aalyn [17]

Answer:

C. Beak size is an inherited trait in the finch population under study.

D. Birds that could eat larger, tougher seeds survived and reproduced during the drought.

E. Beak size varies among the birds in the finch population under study.

Explanation:

The presence of genetic variations among the individuals of a population is required for natural selection to be operative. Natural selection targets the beneficial genetic variations present in the population. Natural selection refers to the differential reproductive and survival success of organisms of a population due to some beneficial genetic traits. These organisms with beneficial genetic traits are able to survive and leave more progeny under prevailing conditions.

If the natural selection has occurred in the ground finch population for the beak size, the beak size should be a genetic trait since natural selection works on genetic traits only. The finch population should have variations with respect to the beak size. The finches having the larger beak size that enabled them to feed on larger, tougher seeds should have higher survival and reproductive fitness during the drought.

Under these conditions, natural selection would favor the finches with larger beak size and would eventually result in an increase in the average beak size of the future generations.

Anna71 [15]

From the table, we can see that  P and Q represent water. (Option B)

<h3>What does P and Q represent?</h3>

We know that the liquid range of water is 0 - 100 degrees Celsius. Within this temperature range, water exists as a liquid substance.

Looking at the table we can see that the temperatures of P and Q are 50 and 100 degrees Celsius respectively hence both P and Q represent water.
