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.
D. it is safer because no radiation is used
Your skin starts going through some changes after 24 hours <span>Nature is very efficient at breaking down human corpses. When you die your heart stops pumping blood around your body, thus depriving your cells of oxygen, which rapidly begin to die. Decomposing starts almost immediately, with the skin going through several changes in colour as the blood stops circulating leaving the body an ashen color. However different cells die at different rates. For example, brain cells die within a few minutes, whilst skin cells can survive over 24 hours after death. Soon after death rigor mortis occurs, which is caused by a complex chemical reaction (involving lactic acid and myosin), which forms a gel like substance which creates the body's stiffness. Rigor mortis lasts approximately 24 hours (depending upon ambient temperature). </span>
