Answer:
A) maximizes light absorption by the chloroplasts for photosynthesis
Explanation:
Chloroplasts are the double membrane-bound organelles present in the leaf cells. Chloroplasts contain light-absorbing pigment chlorophyll that absorbs maximum light of blue and red wavelengths.
Absorption of light by chlorophyll pigments drives the light reactions of photosynthesis which in turn provide ATP and NADPH to fix carbon dioxide gas into glucose by light-independent reactions. The process of photosynthesis produces glucose which in turn serves as an energy source for plants and supports their growth and development.
Therefore, exposure to blue light increases the rate of photosynthesis as chloroplasts in the leaf cells are aligned to absorb maximum blue light to support photosynthesis. And a higher rate of photosynthesis produces more glucose to support the growth of the plants.
Answer: double helix
Explanation: The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
Answer:
1 and 3
Explanation:
Magnetic waves always go from north to south. So judging by the arrows you can tell the left/yellow pole is the north one. And since that is the north one, the green/right one is the south pole.
