Complete question: What situation might develop in a population having some plants whose flowers open at midday and other plants whose flowers open late in the day?
a. Temporal isolation
b. Geographic isolation
c. Behavioral isolation
d. Genetic drift
Answer:
a. Temporal isolation
Explanation:
Temporal isolation is one of several mechanisms of reproductive isolation. Temporal isolation occurs when some organisms of a population exhibit different timing of reproductive maturity. It also occurs when some members of a population reproduce at a different time from the others. This does not allow interbreeding between them.
When plants of a population open flower at a different time of day, cross-pollination would not occur between these plants. This represents temporal isolation.
This answer is B because it is not made up of cells, the easiest way to know this is because viruses are much smaller than a single cell, meaning its impossible for it to have cells or be a living organism.
Answer: Option A.
To catalyze chemical reactions
Explanation:
Enzymes are substances or biological catalysts that speed up and drive chemical reactions in the cells.
Without enzymes life will not exist because enzymes are present in most cells and help to perform complex tasks the cells cannot do on their own.
Enzymes perform functions in digestive system by breaking complex food in to simpler form which the body can absorb.
Enzymes help also in metabolism. Enzymes catalyse chemical reactions.
