Two main types of projections extend from the cell body of a neuron. receive inputs from other neurons, while send information to other neurons.

Dendrites

Axons

Explanation:

Dendrites and axons are the two main types of extensions that come out of the soma of a neuron. Dendrites are relatively smaller in size than exons and have receptors for neurotransmitters on their surfaces. At the synapse, the receptors of dendrites of postsynaptic neurons serve as a binding site for neurotransmitters that carry the electrical impulses from the axon of the presynaptic neurons. The axons serve as information from the cell body towards the dendrites of other neurons. Therefore, dendrites serve as reception zone of a neuron.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

the correct option is option d
