Question 25

Question

Read the passage about newts.


A certain species of newt can produce a toxin that can kill predators. Scientists have observed that some snakes can eat the newts because they have a natural resistance to the toxin.

In areas where newts and snakes interact, which of the following explanations is best supported by the theory of evolution?

a
The snakes acquired the resistance through learning.
b
The snakes acquired the resistance due to genetic drift.
c
The snakes with the resistance to the newt toxin will pass on the gene for resistance to their offspring.
d
The snakes with the resistance to the newt toxin have a gene mutation that will not be passed to their offspring.

Answer 1

c
The snakes with the resistance to the newt toxin will pass on the gene for resistance to their offspring.
