slava [35]

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).

1. Which of the following are factors that both unicellular and multicellular organisms actively balance in order to achieve hom
MrMuchimi
The correct options are as follows:
1. C
Homeostasis is the process by which living organisms maintains constant internal environment. Maintaining homeostasis is very important because the survival of the living organism depend on it. In order to maintain homeostasis, the amount of wastes, nutrients and water that is in an organism must be controlled and maintained at optimum level.
2. A.
An organism that can not maintain an homeostasis will die. This is because, lack of homeostasis will disrupt the biochemical reactions which sustains the life activities of the organism and once the biochemical reactions that produce life energy can no longer take place the organism will die.
3. A.
For both unicellular and multi cellular organisms, when they are exposed to water containing no salt, much of the water will move into their cells. This happened because, the level of salt in the interior of the living cells is higher and so the water will move from the medium which has no salt to the inside to the cell where there is salt. This process is known as osmosis. In osmosis water move through a semi permeable membrane from the region of low salt concentration level to the region of higher salt level concentration.
4. D.
Cells in living organisms are able to maintain homeostasis by specializing in specific functions and by working together in cooperatively. Each cell has its own functions which it performs; in the process of its duty, it communicates with other cells which also help it in order to achieve common goals, which is maintenance of homeostasis within the cell.
