The table below compares two types of respiration. Respiration Types
Type AType B
Carbon dioxide producedYesNo
Fermentation involvedNoYes

Which statement is correct about Type A and Type B respiration?
Type A respiration involves electron transport, but Type B respiration does not involve electron transport.
Type A respiration produces lactic acid, but Type B respiration does not produce lactic acid.
Type A respiration does not involve glycolysis, but Type B respiration involves glycolysis.
Type A respiration produces ATP, but Type B respiration does not produce ATP.

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
