Homework due tonight, !
list the four types pf stem cell, give an example of each type, and explain how much each type can differentiate.

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.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
