Answer:
Primary active transport
Explanation:
Active transport may be defined as the movement of particles against their concentration gradient with the help of an energy source like ATP. Two main types of active transport are secondary active transport and primary active transport.
Primary active transport includes the sodium potassium pump because it directly uses the stored chemical energy in the form of ATP. Three sodium moves out of the cell and two potassium moves inside the cell with the help of ATP.
Thus, the correct answer is option (a).
One of the main medical reasons as to why one might avoid vaccination is that the individual may present allergies.
Allergic reactions can range from mild to severe and <em>life</em>-<em>threatening</em>. <u>Mild allergic </u>reactions will <em>rarely </em>be a solid reason to avoid vaccination, however, there are cases in which one might present severe allergic reactions to the <u>contents </u>of a vaccine.
Therefore, we can confirm that one of the<em><u> only and main reasons </u></em>to not get vaccinated is if your physician has instructed you to avoid the vaccine due to a possible severe allergic reaction.

Urinary strictures
Bethanechol chloride (Urecholine) can be harmful to patients who have a urinary tract obstruction or bladder wall weakness. The medication has the ability to contract the bladder, causing pressure to build up in the urinary tract. In these patients, an increase in urinary tract pressure could cause the bladder to rupture.
What is Urinary retention?
- The inability to completely empty the bladder is referred to as urinary retention. The onset can be abrupt or gradual.
- Symptoms of sudden onset include inability to urinate and lower abdominal pain.
- When symptoms appear gradually, they may include loss of bladder control, mild lower abdominal pain, and a weak urine stream.
- If there is an obstruction or stricture (narrowing) in or around the bladder, or if the muscles in or around the bladder are weak, urine may be retained. Urinary retention can also be caused by certain types and locations of tumors, certain medications, being dehydrated, or having constipation.

Answer:
The correct answer is D.
Explanation:
Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.
Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to <em>help the right atrium to dilate without much wall stres</em>s.
