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.
Answer: Possession of Valves
Explanation: Veins possess valves which ensures that blood flows in only one direction. Valves helps blood to flow back to the heart against gravitational force.
Arteries don't have valves because the pressure originating from the heart is capable of causing the blood to flow in one direction.
Answer:
by hiding and never getting seen and staying cautious
Explanation:
Answer: B
Why? It is not A or D for many reasons but cell differentiation is used for very specific functions as cell determination is used for different embryonic functions. Based on the diagram I seems to me that it is not very specific so that’s why I think it’s B
(If it’s not be then is 100% C but B makes more sense)
Hope this helps
C) voltage gated sodium channels
have a great day!
