Answer:c. Dendrite → cell body → axon hillock → axon
Explanation:a neuron has many cytoplasmic extensions called dendrites.the dentrites enter into the cell body at one end . the cell body also leads to axon at the other end, which extends toward another dentrite.axon hillock connect the axon to the cell body.
Impulses are usually transmitted along the neuron in one direction.
From the dendrites to the cell body,to the axon hillock and then to the axon.
Overproduction of offspring, inherited variation, and the struggle to survive.
So: b, d, and e
Most probably these scientists will do more studies and experiments in order to learn more about the subject. For example, if they compare plastic grocery bag with paper grocery bag it is important to investigate which one is a better resource use in the life cycles, which one is better for manufacturing or whether one of them can be reused. There are many questions about this issue.
