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.
C The dark green phenotype benefits the insects' survival, making them more likely to reproduce.
If sodium ions are outside of a cell, they will tend to move into the cell based on both their concentration gradient and the voltage across the membrane (the more negative charge on the inside of the membrane). So cells pump out the extra ions.
