All of the following are correct comparisons of anaerobic and aerobic respiration except

aerobic respiration occurs with oxygen and anaerobic respiration occurs without oxygen
more energy is produced as a product to be used by organisms in aerobic respiration than anaerobic
aerobic respiration is only done by animal cells but anaerobic is done by plant and animal cells
carbon dioxide is always produced by aerobic respiration but only sometimes by anaerobic respiration

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
