IT'S JUST A QUESTIONNAIRE ;)

What do you know about adaptation by natural selection?

When there is variability in a population: *

The population has more chances to become extinct because it is not possible for them to adapt to change.

The population cannot face all the environmental challenges.

Variation among individuals is a fundamental requirement for evolutionary change.

I don't know.

The effect of a mutation: *

Is always beneficial (good).

Is always deleterious (bad).

Depends on the environment.

I don't know.

If the environment is not stable (an environment with viruses or a cold environment): *

If there is no variability, the population will become extinct.

If the variants (eye color) do not affect survival, none of the mutations in the population will confer resistance to viruses or cold, and therefore the population will become extinct.

If the changes are not heritable the population will become extinct.

All of the above are correct.

I don't know.

For natural selection to act: *

There must be variability among traits in a population.

Variants must be heritable.

Variants must affect survival

All of the above are correct

I don't know
