Which structure of the nervous system carries action potential in the direction of a synapse?

A. Cell body

B. Axon

C. Neuron

D. Myelin

Answer Explanation:

Axons carry action potential in the direction of synapses. Axons are the long, fiber-like structures that carry information from neurons. Electrical impulses travel along the body of the axons, some of which are up to a foot long.

A neuron is a type of cell that is responsible for sending information throughout the body. There are several types of neurons, including muscle neurons, which respond to instructions for movement; sensory neurons, which transmit information about the external world; and interneurons, which relay messages between neurons. Myelin is a fat that coats the nerves and ensures the accurate transmission of information in the nervous system.

Therefore, the Correct Answer is B.

Q #1: What is the typical way a solid would turn to a liquid and then to a gas?

A. Vaporizing, then melting

B. Melting, then freezing

C. Vaporizing, then freezing

D. Melting, then vaporizing

Answer Explanation

A solid turns into a liquid by melting, and a liquid turns into gas by vaporization.
Q #2: Which of the following answers shows CH4 +2O2=CO2 +H2O as balanced?

A. CH4 + 2O2 = 2CO2 + 2H2O

B. 2CH4 + 4O2 = 2CO2 + H2O

C. 2CH4 + O2 = 2CO2 + H2O

D. CH4 + 2O2 = CO2 + 2H2O

Answer Explanation

For the formula CH4 + 2O2 = CO2 + H2O to be balanced there must be an equal number of molecules on both the reactant and product sides. In this case, for the formula to be balanced, a coefficient of a 2 needs to be placed in front of the O2 and the H2O molecules. This would make both the reactant and product sides have one carbon, four hydrogens, and four oxygens
