Answer:
Buffy coat.
Explanation:
Between the plasma, and red blood cells the platelets, and white blood cells form a thin white layer which is known as Buffy coat following density gradient centrifugation of the blood.
Centrifugation is the process where the distinguish between cell fragments, and cell from the liquid intracellular matrix occurs. Centrifugation is a technique which separates the particles according to their size, density, viscosity and shape with the help of centrifugal force.
Answer:
The answer might be D
Explanation:
The answer could be D because birds with larger beaks should be capable of eating soft shell seeds, as well as hard shell seeds. So natural selection would not occur because the finches with large beaks would not die as a result of not eating soft shell seeds. The finches with large beaks should be able to reproduce offspring with the same trait. And so should the finches with small beaks.
Site-specific recombination systems all of the choices are correct i.e.
A. do not depend on extensive nucleotide sequence homology.
B. depend on enzymes that are often specific for sequences within the host.
C. are features of some viruses.
- An exchange between two specified sequences (target sites), either on the same DNA molecule or on two separate DNA molecules, is known as site-specific recombination.
- DNA sequences may be integrated, excised, or inverted as a result of the exchange.
- A site-specific recombinase that can work by itself or with the aid of additional components or enzymes shapes the DNA target during recombination.
- The recombinase is chemically bonded to the ends of the intermediate DNA after DNA breakage at the recombination site; when this process is reversed, the intermediate DNA is resealed to form the recombinant and the recombinase is released.
- During this recombination process, neither replication nor repair are necessary.

The smaller cell because it has less distance in the cell, so it will occur quicker.
