Please help me because I don’t know

Answer:

Hello. You forgot to provide the answer options and the text they are related to. The text and answer options are in the attached image and the correct answers are:

1. dna extraction

2. polymerase chain reaction

3. controls

4. restriction enzymes

5. gel electrophoresis

6. southern blot

7. hybridization to a probe

8. dna fingerprint

9. compare the sample to modern dna samples

Explanation:

As can be seen, from the answers given above, we can see that a molecular analysis was made, using biochemical methods and protocols related to molecular biology, capable of identifying the molecular composition of a biological tissue. This was able to determine the descendants closest to the human remains found and analyzed. The methods and analyzes used are recognized scientifically and used for a long time and by scientists recognized worldwide, which increases the fidelity and credibility of the presented results.

When biological evidence is available, DNA can be used to identify criminals with amazing precision. When a suspect is identified, evidence from the crime scene can be compared to a sample of that person's DNA.

The answers for the case:

1. DNA extraction

2. Polymerase chain reaction

3. Controls

4. Restriction enzymes

5. Gel electrophoresis

6. Southern blot

7. Hybridization to a probe

8. DNA fingerprint

9. Compare the sample to modern DNA samples

Reasons for the answers:

1. You must first extract the DNA from the sample. To avoid contamination, this (and all subsequent processes) must be done with extreme caution.

2. You can use the polymerase chain reaction to amplify DNA (random priming will allow you to amplify all the DNA rather than a specific fragment).

3. A positive control (such as a modern DNA sample) would be used to ensure that the procedure is working properly.  A negative control (no DNA) would indicate that there was no contamination.

4. Restriction enzymes, such as VNTRs, can be employed to isolate the genes of interest.

5. Smaller fragments migrate quicker than larger pieces during gel electrophoresis.

6. To prepare DNA for probing, Southern blotting is utilized.

7. The probe binds to the gene of interest and can be seen on a microscope (by autoradiography for a radioactive probe).

8. This fingerprint technology is now commonly used to identify human remains, match a suspect, and determine paternity to a crime scene sample.

9. The laboratory will want to have their known biological samples accessible for a side-by-side comparison of the victim's or suspect's DNA profile to the retrieved crime-scene DNA.

Answer:

Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. ... Degrees of longitude are divided into 60 minutes.

Longitude is the measurement east or west of the prime meridian.

Answer:

B) Opposed a national bank

Explanation:

Thomas Jefferson opposed this plan. He thought states should charter banks that could issue money. Jefferson also believed that the Constitution did not give the national government the power to establish a bank.

Answer:

4. The population of predators would decrease.

Explanation:
