Mashcka [7]
No. It was an idea that yielded common positive results. “Not a good theory” is biased terminology. New technology can yield new information, but it does not mean that it was not a good theory.

julia-pushkina [17]

Answer option:

1. duplicate themselves

2. convert energy

3. selectively exchange materials

Answer:

4. all of the above

Explanation:

Cells carry out many functions. They are able to replicate their DNA and divide into two identical daughter cells in order to proliferate.

They can convert glucose into cellular energy (ATP) through respiration in the mitochondria

They can exchange materials with the outside environment via the selectively permeable cell membrane, endocytosis and exocytosis and active transport via membrane proteins.

Mashcka [7]

Answer:

b. the bottleneck effect.

Explanation:

The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.

The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.

The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.

Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.
