Answer:
a.) kinetic energy from the mallet is transferred first to the orange ball and then to the purple ball.
Explanation:
It is not mechanical like in B, potential energy is not passed from ball to ball like in C, and it is not electromagnetic like in D. Therefore, it is A because the mallet hits(kinetic) the orange ball then the orange ball rolls(kinetic) into the purple ball so that the purple ball rolls(kinetic)
Glial cells. More specifically, it could be oligondenrocytes, astrocytes, ependymal cells, schwann cells, microglia, or satellite cells, because they are all types of Glial cells.
