Answer:

The correct option is B) send chemical messages across small gaps between neurons.

Explanation:

Neurons are the cells that make up our nervous system. Although they are connected to each other, they do not maintain physical contact with each other. The nerve impulse travels through the neuron, and when it reaches its dendrites, it is transmitted to the next neuron through the synapse, which is produced through the exchange of chemical substances called neurotransmitters. Neurons communicate with each other through the small spaces (or small gaps) between them, in a process known as synaptic transmission (where synapses are the connections between neurons). This synapse requires neurotransmitters (for example dopamine or glutamate) for the transmission of the signal or message, which after being released will bind to specific receptors causing an ionic change by opening or closing a channel.

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions - Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream -Simple Diffusion

d)Involved with, but does not become a part of chemical reactions -Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process- Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.

BigorU [14]

Answer:

b

Explanation:
