosphere refers to the thin blanket of air that surrounds the earth.
It serves many important functions such as:
- It contains a mixture of gases that are essential for the existence of life on earth. For example, carbon dioxide is essential for photosynthesis and oxygen is essential for cellular respiration.
- It also serves as the reservoir of water in the form of water vapor. Thus, it forms an important constituent for the water cycle.
- It maintains the temperature of the earth. Through the greenhouse effect, it maintains the temperature of the earth in limited ranges.
- It protects the earth from harmful rays of the sun. For example, ozone inhibits the entry of most of the UV rays of the sun into the earth environment.
Semen is the correct answer
A. The process of photosynthesis is energy-storing because the process converts light energy into chemical energy, which is stored in the bonds of glucose.
Answer:
Uranus
Uranus' axis is tilted, so it rotates from top to bottom.
Answer:
The third stage in the synthesis of fatty acids is the synthesis of palmitic acid (letter e)
Explanation:
The synthesis of fatty acids takes place in the cytoplasm of the cell. The first step is the transport of acetyl-CoA to the cytoplasm. This came in the form of citrate usually from the pyruvate generated in the glycolysis from the mitochondria. The citrate is enzymatically transformed into acetyl-CoA.
Once the acetyl-CoA is in the cytoplasm, this is transformed into malonyl-CoA. This molecule will be the donor of two carbons in the synthesis of fatty acids.
In the final step takes place a cyclic process of reactions (condensation, reduction, hydration and second reduction) to synthesize the palmitic acid ( 16 carbons) by the fatty acid synthase.
