The answer would be:

Platelets stick to the damaged area of a blood vessel and help seal the break.

Platelets are blood cells that play a role in blood clot formation. It also helps with blood vessel repair. The process by which platelets stick to the damaged area of a blood vessel is called adhesion. When platelets stick to the damaged blood vessels they release chemical signals to attract more platelets to the site of injury

mart [117]

Answer:

Option A, a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract

Explanation:

The complete question is

If you were working for a pharmaceutical company as part of a drug discovery team, which of these enzyme inhibitors would you suggest as a productive avenue for drug development?

a) a drug to treat high blood pressure that reversibly inhibits an enzyme catalyzing production of a chemical that causes blood vessels to contract

b) a drug to treat diabetes that irreversibly inhibits an enzyme in the metabolic pathway to synthesize glucose

c) a compound that acts as a competitive inhibitor for a digestive enzyme produced only in the presence of certain foods

d) a compound that inhibits enzymes by significantly changing the ph throughout the body

Solution

Productive avenue of a drug simply means producing an drug that not only treats the main disease or disorder but also functions to inhibit the causative agent activity. In case of option A, both the objectives of producing drug are met and hence it is the right choice.

High blood pressure usually affects the blood vessels by narrowing them and in severe cases may rupture them. If a drug as stated in option A is produced, it will not only rectify the effects of high blood pressure but will also prevent the blood vessels from narrowing by inhibiting the activity of enzymes responsible for producing chemical that leads to blood vessel contraction.

Hence, option A is correct

If a hypothetical cell contained 1% saline and 5% glucose, approximately what
liraira [26]

The hypothetical cell will approximately contain 94 percent (94%) of water.

  • If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.

  • If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.

  • Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.

  • In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).

What is the sympathetic nervous system and what are some of the effects it has on the body?
Alex Ar [27]
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate.
