Which of the following statements is true of imagined risks?
bija089 [108]
Let's go through the choices!

A. They're unaffected by positive self-talk.

Let's pretend you are scared of thunder. If you tell yourself, "I will not let thunder scare me; it will not hurt me," you will be less scared! So, A is not the answer.

B. They're harmless, because they're imaginary.

If you are scared of something, it can damage your mental health, which is not harmless. So, B is not the answer.

C. They're a kind of negative self-talk.

Being afraid of something is usually due to an overexaggeration in your mind. So, C is a good answer.

D. They're a kind of positive reinforcement.

Being scared is not positive. So, D is not the answer.

The answer is C!

Hope I helped! :)

Georgio is jogging barefoot along the beach when he suddenly steps on the sharp edge of a broken shell. He instantly feels pain
VashaNatasha [74]

Georgio is jogging barefoot along the beach when he suddenly steps on the sharp edge of a broken shell. He instantly feels pain due to the message carried to his brain by<u> dendrites.</u> He then slowly walks home with an achy foot. The message of the ache is carried by <u>neurons.</u>

<u></u>

The nervous system has electrical cells that are trained to transmit and receive messages. Through the use of electricity, people can communicate by transmitting messages to one another. This voltage is produced in neurons by the movement of charged ions. salt atoms with positive or negative charges that pass through the cell membranes and cross the cell's outer membrane. The neuron has dendrites, which are branches (like a tree) that receive messages, and an axon, which is a longer, more straightforward projection (like a tree trunk), that sends information. Synapses. Axon ends include the neuron communication junction, where vesicle fusion releases chemical signals. Neurotransmitters are the chemical messages that the nerve cell releases.
