Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
The answer is the last one. Countercurrent multiplication in the kidneys is the way toward utilizing vitality to create an osmotic slope that empowers you to reabsorb water from the tubular liquid and deliver concentrated pee. It is discovered broadly in nature and particularly in mammalian organs.
Countercurrent multiplication was initially considered as a system whereby pee is gathered in the nephron. At first, concentrated in the 1950s by Gottschalk and Mylle following Werner Kuhn's hypotheses, this instrument picked up notoriety simply after a progression of confounded micropuncture tests.

i think it would be true but not 100% sure
Blood pressure
This is indicated in Starling's Hypothesis in which there is fluid movement due to filtration across the wall of capillary. This is dependent between hydrostatic pressure gradient and oncotic pressure across the capillary. The balance of these forces allow the net driving pressure for filtration. The net fluid influc is proportional to this net driving pressure. The leakage of proteins across the capillary membrane has important effects and has corresponding cause in the balance of forces.
