Answer:
Earth's axis always points in the same direction. Because of this, the part of Earth that receives the most direct rays from the Sun changes as the Earth travels around the Sun. At the equinox, the Sun's rays shine most directly on the equator, and the Northern and Southern Hemispheres get the same amount of Sunlight.

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.
