Answer:
C. Weight loss causes fat cells to shrink in size
b. a supportive network of friends
c. difficult school assignments
d. stressful jobs and activities
the correct answer is (B).
Regular participation in physical activity can increase life expectancy as exercise promotes health and makes our body healthy and strong, free from all diseases.
All-cause mortality is decreased by about 30% to 35% in physically active as compared to inactive subjects.
By participating regularly in education, you improve your health. Having a healthy heart can assist you to live longer and so as for you to take care of a healthy heart you want to eat right and compute cardio muscles.
Thus, physical activity promotes life by making our bodies free from all diseases.

Answer:
Post traumatic stress disorder
Explanation:
Post traumatic stress disorder (PTSD) is very commonly found in people who have experienced a severely traumatic event. This is commonly seen in war veterans as a result of traumatic events. Examples include seeing a family member die, or being a part of a terrible accident.
The brain often cannot recognize it as something that actually happened, so it stops the sufferer from functioning as a normal person in society, and sufferers often have to have special care.

B for 200W, A for lactate threshold, C for 250W lactate, B for lowest VO2max, A for energy increase 150W to 200W, C for highest VO2max.
Subject B expends the most kcal/min cycling at 200W, as their VO2 value (2600 ml/min) is the highest among the three subjects at this intensity. This indicates a higher energy expenditure. The VO2 values reflect the oxygen consumption during exercise and provide insights into energy utilization.
Subject A's higher blood lactate threshold is evident from their higher VO2 values at all exercise intensities. This suggests their ability to tolerate higher exercise intensities before lactate accumulation.
Subject C's highest blood lactate concentration at 250W signifies the onset of anaerobic metabolism, where lactate production surpasses its removal. This points to differences in aerobic capacity among the subjects.
Subject B's lowest VO2max (3800 ml/min) implies their comparatively lower maximal aerobic capacity. VO2max represents the maximum amount of oxygen an individual can use during intense exercise and is a key indicator of fitness.
Subject A's largest increase in energy expenditure from 150W to 200W indicates higher efficiency in utilizing energy sources during exercise progression.
Subject C's highest VO2max (3000 ml/min) showcases their superior aerobic fitness compared to the other subjects, emphasizing their maximal oxygen uptake capacity.

ANSWERS:
1. Which subject expends the most kcal/min cycling at 200W?
- A: 2800
- B: 2600
- C: 2500
The answer is A
2. Which subject has the highest blood lactate threshold?
This would be the subject who can maintain a higher VO2 at higher wattages without a significant drop.
- A's VO2 drops by 200 from 250W to 300W.
- B's VO2 doesn't drop from 250W to 300W.
- C's VO2 drops by 500 from 250W to 300W.
The answer is B.
3. Which subject has the highest blood lactate concentration at 250W?
This would be inferred from a significant drop in VO2 at the next higher wattage (300W).
- C has the most significant drop, so the answer is C.
4. Which subject has the lowest VO2max?
- A's highest VO2: 3900
- B's highest VO2: 3800
- C's highest VO2: 3500
The answer is C.
5. Which subject has the largest increase in energy expenditure going from 150W to 200W?
- A: 600 increase
- B: 700 increase
- C: 500 increase
The answer is B.
6. Which subject has the highest VO2max?
As mentioned in the answer to question 4, the answer is A with a VO2max of 3900.
