Why is it important to come up with a plan for how to respond to negative peer pressure before the situation happens?


a) Because it is very likely you will face these situations in the future

b) Since you probably won’t face peer pressure, it is not important to plan ahead

Answers

i think A this is because peer pressure happens very often and having a plan definitely helps

Answer:

a. Because it is very likely you will face these situations in the future.

Explanation:

"Peer pressure" refers to the effect that peers or friends have on an individual. This could be both "positive" and "negative." When children/teens start forming a set of friends, they are most likely to put influences on each other. Being part of a group will most likely result to a person trying to do something that is acceptable in the group.

For example, if the person's social circle are into smoking, then the individual will most likely do it. This is what you call negative peer pressure. Since this is very common around the world and kids will later grow up and find their social circles, it is very important to teach them on how to come up with a plan on how they should respond to negative peer pressure.

The body system pictured is primarily responsible for-







protecting and defending the body against germs that have entered the body


coordinating body functions using electrical messages


Regulating body functions using chemicals called hormones


transporting oxygen, carbon dioxide, nutrients, wastes, hormones, and other materials

Answers

Answer:

The body system described in the image is the nervous system, which is primarily responsible for coordinating body functions using electrical messages.

Explanation:

The nervous system is connected by nerves to each and every structure and organ, in order to control their functions. This occurs because of the connection between the central (CNS) and peripheral nervous systems.

The neuron is the functional base of the nervous system, and is responsible for the transmission of information in the form of electrical signals, called nerve impulses.

The transmission of nerve impulses occurs through the joint action of receptors, nerves, integration centers and effectors.The information that goes from the periphery to the CNS goes by afferent pathway, while from the CNS to the periphery it travels by efferent pathway.

The other options are not correct because:

Protecting and defending the body against germs that have entered the body  is function of Immune system Regulating body functions using chemicals called hormones  is function of endocrine system. Transporting oxygen, carbon dioxide, nutrients, wastes, hormones, and other materials is a function related to circulatory system.
