Answer:
D. Because science only uses facts that are proven 100% true through the use of variables.
Explanation:
All the knowledge we read is science books are not merely some observed facts but the result of a systematic scientific methodology through which facts are tested. Science only gives us that knowledge as facts which is proven 100% true through the use of variables.For example: if a scientist has studied the effect of salt stress on the growth of plants and he got the results in form of graphs which show that growth of salt treated plants in very less than normal plants. Then he needs to draw conclusion after consulting relevant previous experiments and say that salt stress hinders growth and why? with reasonable logic.
Variables are the things hat he changes like environmental conditions in previous example to see that in changed conditions plant is showing changed behavior. This way a scientist strengthens his results. Therefore, we can say that whatever knowledge we get through science is proven 100% true through the use of variables.

Answer: alarm and resistance
The exhaustion stage of stress originates from <span>the first two stages of the cycle of stress, the alarm resistance. tress, </span>and<span>Once alarm ( where the body system is flooded with adrenaline) is ended, resistance sets in and finally, exhaustion takes over when the body runs out of energy.</span>
The two domains are the Archaea (Archaebacteria) and the Bacteria (Eubacteria).
Archaea are the prokaryotic cells, unlike the Bacteria and the Eukarya, the Archaea possess the membranes comprising of branched hydrocarbon chains connected with the glycerol by the ether linkages. The Archaea generally thrives in extreme environments and comprises methanogens, hyperthermophiles, and halophiles.
The Bacteria are also prokaryotic cells, and unlike the Archaea and the Eukarya, the cell walls of Bacteria comprises of peptidoglycan. Bacteria comprise cyanobacteria, mycoplasmas, Gram-negative bacteria, and Gram-positive bacteria.
