Question

After a heat wave, only drought-tolerant individuals were able to survive and produce offspring. This is an example of..

Mutation
Gene flow
Natural selection
Genetic drift

Answer 1

its natural selection C

Step-by-step explanation:

gene flow is when genes from one population move to another. Above answer is wrong. Mutation would be when one individual mutates, but the question states that multiple individuals survived. Do you think that the EXACT same mutation happened in multiple people? I don't think so. Therefore, it must be C.

Answer 2

gene flow

Step-by-step explanation:

i hope this helps-

as what the question says if they could produce offspring and pass the genes on to their kids, mutation could be possible though
