consciousness is rooted in the midbrain
The answer is; glucose
It is a 6 carbon ring simple sugar and is the most abundant monosaccharide in the body. Its levels in the body are referred to as blood sugars. Larger carbohydrates consumed in the diet are broken down to glucose utilized in respiration (Glycolysis and Krebs cycles) to produce the energy required by the cells. Plants, on the other hand, manufacture carbohydrates in photosynthesis.
Answer - D
Gametes always have half the number of chromosomes compared to the somatic cells, hence an unfertilized egg would have half the chromosomes from the mother, and a fertilized egg will contain diploid number of chromosomes. Half of them from inherited from each of the two parents.
Question 1
The farther apart <span>two genes are located on a chromosome, </span>less likely they are to be inherited together
Question 2
Codominant alleles assort independently.
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.
