Answer;
C. Multipotent
Explanation;
-Multipotent cells are those cells that can develop into more than one cell type, however, they are more limited than pluripotent cells. Adult stem cells and cord blood stem cells are considered multipotent.
Totipotent cells on the other hand, are those cells that can form all the cell types in a body, together with the extraembryonic, or placental cells. Embryonic cells are the only cells that are totipotent within the first couple of cell divisions after fertilization.
Pluripotent cells are those cells that give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.
Group 7A, the Halogens contain metalloids such as Astatine.
During fertilization, the encounter of gametes results in the fusion of their nuclei. The nucleus of the egg cell thus formed is therefore a mixture of the two nuclei.
So the parent will only give half of his chromosomes, so the child will have 50% of his chromosomes that resemble each of his parents.
Another factor that must be mentioned is the genetic recombination between the chromosomes that occurs during meiosis of the reproductive cells. Thus, this will give a heterogeneous chromosome resulting from recombination of the two chromosomes of each of its parents, and the child will have a unique combination chromosome but keeping the alleles of both parents.
Answer:
D.20,000
Explanation:
The Gross Annual Primary Productivity for the wetland ecosystem is the amount of carbon taken up by the aquatic producers through photosynthesis.
Given that: Net Annual Primary Producer is 8,000 kcal/m2 per year, and respiration by the aquatic producers is 12,000 kcal/m2 per year, using the formula NPP = GPP – Respiration, we can determine the Gross Annual Primary Productivity of the wetland ecosystem.
NNP = 8,000 kcal/m2
Respiration = 12,000 kcal/m2
GPP = x
8,000 = x – 12,000 (NPP = GPP – Respiration)
Solve for x:
x = 8,000 + 12,000
x = 20,000 kcal/m2 per year
GPP = 20,000 kcal/m2 per year
Photosynthesis occurs at the highest rate under the most intense light
