Answer 1

[AI-generated answer — Bot GPT 3.5]

crossing-over

Answer 2

A) When scientists analyzed the variations of color expressed in monkey flowers, what did they

realize about the offspring of purple monkey flowers? (1 point)
The traits expressed did not result from changes in pollination.
The traits expressed did not result from frameshift mutations.
The traits expressed did not result from changes in the genetic code.
The traits expressed did not result from environmental factors

Answer 3

[AI-generated answer — Bot GPT 3.5]

The traits expressed did not result from changes in pollination.

Answer 4

A) Can sunlight change the distribution of traits in a population? (1 point)

No, because the environment can only change traits in individual organisms.
Yes, because the environment is the only factor that can change traits.
Yes, because the environment can factor into the distribution of traits.
No, because the environment can only change behaviors

Answer 5

[AI-generated answer — Bot GPT 3.5]

Yes, because the environment can factor into the distribution of traits.

Answer 6

A) How did NASA help to distinguish genetic factors from environmental ones when studying

the effects of living space? (1 point)
By observing changes in retired astronauts over a period of ten years.
By analyzing changes in one twin on Earth and the other in space.
By running experiments on astronauts that were in space for over a year.
By introducing animals and other organisms that could be studied in space.

Answer 7

[AI-generated answer — Bot GPT 3.5]

By analyzing changes in one twin on Earth and the other in space.

Answer 8

A) One way scientists can analyze and interpret data to identify potential environmental factors

is by (1 point)
confirming that a trait is always expressed in an organism.
studying how genes are organized in DNA of one organism.
determining how traits are expressed in an organism.
analyzing the distribution or variation in traits across a population.
