A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
<h3>What is antigenic drift?</h3>
Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).
For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.
Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

The nurse determines that the client experiencing Metabolic Alkalosis imbalance.
When digestive difficulties throw off the blood's acid-base equilibrium, metabolic alkalosis results. Additionally, it might be brought on by illnesses of the heart, liver, or kidneys. Typically, metabolic alkalosis poses a minimal danger to life. Once it has been treated, it has no aftereffects on your health.
The use of diuretics and external loss of gastric secretions are the two most frequent causes of metabolic alkalosis.
The pH may be high or close to normal in metabolic alkalosis, which is primarily characterized by an increase in bicarbonate (HCO3) with or without a compensatory increase in carbon dioxide partial pressure (Pco2). Prolonged vomiting, hypovolemia, the use of diuretics, and hypokalemia are common reasons.

Answer:
The best answer to the question: When the corpus luteum degenerates:___, would be, E: All of the above.
Explanation:
The process of human female reproduction is a very complex one. But center in it is the corpus luteum, a structure that develops from a follicle in the ovaries and which will be responsible for producing estrogens and progesterones to maintain pregnany in case there is egg fertilization, or, the dismantling of everything by decaying and thus stopping the outpour of these gonadal steroids. When fertilization occurs, the corpus luteum, by producing estrogen and progestorone, inhibits the further production of LH and FSH, and thus the entire process for a successful pregnancy takes place. But when this does not occur, LH and FSH increase again, progesterone, most especially, decreases, and as a result, the endometrium, which had been prepared for implantation, sloughs off. This is why the answer is E.
