The DNA in the nucleus and mitochondria are the same.

This is not exactly true, although they are similar. This is not a correct option.

The following three are correct options:

Mitochondria and chloroplasts grow independently from the cell.

This is true, and supports the idea that they previously existed as their own organisms.

Prokaryotic cells, mitochondria, and chloroplasts are all the same size.

All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.

Mitochondria and chloroplasts contain their own ribosomes.This is true as  well.

Answer;

5. the flipper of a dolphin and the arm of a koala

Explanation;

Homologous structures are body structures that share a common origin, the degree at which these structures resemble each other can be used to infer the closeness of evolutionary relatedness.

-A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. It's when very different animals have bones that appear very similar in form or function and seem to be related. For  example; the flipper of a dolphin and the arm of a koala.

All living organisms are made of only 20 different aminoacids- this is the correct answer! This means that the genetic code only codes for those 20 aminoacids (for example Glutamine and  Lysine).

Answer: Discriminative stimulus

Explanation:

A discriminative stimulus is associated with reinforcement or punishment, that exerts control over a particular form of behavior. The subject discriminates between closely related stimuli and elicits a specific behavior only in the presence of that stimulus. T<u>his stimulus increases the probability of a given response</u> because of their historical correlation with the availability of reinforcement for the response.

In this example, the hungry rat gets food if it presses a bar only when the light is on. The rat learns that is most likely to request this food in the future in the presence of this light, because historically, the request has been reinforced in the presence of this light. <u>The light in the example became a discriminative stimulus and it evokes the response.</u>
