why do fat-soluble vitamins need to be consumed less frequently than water-soluble vitamins?

Answers

Answer:

While vitamins are essential nutrients our bodies require to function properly, many of us get what we need through our diet.

Water-soluble vitamins are those that are soluble in water. They are stored in small quantities and, therefore, it is necessary to ingest them daily. Fat-soluble vitamins, on the other hand, are those soluble in lipids.

What are fat-soluble and water-soluble vitamins?

“For fat-soluble substances to be absorbed, the presence of bile and pancreatic sulcus, in addition to lipids, is also necessary. They are vitamins A, D, E and K. The water-soluble vitamins are all the vitamins of the B complex and vitamin C.

With this information, we can conclude that water-soluble vitamins are those that are soluble in water. They are stored in small amounts and therefore it is necessary to eat them daily. Fat-soluble vitamins, on the other hand, are those soluble in lipids.

12. Why do you think that high blood pressure is called the "silent killer?"

Answers

Answer:

Explanation:

1. Blood pressure is the pressure of blood against the walls of blood vessels.

2. The heart pumping and arteries resisting the blood flow are the two physical forces that cause blood pressure.

3. Temperature, diet, emotional state, posture, and medications can affect blood pressure.

4. The unit of measurement used to measure blood pressure is millimeters of mercury/mmHg.

5. The instrument used to measure blood pressure is a sphygmomanometer.

6. Normal blood pressure for adults should be less than 120/80 mmHg. The normal range for systolic pressure should be less than 120, and the normal range for diastolic pressure should be less than 80.

7. Diastolic pressure is pressure when the heart rests between beats, while systolic pressure is the pressure at the peak of each heartbeat.

8. Prehypertension means that the blood pressure is higher than it should be, and is from 120/80mmHg to 139/89mmHg.

9. Hypertension is when one's blood pressure is 140/90mmHg or higher.

10. Kidney problems, hormonal disorders, and abnormalities of the aorta may increase blood pressure.

11. Because the pressure is higher, the heart has to pump harder to get blood through the circulatory system, and arteries must carry blood that moves under greater pressure.

12. High blood pressure is called the "silent killer" because people can live with it for years and have no symptoms.

Lean on Me Questions


7. Do you believe that some public schools receive more funding than others? If so, how do you think this happens? If not, why are some schools able to purchase things for their schools - while others are not?


8. Why do you think there is little public concern about schooling inequality? What changes would our society have to make to eliminate schooling inequality?


9. What impressions did you get about the teachers in this movie? What impressions did you have about the students in this movie? What impressions did you have about the parents in Lean on Me (especially Mrs. Barrett)?

Answers

Some public schools receive more funding than others, and this can occur for a variety of reasons, such as inequalities between states and municipalities that generate lower revenue and taxes for funding.

There is little public concern about inequality in education due to several variables such as the social factors that lead to this inequality, such as prejudices against students and schools in low-income areas.

To eliminate inequality in education, greater publicity and dissemination of information would be necessary to eliminate prejudice, instituting educational reforms that include and integrate students regardless of their social class.

The teachers in the film Lean on Me face constant challenges working in a school damaged by drugs and crime, where they are not protected from gang violence.

In the film, Ms. Barret is the mother of a student who has been thrown out of school, and is against the radical reform attitudes that the new principal is promoting in the education system.

Therefore, the film portrays the challenges of the faculty in dealing with issues in a school considered problematic, where there are problems with drugs and violence, low student interest and conflicts between parents.

The film shows that perhaps the best solution to deal with educational inequality is to generate reforms that improve infrastructure and instill a sense of appreciation and high esteem in students.
