Answer:
As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level.
Explanation:
Thin air exerts less pressure than air at a lower altitude.
The branch of science that really lets us understand organisms better.
The frequency of alleles in a population that is in hardy-Weinberg equilibrium
A) changes in each successive generation
<u>B) is less important than the frequency of genotypes </u>
C) shows evidence of the process of natural selection
D) remains the same over several generations
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.
