Answer:
At the beginning, aerobic respiration is used by his legs to generate energy when there was still sufficient oxygen intake for energy to be generated via oxidative phosphorylation.
Towards the end of the ride, his legs are generating energy through anaerobic respiration due to insufficient oxygen intake to keep up with the energy requirement of his muscles as he cycles continuously. Through anaerobic respiration, pyruvate from glycolysis is converted to lactate by lactate dehydrogenase instead of being channelled to the mitochondria for oxidative phosphorylation. The accumulation of lactate in his muscles is what causes the pain in his leg. After he stops the activity, the pain would reduce as lactate is transported to the liver to be reconverted back into pyruvate.
The correct answer is D. the offspring can be tall or short
In a given cross, F1 pea plants are hybrid tall or heterozygous tall (Tt). If F1 plants are allowed to self-pollinate, as a result tall and short pea plants are formed in the ratio 3:1 respectively. This result obeys Mendel’s law of segregation which states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
The rabbits are related to the population of coyotes because they are both part of a food chain. The rabbit population went down in between 1995 and 2000. It affected coyotes because there food chain got all messed up.
The answer would be: <span>Vitamin C and iron
</span>
Whole milk has many differences of concentration when compared to the breast milk. Whole milk has higher calcium, sodium and protein. The imbalance of concentration is dangerous as it might not same as the baby nutritional needs. It also lack of severals nutrition like vitamin C and iron.
