Answer:
mtDNA is used, consider forensic laboratories to characterize bone remains and identify individuals who have other evidence
The disadvantage of using mtDNA in relation to nuclear DNA is that it does not identify individuals unambiguously, it only detects relationships between groups of individuals
Answer:
A
Explanation:
The correct answer would be that <u>the cell was submerged in a hypertonic solution.</u>
<em>A hypertonic solution is a solution with a higher concentration of solutes than that of the cytosol of a cell suspended in it. When a cell is suspended in a hypertonic solution, water moves osmotically from the cytosol to the hypertonic solution. This causes the cytoplasm to collapse and the cell becomes flaccid. </em>
The correct option is A.
First of all we could start by verifying the clinical history. We could review past health complications, as well as present diagnosis that might be conditioning the hydration. Look for signs or symptoms such as lightheadedness, variations on the input/output of fluids, altered mental accuracy, etc. Recent gut problems and other bowels' problems should also be reviewed. Current medication should also be considered.
From a physical examination point of view, there should be a checking of vital signs, and evaluation of orthostatic blood pressure and any considerable swallowing.
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.
