Answer:
Leave is an important structure of plant body where food production occurs in the process of photosynthesis. In the leaves, small tiny pores called stomata are present on lower side of the leaf. These pores are responsible for the exchange of gases such as carbondioxide and oxygen. These stomata opens and carbondioxide is absorbed from the atmosphere and water from the soil. Both reactants combine in the presence of sunlight producing oxygen and glucose. Oxygen is released through stomata and glucose is stored in different parts of plant.
Answer:
The correct answer is - option A. differential reproductive success based on inherited traits
Explanation:
Natural selection is the differential reproductive and survival of particular population due to the difference of shared characteristics that are inherited in a specific environment. In other words natural selection is differential reproductive success based on inherited traits.
The term differential reproductive success is suggests that comparing and analyzing successful reproduction rates between groups statistically which means how many individuals of the population left behind due to not inheriting traits require for survival.
Thus, the correct answer is - option A. differential reproductive success based on inherited traits
Answer:
NVM Just report this answer.
Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct
