The correct answer is option B, that is, increased availability of food.
The carrying capacity of a biological species in surrounding refers to the majority of the size of the population of the species, which the environment can maintain indeterminately, given the habitat, food, water, and other essential necessities in the environment.
In terms of population biology, carrying capacity is illustrated as the maximum load that can be handled by the environment. Thus, in the given case, the carrying capacity of the prairie dogs in an area gets increased with the increase in the availability of food.
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.
If we cross a homozygous blue oval plant with a homozygous white round plant
P: BBrr x bbRR
The resulting F1 progeny:
F1: BbRr
If we cross BbRr with bbrr
F2: 1/4 blue round plants (250 plants) ¼ blue oval plants (250 plants) ¼ white round plants (250 plants) and ¼ white oval plants (250 plants).
