Answer:
Founder effect.
Explanation:
The founder effect is a case of genetic drift in which a small population sample of a limited number of individuals is shed from a larger population, its gene pool carrying only a part of the genetic diversity represented in the source population. Thus, it is likely that the genetic destinies of the population of origin and of the new population are established in different ways. When a new generation has randomly distributed alleles, with a large enough sample size, we can expect that the gene pool of the new generation will more or less represent the gene pool of the previous generation.
The terminal conducting elements in the ventricular myocardium are The Purkinje fibres.
The Purkinje fibers are specialised conducting fibres which are composed of electrically excitable cells and those fibers are located in the inner ventricular walls of the heart.e Purkinje fibres conduct cardiac action potentials and allow the heart to create synchronized contractions of its ventricles.
Answer:
The correct answer is option B.
Explanation:
On seeing the question, it is clear that it is based upon the concept of semi-conservative theory for the replication of DNA. It is mentioned that when the bacteria were grown on N-15, the mass was 55 fg. Now, after two generations, the DNA would comprise N-14 and the mass of them will be 5.4 fg.
The average mass would be = 5.4 + 5.5 / 2 = 10.9 / 2 = 5.45 fg. The mass of the bacteria isolated from the culture would possibly contain both the masses. That is, the mass of DNA with N-14 only would be 5.4 fg, and the mass of DNA with both N-15 and N-14 would be the average, that is, 5.45 fg.
Glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.
<h3>
Pathway of cellular respiration</h3>
Glycolysis, the link reaction, the Krebs cycle and oxidative phosphorylation are the stages of glucose oxidation. Complete oxidation of one molecule of glucose results in the production of 38 molecules of ATP.
This process also results in the production of 38 molecules of water because the formation of phosphodiester bond between ADP and inorganic phosphate involves the splitting off of a molecule of water so we can conclude that glycolysis, the Krebs cycle and oxidative phosphorylation are the pathways of cellular respiration.
