Answer:
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.
