Which sentence correctly describes structures that help cells move?

Biology
1 answer:
Elenna [48]3 years ago
6 0

Answer:

B and C

Explanation:

Option A is incorrect. Microtubules only support and give shapes to cells.

Option D is also incorrect because microfilaments mostly provide supports to cells as well.

<em>The cilia is a slender protuberant structure found on some cells. A variant of the cilia (motile cilia) function in the locomotion of some unicellular eukaryotic organisms using wave-like actions.</em>

<em>The flagella is similar to the cilia in being protuberant as well as functioning as a locomotive structure. However, the flagella is much longer than the cilia and uses whip-like action instead of wave-like action.</em>

Options B and C are correct.

The law of_____
Marta_Voda [28]

Answer:

The correct answer is - segregation.

Explanation:

The law of segregation states that out of two factors or alleles of a gene located in an organism, only one allele or factor is distributed to each sperm cell or egg cell (gamete) randomly, So, the segregation of the alleles are random and only one allele is distributed to each gamete according to this law.

The law of segregation helps in making a different combination of alleles in a particular species or population and leads to variation in genetics. It makes sure that traits distribute to each generation randomly.

Lapatulllka [165]

Given question is incomplete as it lacks the group of choices. However, the group of choices associated with the question is as follows:

1. Organisms must display variation.

2. A trait must increase reproduction.

3. A trait must directly affect metabolism.

4. A trait must increase survival.

5. A trait must be able to be passed on to future generations.

Answer:

The correct answer is : option 3. A trait must directly affect metabolism.

Explanation:

The process that leads to change or adaption in the species or a population of the organism known as natural selection. In this process population exhibits the variation in the population due to the change or adaption.

This variation refers to the better traits and increased reproductive ability, suited to the environment than others which is also known as survival of the fittest as they increase their survival in comparison to the other population or species. Natural selection carries traits that are passed on to one generation to another.

Thus, the correct answer is option Is : 3. A trait must directly affect metabolism.
