Question 10

Which statement describes the most likely impact of the mutation in the mutated sequence?

Accepted Answer

The protein formed will NOT be the same as that formed from the original sequence.

Answer

There will be no effect because the rest of the DNA is normal.

How did the temperature of gases that were ejected from Mount Pinatubo compare to the temperature of gases ejected from other volcanos?

Question 12

How did La Nina event affect the rate of photosynthesis of plants in the tropical forests of Central America?

Accepted Answer

The rate of photosynthesis will decrease because the graph shows the plants will have less sunlight and take up less carbon dioxide.

Answer

The rate of photosynthesis will increase because the graph shows the plants will take up more carbon dioxide from the sunlight.

Answer

The rate of photosynthesis will not change because the graph shows that there is no effect on the carbon dioxide intake.

Question 13

Which statement can CHALLENGE the biologists' claim that purple flowers attract more pollinators than the other color of flowers?

Accepted Answer

Answer

amplitude only

Answer

wavelength only

Answer

neither amplitude nor wavelength

Question 15

Based on the information from the cross section, select 3 statements that are most likely correct.

Accepted Answer

Layer C is below Layer B, so Layer C is older.

Accepted Answer

Layer A is at the top so it is the youngest layer.

Accepted Answer

The ammonite fossil is above the crinoid fossil, so the crinoid is older.

Answer

There is no coral fossil in Layer D, so corals must have become extinct.

Answer

The gastropod fossils are above the crinoid fossil, so gastropods evolved from crinoids.
