a) Natural selection will work negatively against rabbits that only eat berries as the drought is preventing berries from growing. It wont have any negative impact on rabbits that only eat grass as the grass is still surviving.
b) The statement ‘population has variations’ is backed up by the fact that the rabbits eat different things. They aren’t all the same. The statement ‘some variations are favorable’ is backed up by the fact that the rabbits that only eat grass are able to survive the drought. Their variation in eating grass instead of berries let’s them live. The statement ‘a population will change over time’ is backed up by the fact that the rabbits that only eat berries will die out. This will not only change the size of the population but going forward will create a population that has more rabbits that eat only grass on account of natural selection.

Answer: A. convergent
Most earthquakes occur at the boundary where two plates meet. This phenomena is called as convergent plate tectonics. In this phenomena the two plates moves towards each other. If the plates are of equal density then they will push each other but if they are of unequal density, the denser plate sink beneath the other plate.

A)
Explanation:
It estimates the probability of extinction.
Answer:
The volume of sample at STP is = 41.22 ml
Explanation:
Given data
= 0.9 atm
= 50 ml
= 298 K
At STP
= 1 atm
= 273 K
From ideal gas equation


= 41.22 ml
Therefore the volume of sample at STP is = 41.22 ml
