Answer:

Lower esophageal sphincter

Explanation:

The biological valves are the muscular structures composed of the smooth muscles which form thick tubular structure to allow the controlled movement of any material through it. The valves in the digestive system are known as the sphincters.

The sphincters control the unidirectional movement of the eaten food, chyme and the bolus in the digestive tract.

A sphincter is present at the lower portion of the oesophagus (food pipe) which contracts to prevent the backflow of the food from the stomach and since the sphincter is present at the lower side of the oesophagus, therefore, is known as the lower esophagal sphincter.

Thus, Lower esophageal sphincter is correct.

How will the cardiac output change if you double the heart rate but reduce the stroke volume by one-half? how will the cardiac o

melamori03 [73]

<span>The answer is that there will be no change.

The cardiac output is the volume of blood pumped by the heart per unit time.

Multiplying the stroke volume and the heart rate gives you the cardiac output. The cardiac output for a person at rest is approximately 5L per minute.</span>

Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 o

mezya [45]

The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.
