Answer: Cynobacteria

Explanation:

The Precambrian time is the earliest period of earth history. It is preceded by the Cambrian time hence got the name. The earliest living organism in the Precambrian time was the Cynobacteria. It has been found in the fossil record of 3.4 billion years ago. They were the primitive organisms which were capable of conducting photosynthesis and producing oxygen. The abundance of Cynobacteria has resulted in the increase in abundance of oxygen into the atmosphere.

A gene editing technology called CRISPR-Cas9 uses cellular machinery to change the cell's genetic material. How might this techn
inna [77]

Answer:

B

Explanation:

CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.

In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.

After three days of taking a selective serotonin reuptake inhibitor (SSRI), Derrek is disappointed because he is not feeling any
Evgesh-ka [11]

Answer:

Weeks.

Explanation:

Selective serotonin reuptake inhibitors are common antidepressants prescribed for patients with depression and anxiety disorders. However, these medications do not have an immediate effect. They usually have full effect within weeks, depending on the patient.

This delay, can be explained by the mechanism of action of these drugs. Selective serotonin reuptake inhibitors act by blocking the serotonin transporter which transports serotonin into the brain cells.This results in more being available outside the cells where it has it effects.

SSRIs don't work instantaneously because they do not target the transporter directly. They rather, bind to the DNAs that produce the transporter and therefore makes them less active and this leads to lower amount of transporters available. This process takes time.
