Answer:
C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
Explanation:
Acceleration is defined as the rate of change of velocity per unit of time and velocity is defined as the speed of something in a given direction. The car is on a circular track, so it is constantly changing direction and therefore is constantly changing in velocity and accelerating. With this, we can eliminate choices A, B, and D since they either state that the car is not accelerating or not changing in velocity, leaving us with choice C) Acceleration is the change in velocity so the car is experiencing a change in velocity and it is accelerating.
please lmk if i made any mistakes, hope this helps you :)
Answer:
Option B, increasing the number and size of mitochondria
Explanation:
Mitochondria (power house of a cell) produce energy. When no exercise is done, the productivity of mitochondria reduces but it increases with regular exercise. In fact aerobic training helps mitochondria in making more energy by enhancing its efficiency. With one cycle of exercise, mitochondria produce 32 ATPs. Aerobic exercise allows more of oxygen to get to the muscle cells, the faster it happens the more energy is produced
Hence, option B is correct
