Your heart normally beats 70 to 80 times a minute, but the rate changes depending on your activity level. When you exercise, your body needs more oxygen than when you remain still. Your heart automatically responds to these changing needs. When you need more oxygen, your heart beats faster to increase the flow of blood to your body.

Which of the following best summarizes the passage above?
A.
Your body needs a lot of oxygen when you exercise. That is why you breathe heavier when you are running or shooting hoops with friends.
B.
Your heart rate is dependent on your level of activity. Your heart beats faster when you are exercising and slower when you are still.
C.
Your heart usually beats about 70 to 80 times in one minute. That is more than one heart beat for each second. That is pretty fast!
D.
Your heart makes blood flow throughout your body. It also allows oxygen to move into your muscles, lungs, and even into your bloodstream.

Answers

Answer 1

Answer:

A correctly analyzes the passage I believe :)

Explanation:

Answer 2

Your body needs a lot of oxygen when you exercise. That is why you breathe heavier when you are running or shooting hoops with friends which best summarizes the passage above. The correct option is A.

How does oxygen affect heart rate?

The ambient concentration of fine particles was shown to be correlated with a reduction in oxygen saturation and an increase in pulse rate and heart rate variability. A heart rate increase may occur as a result of hypoxia or impairment of autonomic nerve cardiac regulation.

Your muscles require more oxygen when you exercise—roughly three times as much as they do when they are at rest. Your heart begins to beat more quickly in response to this requirement, which causes your pulse to increase. Your lungs are also absorbing more air, which accounts for your heavier breathing.

Thus, the ideal selection is option A.

Is technology ruining us ?

Answers

Answer:

Yes

Explanation:

When I think about it everything around us is technology and we only like to talk from the phone; for example I know someone that has a bf but they don't like to talk to each other in person only from the phone

Answer: Yes.

Explanation: Technology ruins us because people who used them 24/7 without a break, have seizures and other health problems. In fact, being a parent is hard because my kids are rather on the phone than doing other activities. Here are some reasons why technology ruins us.

1. Kids are on it all day.

2. We easily get distracted by them.

3. People have seizures if they play on it without a break.

If we limit how long we use our devices, technology won't be as bad as it is today. About 86.9% people had a seizure when playing on their devices all day. So, this is why technology is ruining our lives and us people too.

A. Globally, abortion claims 2 billion lives each year and has costs the world untold value in the loss of scientist, artists, educators, and others who may have contributed to the cause of humanity.

B. Abortion is a questionable practice, but may be a considered reasonable in cases where the life of the mother is threatened or incest is evident.

C. Abortion is senseless when adoption is a much better option for anyone in an unwanted pregnancy.

Answers

Answer:

The answer is D "Including dramatic elements, like dialogue and stage directions"

Explanation:

Shakespeare transforms Plutarch’s historical account by including dramatic elements, like dialogue and stage directions". Hence, option D is correct.

What did historian described about Plutarch?

Notwithstanding his rejection of their beliefs, Plutarch was a Platonist who was open to the Peripatetics' influence and even to Stoicism in some specifics. Only Epicureanism was completely rejected by him.

Plutarch seeks evidence for his interpretation in numerous Platonic dialogues because he believes that there is only one "Platonic view" about the origins of the world, the fundamental elements of reality, and the function of the soul in the creation of the world.

Plutarch frequently made grave factual mistakes and primarily depended on secondary sources. The idea that Greeks should cooperate with their Roman overlords was one of his key themes.

Thus, option D is correct.

B.) Concerned
C.) Generous

Answer:thrifty 100%

Explanation:

Believing that the boldfaced neutral word is "very careful," the word that should be used to give the sentence a positive connotation is: A.) Thrifty.

Sentences that have a positive connotation are those that sound good in the ears of the listener.

The usage of the phrase, "very careful," in the sentence above makes it seem like Jonathan was very stingy.

But the usage of the term, "thrifty" in the sentence will send the idea that Jonathan was smart and economical in his usage of funds.
