Hopefully these are correct
During the exercise period (10-15min) the blood lactic acid concentration increases to about 13.2 mmol/dL (same units as on graph) as the individual is having problems keeping up their aerobic respiration. After 15min, they stop exercising and the lactic acid concentration starts to return to normal as their body is able to take in enough oxygen and catches up with the excess lactic acid, metabolizing it into CO2 and H2O. The period between 15-20 min shows the fastest reduction in concentration.
Oxygen
Oxygen is the final electron acceptor, no part of the process - from the Krebs Cycle through the electron transport chain- can happen without oxygen. Aerobic respiration is complete
Answer:
False
Explanation:
The main cause of man-made erosion is agriculture, followed by construction and mining.
Where humans once used sticks and stones, they have since developed technology that dramatically accelerated the speed of erosio.
Hence, if human descions are to control the soil erosion then there will be a very big impact on living conditions.
