The answer to this is: C) a factor that may affect an experiment or investigation. This is the best answer. A and B can be eliminated. D describes a controlled variable which is more specific than a scientific variable, thus C is the best answer. It is the best description of just a scientific variable. And, The second one is B: Robert Hooke was a famous scientist who experimented with springs (metal coils). He found that the farther you stretched the spring, the larger the force with which the spring pulled back on you.

Identify a scenario where an experiment would be replicated
Vsevolod [243]

Answer:

If you did not follow the procedure as you should have.

Explanation:

You may have to repeat an experiment for several reasons. It can be because you need to be certain of the results so that you have to perform it several times. Or you need more precise results so that you can fine-tune the variables and repeat the experiment again.

The most common scenario where an experiment would be replicated would be in a situation where you did not follow the procedure that you have outlined exactly like you should have so that the results you got are not 100% reliable. In such a case, the experiment would need to be replicated for the correct results.

I hope this answer helps.

miss Akunina [59]

After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.

<h3>What, according to Darwin, is artificial selection?</h3>

Artificial selection is the discovery of desirable qualities in plants and animals by humans, as well as the procedures taken to improve and maintain such traits in future generations.

They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.
