Two of the four major divisions in the geologic time scale are the Archean eon and proterozoic eon.
<u>Explanation:</u>
The Arcean eon is dated from 3900 million years ago to 2500 million years ago. It was in this period the oldest known rocks were deposited. At that time the atmosphere of earth was composed of gases like methane, carbon monoxide, ammonia etc.
The Proterozoic eon is dated from 2500 million years ago to 540 million years ago. It was by the end of Proterozoic era that the Eukaryotas came into existence.
There are some similarities and differences between Archean eon and Proterozoic eon. Stromatolites formed by the colonies of cyanobacteria lived in both the eras. This is one similarity between both the eras.
The weather in the Archean era was hot and wet while the climate and weather of proterozoic era was different from this. Proterozoic era experienced two ice ages.
Answer:
E- None of the above
Explanation:
None of those things are signs of global warming.
P.S - Check my answer first I am not 100 percent sure my answer is right but it is my best guess.
<span>The movement of fluids between cellular compartments is regulated by osmotic and hydrostatic forces.</span>
<span>
Hydrostatic pressure<span> is the force exerted by a fluid against a wall which causes movement of fluid between compartments. This pressure is important for exchanging plasma and nutrients between capillaries and surrounding tissues</span> and also in the nephrons (kidneys) where ensures proper filtering of the blood to form urine.</span> <span>Fluid also moves between compartments along an osmotic gradient (the difference in concentration of solutes on one side of the cell membrane to that on the other side). Water constantly moves into and out of fluid compartments via osmotic gradient.</span>
This type of molecule is the MOST common energy source for all cells and enters the cell by facilitated diffusion. The molecule is the molecule ATP or the Adenosine Triposphate which is made in the mitochondria of cells.
The insurance from overstretching. Elastic filaments help to shield the muscle from overstretching and furthermore help in returning it to typical length. Titin is a mammoth protein, more noteworthy than 1 µm long, that capacities as a sub-atomic spring which is in charge of the inactive flexibility of muscle. It is made out of 244 separately collapsed protein areas associated with unstructured peptide arrangements.
