Answer:
The shape of a molecule is important because it is a feature that often determines the fate of a compound regarding molecular interactions.
Explanation:
Answer: option D.
Phenotype
Explanation:
Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.
Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.
Answer:
Stomata opens to intake carbon dioxide in the presence of light there by allowing the process of photosynthesis during the day time.
Explanation:
The gaurd cell of the stomata play an important role in regulating the photosynthesis. During the day time, the stomata is open which allows intake of carbon dioxide from atmosphere. Carbon dioxide is very essential for the process of photosynthesis. Thus, during day time when stomata is open photosynthesis takes place while during night time when stomata is closed photosynthesis do not occur. Also the stomata regulate the loss of water from the leaves thereby ensuring availability of sufficient water molecules at the time of photosynthesis.
