How should Jason communicate his health concerns to his parents? He should tell his parents he does not feel well enough to go to school. He should describe all of his symptoms to his parents and ask to see a doctor. He should avoid worrying his parents and not tell them until he has been sick for seven days. He should tell his parents that he will see the school nurse if he does not feel better.

Answer is b

Explanation:

Jason should communicate his health concerns to his parents by describing all of his symptoms and asking to see a doctor. Therefore, option (A) is correct.

What is health?

Health is the state of physical, mental, and social well-being, not merely the absence of disease or infirmity.

It is important to be honest and open with parents about any health concerns, especially if they are affecting one's ability to attend school or perform daily activities.

By providing a clear description of his symptoms, Jason's parents can better understand the severity of his condition and make an informed decision about seeking medical attention. It is important to note that delaying medical care can sometimes result in further complications, so seeking help early on is often the best course of action.

Avoiding worrying his parents or waiting for seven days before notifying them of his illness could potentially worsen his condition and delay the necessary treatment. Likewise, relying solely on the school nurse may not be sufficient for addressing the underlying health concern. Therefore, it is best for Jason to be proactive and communicate his concerns openly and honestly with his parents

Which statement describes the MOST likely organ match?

A.the nearest sibling
B.a similar cadaver
C.an identical twin
D.either parent

Answers

Answer:

D. Either Parent.

Explanation:

This is simply the most realistic answer. Your parent's gave you everything they have. For example, they already gave you your eyes, your face, etc. They created you, therefore they will have the highest chance of matching your organs.

I hope that helped! Have a lovely day.

Answer:

The answer would be a Identical Twin. Identical Twins DNA matches almost-exactly the same, therefore they would most likely have the same organs or body parts. When having a organ transplant the best match would be a Identical Twin. When you are put into the world by one parent, your DNA doesn't match completely as close as a twin, that may be why you act differently or look different. If you were born a twin, no-matter how different/similar you are from your parents, at the end of the day you both  share the same body a good percent.

Describe in 2 paragraphs how the Reversibility Principle in Sports relates to your current workouts. If you believe none apply to you, tell me how you plan to incorporate one of the principles into your workouts.

Answers

Answer:

Reversibility means that an athlete can lose the effects of training when they stop, and can gain the effects when they begin to train again.

Detraining occurs within a relatively short time period after an athlete ceases to train. Performance reductions may occur in as little as two weeks or sooner.

In trained athletes, research indicates that detraining may result in greater losses in muscular power than strength. Strength losses are due to first to neural mechanisms, and next due to atrophy of muscles.

What is interesting is that strength levels after detraining are rarely lower than pre training levels, so training has a residual effect even when it is discontinued. But when the athlete returns to training, the rate of strength acquisition is high.
