Answer: The answer is C
Explanation:
Antibodies or otherwise called Immunoglobulin are special protein that are produced by certain lymphocytes which produces antibodies which can affect the invading bacteria or other foreign bodies called the antigens or other toxins in a number of ways . Certain antibodies known as agglutinins make bacteria harmless by causing them to clump together. The lysins dissolve the outer coats of bacteria, the antitoxin neutralize the toxin of bacteria while precipitins precipitate the toxin as insoluble and therefore , convert them to a harmless compound. Antibodies are always produced by the immune system.
Answer:
The main difference between Prokaryotic and Eukaryotic cell is that, eukaryotes contain membrane bound organelles like nucleus where as prokaryotes do not. The genetic material is present at the center and is called nucleoid in prokaryotes.
Explanation:
Example of prokaryotes include bacteria and archea bacteria. Examples of eukaryotes include plants and animals. Prokaryotes lack organelles such as mitochondria, endoplasmic resticulum and lysosomes which are present in eukaryotes. Both the groups contain ribosomes but its 70s ribosome in prokaryotes and 80s ribosomes in eukaryotes.
There should not be any changes in the gene pool.
In Hardy-Weinberg equilibrium, the gene pool should have a constant rate. The equilibrium can be achieved if there is no factor that favors one gene more than the others. Since the genes have the equal chance to survive and mating, the ratio of the gene pool should not change dramatically.
Following the treatment, the Fetal Stem Cells will travel throughout the body, detecting damaged cells and tissue and attempts to restore them. The Fetal Stem Cells can also stimulate existing normal cells and tissues to operate at a higher level of function, boosting the body’s own repair mechanisms to aid in the healing process. These highly adaptive cells then remain in the body, continually locating and repairing any damage they encounter.
Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
