Answer:
Option B) functions to increase sodium reabsorption.
Explanation:
Aldosterone is an hormone secreted by the cortex of the adrenal gland. The adrenal gland is situated at the superior poles of the right and left kidneys.
Aldosterone regulates sodium homeostasis and as such helps to control blood volume and blood pressure.
Aldosterone is secreted in response to decreased blood pressure (hypotension) to increase sodium reabsorption from urine, sweat, and the gut. Also excessive aldosterone levels (too high sodium) can lead to high blood pressure (hypertension).
Body fossils include molds and casts. A mold is the imprint left by the shell on the rock that surrounded it. Molds of the underside of shell may be left on the surface of rock that formed when sand or mud filled the inside of the shell.
Answer:
Land and sea breezes are wind and weather phenomena associated with coastal areas. A land breeze is a breeze blowing from land out toward a body of water. A sea breeze is a wind blowing from the water onto the land. Land breezes and sea breezes arise because of differential heating between land and water surfaces.
Explanation:
Land breezes come from land while sea breezes come from the ocean or other large bodies of water. While a land breeze is formed at night, a sea breeze is formed at daytime. Land breezes are more often experienced during autumn and winter while sea breezes often occur during spring and summer months.
Mutation is a sudden change that occurs in the gene sequences. Mutation can have both positive or negative effect on living organisms. It can lead to disorders and also one of the ways that causes evolution of the species.
Due to mutation, the gene sequences changes due to which the amino acids encoded during the process of translation also changes. If different proteins are formed then the function that was supposed to be performed by the proteins of non-mutated genes varies.
Hydra has two main body layers, which makes it "diploblastic". The layers are separated by mesoglea, a gel-like substance. ... The cells making up these two body layers are relatively simple.
