Sea gulls prey on snails on the rocky sea coast. the snails vary in color from solid brown to brown and tan striped. the birds suck the soft snail bodies out of the shells and leave the shells behind on the rocks. scientists picked up 500 empty shells and found that 400 of the shells were solid brown and only 100 were striped. over the years, what would you expect to happen to the snail population?
a. the snails would become extinct.
b. there would be mostly brown snails.
c. there would be mostly striped snails.
d. there would be an even number of brown snails and striped snails.

C. There would be mostly striped snails

Explanation:

If scientists find that the sea gulls continue eating most of the brown shells, it would be expected that the pressure over this population would be higher than over the stripped shells.

What would happen then is that the brown sea shells will reduce its population and the stripped will increase in population or maintain the same (unless they have some other predator).

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
