Gwen is investigating how exercise affects the rate at which she can squeeze a ball. after several minutes, she begins to experience muscle soreness and fatigue. she knows that this means her muscles are beginning to run out of oxygen. which process is likely causing the soreness in her muscle cells?
a. lactic acid fermentation
b. photosynthesis
c. alcohol fermentation
d. krebs cycle

Lactic acid fermentation.

Explanation:

During strenuous muscle activity the liver converts glucose or any other sugars into ATP, anaerobically. This causes oxygen debt, due to the accumulation of lactic acid and carbon dioxide, thats needs to be repaid after exercising.

After exercise the muscles uses oxygen to oxidise the high level of lactic acid, resulting in painful muscles.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
