Answer:
5. 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.
Explanation:
The contraction of muscles occurs in the presence of Adenosine Triphosphate (ATP) because ATP supplies the muscles with the energy they require for contraction.
Muscles can undergo contraction Aerobically ( in the presence of oxygen) or Anaerobically ( in the absence of oxygen).
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because 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.
Crossing over, or recombination is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
Answer:
I think this is 2 because there would have been bigger predators in the ocean vs. a lake
The paramecium would not be able to get rid of excess water so the cell would burst.
FUNCTION OF THE CONTRACTILE VACUOLE:
- The contractile vacuole is an organelle present in protist organisms like paramecium, amoeba etc.
- The contractile vacuole functions to regulate water balance in the cells of organisms that they are found. Contractile vacuole performs this function by storing excess water and expelling the out of the cell.
- Hence, if a disease affected a paramecium's contractile vacuoles, stopping the normal functioning of the vacuoles, the paramecium would not be able to get rid of excess water so the cell would burst.
