Answer:

The correct answer will be- control samples.

Explanation:

A scientific experiment is performed to test the proposed hypothesis because on the basis of results the hypothesis could be proved and disproved.

The experimental design must contain two types of experimental samples: the samples on which the experiments are performed called "experimental samples" and the samples which act as a reference to the experimental samples called "control samples" as they lack the variable to be studied.

In the given question, the statements provide the clue that the experiment is performed on the experimental samples whereas the control sample on which the variable to be studied is missing.

Thus, control samples are the correct answer.

How can scientist explain our ability to feel empathy? Can evolution explain the types of group’s primates will organize themsel
Temka [501]

Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.

<h3>Can evolution explain the types of primates in the group into which they will organize themselves?</h3>

As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.

<h3>How is Homo sapiens different from other non-human primates?</h3>

Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"

With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.
