The missing part of the question is as follows:
Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
Answer:
1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.
Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.
2. The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.
Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.
3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:
Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.
Answer:
d. addition of short sections of new amino acid sequence.
Explanation:
Amino Acids don't really deal with controlling Enzymes. I hope this helps:)
Answer:
it is clearly the oxygen cycle
Answer:
The arrector pili muscles contract (piloerection) and lift the hair follicles upright. This makes the hairs stand on end, which acts as an insulating layer, trapping heat.
Answer:
B.
artificial selection
Explanation:
Artificial selection is often utilized in crop and animal farming to obtain favorable traits in organisms. Organisms with desirable traits are selected and crossed with each other. Since the selection is done by humans and not by natural processes, it is called artificial selection.
In the given case, the farmers select corn plants with large ears. The selected plants are crossed with each other so that the next generation has the maximum chances of producing large ears. Hence, artificial selection is used here.
