Match the following:
part a:
1. exercise that requires the use of oxygen to produce energy
2. exercise that does not require the use of oxygen to metabolize energy
3. amount of time needed to perform an exercise
4. a product of anaerobic exercise
5. how often an exercise is performed
6. an energy molecule produced when oxygen reacts with glucose
7. type of exercise
8. level of effort needed to perform an exercise
part b:
a. lactic acid
b. anaerobic
c. aerobic
d. frequency
e. intensity
f. duration
g. adenosine triphosphate
h. mode

1. is c = aerobic, 2. is b = anaerobic, 3. is f = duration, 4. is a = lactic acid, 5. is d = frequency, 6. is g = adenosine triphosphate, 7.  is h = mode, 8. is e = intensity.

Explanation:

1. is c = aerobic because this word means that 'air' or oxygen is involved thus processes only occur in the presence of O₂.

2. is b = anaerobic is the opposite of aerobic therefore these processes do not need oxygen to happen.

3. is f = duration is the length of time needed to undergo or undertake a specific task.

4. is a = lactic acid is thought to be a 'waste' product of anaerobic metabolic processes but it can be utilized to be made useful.

5. is d = frequency is how many times in a specified interval the exercise is performed.

6. is g = adenosine triphosphate or for short, ATP, is the product of when glucose and oxygen react in the mitochondria.

7.  is h = mode is the specific category of exercise one performs ie., swimming, running, badminton etc.

8. is e = intensity is the degree of emphasis you put into trying an exercise.

i think your answer is c. measurement system in which the medication dosage was calculated.
