Answer:
Mercury
Explanation:
The planet from which you will have the easiest time escaping its gravitational pull is the one with the weakest gravity. Since gravity is directly proportional to mass, the larger or more massive a planet is, the higher the gravity. Therefore, the smallest planet would have the weakest one. Since Mercury is the smallest planet in the solar system, it would also have the weakest gravity, and would therefore be the easiest to escape from. Hope this helps!
The right answer is A: intercellular communication.
An example of intercellular communication is the one between the kidney, liver and lungs to preserve water-soluble homeostasis.
Angiotensinogen, an inactive protein produced by the liver, circulates in the blood. It is the precursor of the active peptides angiotensin I and II, and the only substrate of renin.
In the event of a drop in the pressure in the renal artery, renin (an enzyme sometimes considered as a hormone) is secreted in the kidney by differentiated myoepithelial cells of the arteriole afferent of the juxtaglomerular apparatus. There are also other stimuli promoting renin secretion: decreased natremia in the distal convoluted tubule, ß-agonists, hyperkalemia, PGI2 and stimulation of juxta-glomerular cells by the sympathetic nervous system)
The angiotensinogen is cleaved by the renin and forms a decapeptide called "angiotensin I", inactive.
Angiotensin I will then be converted primarily to angiotensin II by a carboxypeptidase, the angiotensin converting enzyme. This enzyme, secreted by the liver, acts at the pulmonary level.
D) Have chemical receptors for taste on their legs
Answer:
The Kingdom of Protista
Explanation:
Organisms that belong to the kingdom Protista are unicellular, and eukaryotic (cells with a true nucleus and membrane-bound organelles). Protists can be both heterotrophic and autotrophic, and they usually move by flagella or cilia.
