When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:

#Unit 1. Molecules and their Interaction Relevant to Biology

glycolysis does not occur to significant extent under aerobic conditions.
muscle is metabolically less active under aerobic than anaerobic conditions.
the lactic acid generated is rapidly incorporated into lipids under aerobic conditions.
under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.

#Unit 13. Methods in Biology

A bag has 13 red, 14 green and 15 black balls. The probability of getting exactly 2 blacks on pulling out 4 balls is P1. Now the number of each colour ball is doubled and 8 balls are pulled out.The probability of getting exactly 4 blacks is P2. Then
