Which of the following best describes the function of the spinal cord? A. It merges simple responses to stimuli and sends information to the brain. B. It merges motor responses to muscles and sends information to the brain. C. It merges sensory responses to fingers and sends information to the brain. D. It merges complex responses to internal stimuli and sends information to the brain.

A. It merges simple responses to stimuli and sends information to the brain.

Explanation:

The spinal cord is a part of the nervous system that consists of long bones called vertebrae found mostly at the back of organisms.

The Spinal cord helps in the relay of information from the sensory cells (cells of the sense organs) to the brain.

The spinal cord also helps in the control of reflexes in which the spinal cord is solely responsible for.

1. glaciers are melting

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
