Question

question: scientists are interested in stem cells because they ____. answer options: select one of four: are a great source of vitamin a, can predict evolution, can be used to replenish lost cells, manufacture antibiotics

Explanation:

Stem cells are undifferentiated cells that can differentiate into various cell types. They are not a source of vitamin A, cannot predict evolution, and do not manufacture antibiotics. Their key property is the ability to replenish lost or damaged cells (e.g., in tissue repair or regenerative medicine). So the correct option is the one about replenishing lost cells.

Answer:

can be used to replenish lost cells
