The motor portion of the autonomic nervous system (ans), sympathetic and parasympathetic, are characterized by a two-neuron chain. the pre-ganglionic nerve cell body is located in the and the postganglionic nerve cell body is located in

1. Cerebellar trunk or spinal cord

2. ganglia

Explanation:

The Autonomic Nervous System (ANS) is a motor function system for visceral organs, blood vessels and secretory glands. The ANS is divided into a sympathetic and parasympathetic nervous system, which consists of a motor pathway, composed of two neurons: pre-ganglionic and post-ganglionic.

The cell bodies of pre-ganglionic neurons are located in the cerebellar trunk or spinal cord. These neurons secrete mainly acetylcholine.

Postganglionic neurons, in turn, have their cell bodies located in the ganglia, and are responsible for sending unmyelinated axons (absence of the myelin sheath) and secreting norepinephrine.

i think its the first one

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.
