Answer 1

The correct answer is 'D'.

Answer 2

## Step 1The problem is asking us to identify which of the given examples can be classified as "struggle to survive" in the context of natural selection. Natural selection is a mechanism of evolution that involves the differential survival and reproduction of individuals due to differences in their traits.## Step 2Let's analyze each option:### A. A family of pigs has a mutation that makes them immune to flu.This is an example of a genetic mutation that provides a survival advantage, but it doesn't directly illustrate the struggle to survive.### B. A family of dogs has a mutation that makes them immune to rabies.Similar to option A, this is an example of a genetic mutation that provides a survival advantage, but it doesn't directly illustrate the struggle to survive.### C. Male rams charge at each other's heads and fight to mate with a female.This is an example of sexual selection, a type of natural selection where individuals with certain traits are more likely to find a mate. While it does involve a struggle, it's not the struggle to survive in the context of environmental pressures.### D. Many species of fish lay millions of eggs at one time, only a few of those survive.This is a classic example of the struggle to survive. In this case, the struggle is for survival among the offspring, as only a small percentage will survive due to environmental pressures.
