Answer:
D is the answer.
Explanation:
The deeper into Earth's crust, the higher the pressure that forms metamorphic rocks.
The Krebs cycle is a cycle that is after glycolysis which allows the cell to get more ATP and have more ATP efficiency than that of glycolysis itself or <span>fermentation and glycolysis. Infact, it makes the ATP effeciency about 20 times. </span>
Answer:
46
Explanation:
A human cell has 46 chromosomes, 23 from the sperm cell and 23 from the egg cell.
Answer:
The three main steps of PCR amplification are :
Denaturation
Annealing
Elongation
Explanation:
Polymerase Chain Reaction (PCR) can best be describes as a procedure to amplify or make copies of DNA fragments.
The basic steps involved for PCR are :
1. Denaturation
In this step, the two complementary strands of DNA are seperated by the usage of heat. The best temperature for this procedure is 95°C.
2. Annealing
After denaturation, each strand of DNA serves as a template foe building a new strand. During the process of annealing, the temperature is reduced so that the primers can attach to the DNA strands. The optimum for this depends on the nature of the primers but usually the most feasible temperature is 55°C.
3. Elongation
In this step, the DNA polymerase adds nucleotides to the primers attached to the templates. The optimum temperature For DNA polymerase to work is 72°C.
The hypothesis of Rodman and Mchenry's involves mainly in energetic efficiency moving between patches of forest, to the account for the success of the bipedal adaptation in early hominids.
Habitual bipedalism was not driven by the encephalization, but vice versa. Mchenry pointed out that the theories and origin of bipedalism has a significance and speculative, it is important because they are implicated in differentiation.
