Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.
Answer:
The correct answer is "cell lysis due to the effect of osmotic pressure".
Explanation:
The cell wall is a structure that brings protection from the outside world and also helps to maintain the cell's water balance. The cell wall prevents that the cells is exposed to a large amount of turgor pressure, making the cell turgid when it is under extremal conditions. Some antimicrobials, such as bacitracin, block cell wall synthesis which makes the cell unable to support turgor pressure, resulting in cell lysis due to the effect of osmotic pressure.
<span>A person who has rh- blood can develop rh agglutins through;
1. Pregnancy.
2. Transfusion.
3. Exposure to blood.
Agglutination is termed as clumping of particles. It is the process which occurs when an antigen is mixed with its corresponding antibody known as isoagglutinin.
When people are being given blood transfusion of wrong blood group then the antibodies will react incorrectly with the transfused blood group, then the erythrocytes clump up and stick together which causes them to agglutinate.</span>
The answer is B. Paleozoic
This era was the first era where insects, amphibians, and reptiles roamed the Earth.
Hope this helps!
Answer:
The nucleotide sequence of a corresponding DNA strand would be TCGAATTCG.
It can be explained with the help of complementary base-pairing nature of the DNA strands that is, the nucleotide bases of the two strands are complementary in nature.
The purines (adenine and guanine) always base-pair with pyrimidines (thymine and cytosine).
More specifically, adenine always base-pair with thymine with the help of two hydrogen bonds and guanine always base-pair with cytosine with the help of three hydrogen bonds.
