Biological molecules such as proteins and DNA reveal differences between humans and chimps that would have taken around 7 million years to accumulate.

<h3>What is DNA?</h3>

All known animals and viruses have genetic information in the form of deoxyribonucleic acid, a polymer consisting of two polynucleotide chains that coil around one another to form a double helix. Ribonucleic acid is a type of nucleic acid, as is DNA.

The two DNA strands are known as polynucleotides because they are constructed from simpler monomeric units called nucleotides.

The four nucleobases that contain nitrogen—cytosine (C), guanine (G), adenine (A), or thymine (T)—along with deoxyribose and a phosphate group—make up each nucleotide. The sugar of one nucleotide and the phosphate of the following make covalent bonds, creating what is known as the phospho-diester linkage, which results in an alternating sugar-phosphate backbone.

Which group serves as the control​ group? A. Group 2 serves as the control group because this group corresponds to the standard
Reil [10]

Answer:

First, let's add the missing piece of information

A school psychologist wants to test the effectiveness of a new method of teaching FrenchFrench. She recruits 100100 firstfirst​-grade students and randomly divides them into two groups. Group 1 is taught by means of the new​ method, while group 2 is taught by traditional methods. The same teacher is assigned to teach both groups. At the end of the​ year, an achievement test​ (graded on a scale from​ 1-10) is administered and the results of the two groups are compared.

The CORRECT ANSWER IS A.

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.

Explanation:

A control group

The control group acts as a baseline treatment that is employed in contrasting it to the other form(s) of treatments.

Ex: In this case study, a school psychologist wants to test the effectiveness of a new method of teaching French, to see if the ones taught by using a new method (are placed in group 1) do better in learning French than those taught with the traditional method (are placed in group 2). The students being taught French with the traditional method (group 2) would serve as the control group (as this is the present, proven and acceptable practice of teaching French. The factor is the method of teaching French. There are two treatments: new method and traditional method.

Therefore, the option A. is THE CORRECT ANSWER

A. Group 2 serves as the control group because this group corresponds to the standard method that will be compared to the other method.

Answer:

Ос.  He used DNA testing to compare evidence to possible criminals.

Explanation:

Detective Scott worked to solve cases by the use of DNA testing which is an efficient way to solve a criminal case because DNA testing provides all information about the criminal. Due to this DNA testing, he solved many cases  and the criminal caught with the help of this testing. If he can't use this DNA testing method then the case would not be solved.
