Answer:
Hello!
7. A totipotent stem cell is a cell capable of differentiating into any cell required by the body.
A pluripotent stem cell can differentiate into any body cell but it is not required for the growth and development of the embryo.
Multipotent stem cells can differentiate into any cell in a specific cell lineage. For example, a red blood cell or white blood cell.
An oligopotent stem cell can differentiate into one of a specific cell type.
A unipotent cell is fully differentiated and specialized and can only produce more of its own cell type.
5. True. Tissues are a group of cells with the same structure and function.
Explanation:
Stem Cells:
A stem cell is an undifferentiated cell that has the capacity to differentiate into any cell of the body under specific conditions.
- Totipotent stem cells are the first embryonic cells produced by the division of the zygote. They can differentiate into any cell required for development.
- The embryonic cells formed through the division of the zygote are pluripotent cells.
NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.
<h3>What is nicotinamnde adenine dinucleotide?</h3>
The nicotinamnde adenine dinucleotide (NAD) is a coenzyme used in the transport electron chain of the cellular respiration.
The movement of electrons is coupled to a proton gradient in order to generate ATP, the energy coin of the cell.
In conclusion, NADH and FADF2 are the reduced forms of the nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD) coenzymes.
