Quick !

which type of neurons did scientists discover are involved in imitation?

a. the axon carries information through electrical impulses away from the cell body to the axon terminals and then to other neurons, muscles, or glands.
b. the axon contains the nucleus that controls all the activities of the cell.
c. the dendrites regulate the substances that go in and out of the cell.
d. the dendrites carry the electrical impulses from the signal receivers to the cell body.

Mirror neuron is a neuron that fires not only when an animal performs an action, but also when someone else perform the same action. It was discovered in experiments with macaque monkeys using an MRI (magnetic resonance imaging). In the experiment, if a monkey rips a piece of paper, mirror neuron is activated, as well as it is activated when the monkey sees or hears that someone else rip the piece of paper. 

Q2. On the photo, arrow shows D. The dendrites carry the electrical impulses from the signal receivers to the cell body.

The neuron consists of body, dendrites, and axon. Usually there is one axon and many dendrites per cell. Axon carries impulse from the cell body, while dendrites carry impulses to the cell body.

b. climate change will cause an increase in biodiversity of all ecosystems.
