Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends
Travka [436]

Answer:

Santi is walking barefoot through his yard when he steps on a sharp rock. The skin on the bottom of his foot sends  this information through a(n)  <em>sensory</em> neuron to his CNS. A(n) <em>interneuron</em> picks up  this information and carries it to <em>motor neurons of the CNS</em>, which sends a signal to the muscles in his foot causing his  foot to pull away from the rock.

Explanation:

The scenarios discussed in the question is known as a reflex action. In this action, specific receptors detect specific stimuli. For example, pain in the barefoot due to steeping on a sharp rock was the stimuli. This stimulus was detected by the sensory neurons. The sensory neurons turned this information into a chemical signal which was transported by the interneurons to the motor neurons of the CNS. The CNS detected the signal and gave information for a response as a result of which Santi pulled back his feet.

BRAINLEST SUPER EZ QUESTION Why is ocean water considered a mixture but a cup of water is a pure substance?
devlian [24]

Answer:

Ocean water is a mixture! Salt and water together, makes salt water, since the salt dissolves in it.

Normal water in a cup, though, is a pure substance. Nothing is in it, and its purified, so it is not a mixture.

If it's more than one things, it's a mixture!

I hope this helps!
