The shells of some marine snails are highly variable, with some snail shells being solid and others having stripes. predation by birds is a major source of mortality for the snails. scientists studying these snails found that while 47 percent of the snail population was striped, 56 percent of the snails eaten by birds were striped. what could scientists conclude about the snails?

Birds have preference to striped snails

Explanation:

The total number of snail with stripes is lesser in number as compared to the total number of snails with solid or no color. Despite this, the birds prefer to feed on snail species that are in minority to the total snail population.  

This represents likeliness of birds to feed on striped snails which constitutes nearly 56 percent.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
