Answer:
<h2>In 1992, the U. S. Public Health Service (PHS) recommended that all women of childbearing age consume 400 micrograms (0.4 milligram) of folic acid every day to reduce their risk of having an NTD-affected pregnancy.</h2>
Answer:
Lactate: fermentation in human muscle
Ethanol: fermentation in yeast and bacteria
Acetyl CoA: aerobic oxidation
Explanation:
Lactate is produced in lactic fermentation in human muscle. Lactic fermentation in muscle cells is a process that occurs alternatively, in situations where the body does not perform aerobic respiration. Considered a short-term metabolic device, activated when the body is subjected to intense physical effort under conditions of low muscular oxygenation.
Alcoholic Fermentation, also known as ethanol fermentation, is the anaerobic pathway performed by yeast and some bacteria, in which simple sugars are converted to ethanol and carbon dioxide. Yeasts usually function under aerobic conditions, either in the presence of oxygen, but are also capable of functioning under anaerobic conditions, or in the absence of oxygen. When oxygen is not readily available, fermentation alcoholic beverages occur in the yeast cell cytoplasm.
Acetyl CoA results from aerobic oxidation. This process occurs in mitochondria during cellular respiration, where pyruvate, the product of glycolysis, can be substituted, and often is, by fatty acids. This is because pyruvic acid is used to form a compound called Acetyl Coenzyme A or Acetyl CoA. In this sense, Acetyl CoA can also be produced by the degradation of fatty acids by a reaction called β oxidation.
Answer: B
Explanation:
Ammonia is so toxic that it can be transported and excreted only in large volumes of very dilute solution. As a result most terrestrial animals simply don't have access to sufficient water to routine excrete ammonia.
The main advantage of urea is its very low toxicity. Animals can transport urea in the circulatory system and store it safely in high concentrations. Also much less water is loss when a given quantity of nitrogen is excreted in a concentrated solution of urea than would be in a dilute solution of ammonia.
Answer:
The correct answer is C) It catalyzes the lengthening of telomeres, compensating for the shortening that could occur during replication without telomerase activity.
Explanation:
While replicating, the ends of the chromosomes always lose a part of the ends, therefore, the telomerase catalyzes this growing process, somehow compensating the information that will be lost.
