The correct answer is D. for sure.
<span>The normal daily input of water is about 2.5 L from beverages food, and metabolism. The normal daily output of 2.5 L consists of 1.8 L in urine, sweat, and feces, plus 0.7 L in insensible water loss. Insensible water loss is water that evaporates through the skin and from the respiratory tract. Insensible losses account for 0.7 L of water loss per day. The average human exhales an average of 0.35 L of water each day. This corresponds to about 14% of water lost through respiration.</span>
Answer:
Allele. An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. ... An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.
Biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.
<h3>What is the circadian rhythm?</h3>
The circadian rhythm refers to the biological process regulated by the duration of a calendar day, which is common for many organisms ranging from animals to plants.
The circadian rhythms enable the maintenance of homeostatic control of physiological functions and thus perform metabolic activities.
In conclusion, biological processes that systematically vary over a 24-hour cycle are called circadian rhythms and are regulated by a cluster of neurons called the suprachiasmatic nucleus.
