Migration is an example of this mechanism of evolution.

These drugs are used to treat bacterial infections.

Viruses are considered to be....

The idea that better adapted individuals will survive, reproduce, and pass their traits on to their offspring

This is when long periods of stability are followed by short periods of rapid growth.

These are random changes in DNA that result in new traits.

This is what happens when bacteria are no longer affected by antibiotics. This is called....

Viruses can reproduce without a host. This is why they are so deadly. (True or false)

Adaptations are a result of these changes in genetic material

This is when organisms continually gradually evolve over time.

This is what happens after natural disasters, where only a small part of the population survives and reproduces.

This is what causes antibiotic resistance.

In order to treat viral infections, we should not use...

When a trait is "selected for" this means that the adaptation is....

This is when one parent species evolves into two new species.

When a part of a population becomes isolated and only a small part of the population starts a new population. This type of genetic drift is called....

A pesticide is sprayed on orange trees to kill fruit flies. Most of the fruit flies die, but a few survive. The survivors have genes that protect them from the pesticide. In the future, there will be...

Viruses need energy to survive (true or false)

When a trait is "selected against" this means that the adaptation is....

This is when two species evolve together to maintain an evolutionary relationship.

This is what happens to genetic diversity when gene flow takes place

This is why a pesticide lose its effectiveness over time. The populations develops this...

These are some ways that we can prevent the spread of viruses

This scientist studied evolution and came up with the idea of natural selection.

This is when two parent species evolve into one new species.
