Once a species has been subjected to a new environmental pressure the next step to survival is what?

Question

a.reproduction
b.selection
c.evolution
d.macro evolution
e.adaptation
f. gills
h.predators.
i.fitness
j.none of the above.

Answer 1

e.adaptation

The pieces fit together like this: Some members of the species will ADAPT to better survive the new pressure--those members are more FIT than the others, and so they will be SELECTED, and will pass along their genes through REPRODUCTION. Their offspring will share their adaptive traits, and this is EVOLUTION.

PREDATORS are an example of an environmental pressure.
GILLS are an example of a trait that is adapted for.

Answer 2

The next step would be adaptation and selection. Both go hand in hand. the weaker ones get deselected while the strong adapt to the pressures.

Answer 3

Ugh, I hate this. If you move to Denver, Colorado, your body will attempt to adapt to the higher altitude / lower oxygen pressure. If you cannot adapt, you will die. If you die, you cannot reproduce, LOL.

If you answer this way, you will probably get the question wrong, but here's my timeline:
1) Attempted adaptation to the new conditions
2) Death of those individuals completely unfit for the new environment
3) Selection for those who are better-adapted to the new conditions.

Answer 4

I think j. is correct. "None of the above" looks right to me.

The correct answer should be Natural Selection. That is, the new environment will "select" for those entities that have the ability to best survive and reproduce in the new conditions.

Answer 5

You can test this yourself.

Jump in the water. You wont try to walk around nor will you behave as if you are on land. You will swim, you will try hard to keep your head up, ie- you will adapt.

Answer 6

we can adjust to anything in time.

Answer 7

E. ADAPTATION
