When the air pressure within the alveolar spaces falls below atmospheric pressure, air enters the lungs (inspiration), provided the larynx is open; when the air pressure within the alveoli exceeds atmospheric pressure, air is blown from the lungs (expiration).
Answer:
A.
Strength and usefulness of claims are evaluated through scientific argumentation
Explanation:
Answer:
The Answer is A.
Explanation:
This is correct because evolution is a change in the inherited traits of a population over many generations. While natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
That would be the nervous system.
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.
