What is a disadvantage of having too much variation in a population?
It can lead to more diseases.
It can make it harder to adapt to a specific environment.
It can cause the population to grow too fast.
It can make individuals look too similar.
How can variations help a population survive a sudden change in the environment?
By making all individuals identical.
Providing different traits might be beneficial.
By reducing the number of individuals.
By making the environment change back.

What is one advantage of having variations in a population living in a diverse environment?

It makes the population more vulnerable to predators.
It causes the population to become extinct.
It reduces the population's ability to reproduce.
In a desert environment, which variation might be beneficial for a population of animals?
