Answer:
a. Only the DNA of β cells contains the gene for insulin; only the DNA of chief cells contains the gene for pepsinogen
Explanation:
As stated in the question above, insulin production is exclusive to β cells in the pancreas. This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.

Answer:
The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of <u>temporal</u> isolation.
Explanation:
Temporal isolation is a form of reproductive isolation in which two or more species reproduce at two separate times.
<u>For example:</u> Northern america leapord frog mates in April and North America Bullfrog mates in july.
As in the given scenario, reproductive isolation is occuring in which two species (Monterey pine and Bishop's pine) are reproducing (producing pollens) at two separate times(February and April). Hence it is an example of temporal isolation.
