Answer:
Explanation:
Aldosterone is a hormone which is produced by the adrenal glands which are present above the kidneys. The role of aldosterone is to regulate the blood pressure. It causes the reabsorption of water and salts into the bloodstream during the kidney filteration process. Hence, maintains the blood volume, restors blood pressure and salt level.
Renin is an enzyme. It facilitates chemical reactions which stimulates the synthesis of angiotension II, it directs the synthesis of aldosterone.
The right answer is C. I think, a. and d. are obviously not serious. B is not true, because Ag and Au are in the same group in the periodic table and therefore have the same number of electrons in the last level. So, they form ions with the same charge. C is true beacause Ag and Au have different numbers in the periodic table and different amount of protons and neutrons in their nucleuses.
Answer:
Option A, Key stone
Explanation:
A keystone species plays a major role in an ecosystem as it is the species whose presence effects all other species in the ecosystem .In general a keystone species is always a dominant predator that feed on prey population. If it is removed, the prey population will explode and the population diversity will reduce. For example - bison, prairie dog etc.
Hence, option A is correct
The answer is Ser-Arg-Ala-Val-Gly-STOP
It is known that three nucleotide bases on mRNA are called
codon and that each codon codes for the specific amino acid. According to the
genetic code chart, the following mRNA sequence will code for the following
amino acid sequence:
mRNA sequence: <span>UCU CGA GCC GUU GGG UGA</span>
Amino acid sequence: Ser Arg Ala Val Gly STOP
Technically all of them depend on your nervous system. the respiratory, endocrine, skeletal, cardiovascular, digestive, and urinary. all of these are influenced by the nervous system.
