Answer:
(B)iology
Explanation:
Biology is a branch of science that studies about the living organisms.
Answer:
Angiotensin II is a potein VASOCONSTRICTOR that helps regulate blood pressure. Angiotensinogen, is an inactive hormone synthesized and released continuously from the LIVER. Its activation, which occurs within the BLOOD, is initiated by the enzyme renin. Renin is released from the juxtaglomerular apparatus of the KIDNEYS in response to either (1) LOW blood pressure (as detected by decreased stretch of BARORECEPTORS within granular cells, or by decreased NaCl detected by CHEMORECEPTORS within macula densa cells); or (2) stimulation by the SYMPATHETIC division. The sequential action of renin and angiotensin converting enzyme (ACE) causes the formation of angiotensin II (the active form of the hormone).
Explanation:
Angiotensin is a peptide hormones that regulate blood pressure by causing increase in blood pressure through vasoconstriction. It is a part of the renin- angiotensin system that regulate the internal pressure of the blood. It is stimulated when the level of blood pressure reduces or there is an decrease in the sodium chloride in the blood. It effects is to vasoconstrict the blood vessels thereby increasing the blood pressure in the vessels. Angiotensinogen is the inactive hormone synthesized by the liver and upon activation through baroreceptors or chemoreceptors, the liver releases angiotensinogen into the blood stream to be ctivated by the enzyme secreted from the kidney's juxtaglumerular apparatusand then activated to teh angiotensinogen I, angiotensinoI is then activated into angiotensin II by the angiotensin II by the angiotensin converting enzyme. Angiotensin also causes the increase in the aldosterone secretion from the adrenal cortex to promote the retention of sodium by the kidneys, this also helps to increaee the blood pressure. Various receptors helps in signalling the body to a reduced blood pressure level. This includes the baroreceptors which are pressure receptors and detect changes in pressure of the blood; chemorecptors which are chemical receptors that detect the change in the concentration of sodium and chloride ion in the blood. All this function together with the sympathetic division of the CNS to help the body regulates its change in blood pressure in a given time.
Salt marshes are primarily influenced by the tidal flow.
The epidermis, or top layer of your skin may be damaged. The epidermis is made up of mostly dead skin cells to protect your body from small scrapes. If the cut is deep enough ot might affect the dermis, or lower layer of the skin that contains nerves and fat to warm your body.

Scientific drawing is made-up to be precise and founded on real living things or fossils. Artistic drawings do not have to have any origin in realism and it can be abstract and it does not have to tolerate any similarity to any real life object. Artistic drawings are not unavoidably meant to be a faithful reproduction of anything in nature even though that was once the aim in the distant past before the invention of photography. Constructing good biological drawings be situated significant in that they aid to develop more accustomed with the topic over vigilant consideration to the smallest feature. Drawings allow to progress observational skills which is the principle of good science. Good drawings are those that abridge, highlight, review, and explain all at once. For these explanations, consideration to the smallest feature is precise significant. Biological drawings are not destined to be artistic masterpieces but are more like graphic notes that help record a set of observations. As such, these observations must be accomplished in class with the specimen directly observable.
