Question

1. stem cells are able to specialize into the unique cell types seen throughout the body, a process called dropdown. a fertilized egg cell is considered a dropdown stem cell because it can differentiate into any other cell type. adult stem cells, such as the cells found in bone marrow, are considered dropdown stem cells because they can differentiate into a limited set of different cell types.

Explanation:

1. The process by which stem cells specialize into unique cell types is called differentiation.
2. A fertilized egg cell is a totipotent stem cell because it can differentiate into any cell type (including placental cells).
3. Adult stem cells like those in bone marrow are multipotent because they can differentiate into a limited set of cell types (e.g., blood cells from bone marrow stem cells).

Answer:

1. differentiation
2. totipotent
3. multipotent
