The nervous system of a crab differs from that of vertebrates (mammals, birds, fish, etc.) in that it has a dorsal ganglion (brain) and a ventral ganglion. ... The ventral ganglion is located beneath the internal organs, between the legs.
Answer:
It is a trait highly influenced by environmental factors (i.e., it has low heritability)
Explanation:
In population genetics, heritability is a statistical measure to estimate the proportion of the phenotype variation of a given trait which can be explained by hereditable genetic factors. The heritability of a trait is influenced by environmental factors, genetic factors (e.g., allele frequencies, number of genes involved in trait variation, recombination rate, etc), and the interaction between genetic and environmental factors. A low heritability value suggests that most of the variation is not genetic (i.e., due to environmental factors), while a high heritability value suggests that almost all of the variability in a trait is due to genetic factors.

Rabbits, for instance, often suffer malocclusion, but hay, twigs, and other items can help to prevent the occurrence of malocclusion and other related dental issues.</span>
Answer:
Experiments provide evidence.
Explanation:
You do experiments to answer a question (ex. can plants survive without water?). You answer your experiment's driving question with evidence (ex. no, plants can't survive without water because the plants in our experiment died without water, while the ones that received water grew).

Answer:
Neurons are functional units of the nervous system. The neuron is divided into three main parts dendrite, cell body, and axon.
