Ilya [14]3 years ago
7 0

Answer:

(B). inhibiting HMG-CoA reductase.

Explanation:

Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.

It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.

Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.

Thus, the correct answer is option (B).

In a protein supplement that contains 154 total kcalories, 11 grams of protein, and 17 grams of carbohydrate, how many kcalories
Llana [10]

Answer:

In this protein supplement there are 11 grams of protein which contribute with 44 kcalories. Therefore, the percentage of kcalories coming from protein in this particular supplement is 28,5 %.

Explanation:

Each gram of protein contributes 4 kcal (calories), so 11 grams of proteins x 4 kcal/gram = 44 kcal.

The total amount of kcalories is 154, so 44 kcal / 154 kcal x 100 = 28,5%.

When it comes to protein supplements is very important to realise how many proteins are being consumed and how many total calories this supplement has, for the simple reason that it might be not help to reach the protein goal for a particular individual, but instead, it might be providing too many calories that come from non-protein compounds.

Over [174]

ANSWER: CASE-CONTROL STUDY

EXPLANATION:

An epidemiology expert will make use of a Case-control Study for proper determination of association or linkage between the oil spill and the disease outbreak (arthritis).

Case-control Study provides an observational experiment between two existing groups (two reservoirs) differing in outcome (affected and not affected), they are highlighted and compared on the basis of a context (disease outbreak; arthritis).

However, the known group is regarded as the control group and it provides a substantial guide to the confirm the validity of other experimental groups in relation to the general context (outbreak of arthritis).

The nurse palpates the anterior fontanel of a newborn and notes that it feels soft. what does this datum indicate to the nurse?
zalisa [80]

The anterior fontanel is a diamond-shaped area where the frontal and parietal bones meet. It closes between 12 and 18 months of age. Vigorous crying may cause the fontanel to bulge, which is a normal finding. A nurse is performing an assessment on a postterm infant.

<h3>What is anterior fontanel?</h3>
  • This is the junction where the 2 frontal and 2 parietal bones meet. The anterior fontanelle stays soft until about 18 months to 2 years of age. Doctors can consider if there is increased intracranial pressure by touching the anterior fontanelle.
  • The fontanel can broaden in the first few months of life,18 and the median age of closure is 13.8 months. By three months of age, the anterior fontanel is secured in 1 percent of infants; by 12 months, it is closed in 38 percent; and by 24 months, it is closed in 96 percent.
  • The fontanelle allows the skull to distort during birth to facilitate its passage through the birth canal and for expansion of the brain after birth. Skull at birth, showing frontal and occipital fonticuli. The anterior fontanelle normally closes between the periods of 12 and 18 months.

Why do you think that Arjun must continue to take antibiotics for five weeks following his release from the hospital
3241004551 [841]

TLDR: Antibiotics must be taken several weeks to fully kill the bacteria. Else, surviving bacteria develops drug resistance.

Antibiotic prescription really depends on the patient's condition. Some conditions like major surgery or diseases that cause immunosuppression are more prone to bacterial infection, thus they must take antibiotics for prolonged periods of time to fight their current infections or prevent further infections.

Antibiotics, as a general rule, must be given 7 days or several weeks (depending on the bacteria/pathogen) to be sure that all the disease-causing bacteria are dead. If the drugs are taken only until symptoms fade, the surviving bacteria (now fewer in number and not causing symptoms) will develop mutations that may help resist the previously-taken antibiotic, giving rise to drug resistance.

Thus, Arjun must take the antibiotics for several weeks more (according to the doctor's orders, of course) to kill all remaining bacteria and also to prevent bacterial drug resistance. Which is really problematic, since we're slowly losing our number of effective antibiotics.
