the years 1873–76 which, among many other discoveries, catalogued over 4,000 previously unknown species.
Explanation:
Answer:
D. Only Plant Cells have Chloroplasts that help make food during photosynthesis.
Explanation:
I always think of it like this-
Plants are green...What make them green? Chloroplasts
Animal cells are not green because they do not have chloroplasts.
A cannot be the answer because animal cells also have cytoplasm that suspend organelles.
B cannot be the answer because all cells come in a range of sizes and some plant cells can be bigger.
C cannot be the answer because some animal cells can have vacuoles.
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.
