2) Compare the types of neurons that synapse in the posterior, lateral, and anterior gray horns of the spinal cord.

Explanation:

The posterior horn is associated with the sensory nerve cells, the anterior horn is associated with the somatic motor neuron, and the lateral horn associated with the ANS ( autonomic nervous system).

Posterior horn:

Sensory neurons pass through the dorsal root ganglion after that the dorsal root and in the gray matter the neurons synapse to inter neurons in the posterior horn or may continue to the white matter and  then enter the spinal cord.

Anterior horn:

The motor portion of the nervous system has two parts; i) the somatic motor system and the ii) autonomic nervous system. The somatic motor neuron stimulates the skeletal muscle with stimulation. The somatic motor neuron cell bodies (part of verve cell) are in the anterior horn of the gray matter.

Lateral horn:  

The autonomic motor neuron send stimulation to smooth muscle, cardiac muscle, and glands etc. The cell bodies( part of nerve cell) of the autonomic motor neuron are in the lateral horn of the gray matter.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
