Answer:
d. lactic acid
Explanation:
pyruvic acid can be made from glucose through glycolysis.
Pyruvic acid supplies energy to living cells when oxygen is present (aerobic respiration), and when oxygen is absent ferments to produce lactic acid.
During vigorous exercise, there may be insufficient oxygen available to completely break down pyruvic acid for energy. As a result, the pyruvic acid is converted to lactic acid
A and c because I had the same problem and I picked a and it was a and c
Answer:
What Keene High school students are you reading about? And what scientist are you talking about? If you had given more information I would have helped.

Ans.
Diffusion is defined as a spontaneous movement of molecules to a region of low concentration from the region of high concentration of those molecules. It does not involve use of energy and is a passive process. Diffusion is slow process that gets affected by distance as higher distance shows lower rate of diffusion.
Thus, the correct answer is 'option a).'
