<span>The correct answer for this question would be the S phase of the cell cycle. During the S phase, DNA is synthesised in the form of a complete copy, which is stored in the nucleus, as well as acting as a copy for a microtubule-organising structure referred to as the centrosome.</span>
I found the full exercise on the internet and it describes that there are three enzymes and you want to know which are the two enzymes from the <span>digestive tract of the mondoni and which one is the enzyme from a hot spring.
Attached are two graphs from the analysis of the activity of these enzymes regarding temperature and pH. I found these graphs with the full exercise.
The enzymes that probably came from the </span>digestive tract of the mondoni were enzymes A and B. These enzymes were resistant two lower levels of pH which indicates that they could be present in a <span>digestive tract, which tends to be acidic, while the enzyme C does not tolerate lower pH levels. Enzymes A and B were also more active when in lower temperatures that match temperatures of a normal living organism, whereas enzyme C was more active in higher temperatures matching its probable provenience - a hot spring.</span>
Option C
Folic acid is not a common teratogen
<u>Explanation:</u>
Teratogen - Any factor that can interrupt the growth of a fetus or embryo. Teratogens may generate a birth deformity in the child. Or a teratogen may terminate the pregnancy unmitigated. The aspects of teratogens include radiation, parental infections, drugs.
Alcohol exploitation can produce mental obstacles, distortion, germination obstacles, miscarriage, and behavioral complications in newborns. Women who have not taken the hepatitis B vaccine should be held for immunization if they are at danger of sexually dispatched disease or blood appearance. The vaccine may be administered during pregnancy. SSRI antidepressant medications is also a factor of teratogen to cause deformity to fetus growth.
