H/A Investigation 3 Review

Variation exists even in populations of bacteria that reproduce asexually.

Mutations are a change in the genotype of an organism.

Examples of variations in humans include

The finch feature that made the difference in the survival of the birds on the Galapagos Islands is

A person who has sickle cell anemia must inherit the the recessive allele from both parents to become sick.

The fossil record reveals the relationship between ancient and modern organisms.

Mice living on the lava flow in the deserts of New Mexico actively choose to adapt to that environment.

Which is the most likely response of birds to a food supply of insects living in deep, narrow tunnels?

An inherited trait that increases an organism's chance of surviving in an environment long enough to reproduce is

Mutations can be

Which of the following conditions must exist in order for natural selection to occur?

Which statement best explains the similarities between the limbs?

"Mutations are random, natural selection is not". Which of the following statements does not support this conclusion?

In what major way did Darwin's ideas diverge from LaMarck's?

Mutations are caused by changes in the environment

Unless a mutation leads to death, the mutated gene will be passed on to offspring leading to variation in a population.

Mutations can happen to genes on an organisms DNA during

In class, we used changes in a chocolate chip recipe to represent

The original population of finches on the Galapagos Islands had variation in size and shape of beaks.

What is an inherited trait?

Mutations occur when DNA comes from another source other than the parents.

Which of the following must occur in a population in order for natural selection to occur?

The process of one species developing into two or more species that can no longer mate is called

Bacteria become resistant to antibiotics when a few survive, reproduce and pass this along. This is an example of

The range of differences of traits in a population defines

The frog and the whale are both tetrapods even though the adult whale doesn't have 4 limbs. Evidence that supports this

When is a trait most likely to be passed on to the next generation?

If populations become separated (by geography or behavior) they can become a new species.

The finches on the Galapagos Islands must adapt their beaks to the environment or they will die.

If the surviving walking sticks in a bush environment produce offspring, what might happen to the population?
