Answer:

The correct answer is: Protease inhibitor.

Explanation:

A protease inhibitor is a type of antiviral drug that is used mostly to treat AIDS and Hepatitis C.

Protease inhibitors work by blocking proteolytic cleavage of protein precursors so they can impede viral replication.

Protease inhibitors are very successful in the treatment of these diseases but they can have some side effects, like generating diabetes and kidney stones.

How do archaea and bacteria differ?​
Lunna [17]

Answer:

The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.

Explanation:

The differences between Archaea and bacteria:

1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.

2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.

3. The genes of the archaea are more similar to the eukaryotes than the bacteria.

4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).

5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.

The first step leading to angiotensin II production is the secretion of what by the kidneys? Multiple Choice Calcitriol Angioten
Pachacha [2.7K]

Answer:

The correct answer is "Renin".

Explanation:

The secretion of the enzyme renin by the kidney is one mechanism used by the kidneys for blood pressure regulation. The secretion of renin is the first step leading to angiotensin II production, in what is known as the renin–angiotensin system (RAS). Renin catalyzes the conversion of  angiotensinogen to angiotensin I, which is subsequently converted to angiotensin II by the angiotensin-converting enzyme (ACE).

Pepsi [2]

Ans.

<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.

Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.

Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.

Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
