Answer:
the object that affects gravity is call gravinaltational force which acts on the way human stay on earth
Explanation:
They provide the immune system with "memory" against previously encountered pathogens.
T memory cells are necessary for protective immunity against invading pathogens
The denaturation step in the polymerase chain reaction will be affected. As a result the DNA strands will not unwind and the DNA will not become single stranded.
<u>Explanation:</u><u>
</u>
Polymerase chain reaction is used to synthesize multiple copies of DNA. The technique in molecular biology uses thermal cycling which involves steps of heating and cooling. There are three important steps in PCR.
Nucleic acid denaturation is the first step. In this step the DNA is heated to about 90°c and this causes the denaturation of the DNA. Two strands of DNA get separated. The second step is annealing in which the strands are cooled to 55°c.
During annealing the primers stick to the complementary sites on the DNA to facilitate its replication. The third step is extension in which the temperature of the mixture is raised to 72°c. The tag polymerase will start working on the DNA strands and replicate them.
If the denaturation step is not performed the speration of double stranded DNA into single strands won’t take place.
Answer;
-Glycolysis
Glycolysis is common to both fermentation and cellular respiration.
Explanation;
Glycolysis is a universal process that is common to both cellular respiration and fermentation or anaerobic respiration.
- Fermentation and cellular respiration are similar in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.
-Fermentation and cellular respiration are different because, fermentation does not require oxygen but cellular respiration requires the presence of oxygen, and also water molecules are not produced during fermentation but are produced during cellular respiration.
