Choose one of these fictional teenagers: Underweight Ursula or Overweight Oscar. Pretending to be that teen, post a message describing at least two behaviors that have contributed to the weight problem. Respond to another student’s post, offering Ursula or Oscar at least two suggestions for improving those behaviors. Finally, wrap up your original post with a goal that Ursula or Oscar can set to work toward a healthy weight.

Answers

1. I'll pick Overweight Oscar. One behavior that has contributed to this weight problem is most likely because Oscar is not getting the right amount of exercise each day. Another reason is because he is eating unhealthy foods like a McDonald's burger or IN-N-OUT, junk food, basically, or drinking soft drinks.
2. One suggestion for Oscar is to start exercising daily. For about 20-30 minutes, he should do any desired exercise he wants. Or he can go outside a ride bikes or play things that improve your muscles and decrease your body fat. Another suggestion is to start eating healthier food. It'd be better to check the Nutrition Facts of any type of food he wants before buying it.
3. Oscar's goal is to exercise for about 20-30 minutes a day and to limit the amount of food he is eating. He should start eating healthier foods that doesn't have high fructose corn syrup or food coloring. Soft drinks are put to a limit, as well.

Endocrine glands are the ductless glands. A kid or teenager with gigantism, also known as pediatric acromegaly or pituitary gigantism, has high quantities of the growth hormone (GH) in their body, which leads them to develop exceptionally tall statures.

Which of the following BEST describes what alveoli are?A.

They are the smallest tubes in the respiratory system.


B.

They have a small amount of surface area.


C.

They are found on the end of bronchioles.


D.

They are comprised of millions of cells

Answers

Alveoli are found on the end of bronchioles which is option C.

Alveoli are small air sacs found within the lungs that resemble a cluster of grapes. These are also known as pulmonary alveoli. They primarily stimulate gas exchange.

What is the function of alveoli?

  • The alveoli are the final stage of the respiratory system, which begins when we inhale air via our mouth or nose.
  • The oxygen-rich air passes via the trachea and into one of the two lungs through the right or left bronchus.
  • Carbon dioxide molecules, produced as a byproduct of respiration, are diffused back to the alveolus and ejected from the body via the nose or mouth.
  • Because the diaphragmcontracts, creating negative pressure within the chest, alveoli expand during inhaling. Because the diaphragm relaxes during exhaling, the alveoli rebound (spring back).

Thus, we can conclude that option C is correct.
