Question

question 9 (2 points) which of the following statements is true of stem cells? they convert glial cells into neurons. they can develop into most types of human cells. they are produced by brain grafts. they can cause a neuron to transmit information even when it is polarized. question 10 (2 points) in the nervous system, glial cells provide support and nutritional benefits to neurons. handle majority of the information processing in the brain. serve as a substitute for afferent neurons. produce new neurons and replace old neurons.

Explanation:

For Question 9, stem cells are undifferentiated cells that have the potential to develop into most types of human cells. They don't convert glial cells into neurons, aren't produced by brain - grafts, and don't cause a polarized neuron to transmit information.
For Question 10, glial cells in the nervous system provide support and nutritional benefits to neurons. They don't handle most of the brain's information processing, aren't substitutes for afferent neurons, and don't produce new neurons to replace old ones.

Answer:

Question 9: They can develop into most types of human cells.
Question 10: provide support and nutritional benefits to neurons.
