Answer:
Totipotent - Able to differentiate into any type of cell of the human body or of the placenta. For example, fertilized egg cells and the cells from the egg’s first few divisions.
Pluripotent - From totipotent cells, able to differentiate into almost any type of cell of the human body. For example, blastocyst cells
Multi potent - Can develop into more than one type of cell, but more limited than pluripotent cells. For example adult stem cells and cord blood stem cells
Unipotent - Can only differentiate in a single lineage. Skin cells are the most abundant type of these.
Answer:
Because of their importance in development in all animal phyla
Answer: A. Nucleus
Explanation:
The DNA from Eukaryotic cells is stored inside the nucleus of the cell. The Nucleus is where all the genetic information is stored; also it is the place where the DNA is replicated during Mitosis or cell division. Just a curious fact, Mitochondria also have DNA on their interior.
In eukaryotic cells, all the genetic information, in other words, the DNA is found in the nucleus, where its arranged in chromosomes. Therefore, the answer is A).
In the other hand, in prokaryotic cells, it isn't inside any special structure. Instead, it's just dispersed through the cytoplasm.
