Answer:
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. ... Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
Explanation:
Answer:
1. The pathway of a red blood cell from the right ventricle to the brain is:
<em>Right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → artery aorta → arterial vessels → brain
.</em>
2. The substance that forms hemoglobin in red blood cells when it passes through the lungs is oxyhemoglobin.
Explanation:
Red blood cells are structures present in the blood, whose function is to transport oxygen (O₂) and carbon dioxide (CO₂). This process requires travel throughout the body, through the blood vessels, and gas exchange at the pulmonary and tissue level.
1. A red blood cell in the right ventricle contains carbon dioxide and must pass to the lungs to be oxygenated. The route it takes from there includes Right ventricle (minor circulation) → pulmonary arteries → lungs → pulmonary veins → left atrium → left ventricle → (joining the major circulation) artery aorta → arterial vessels → brain
.
2. The red blood cell or erythrocyte contains a molecule, called hemoglobin, which has an iron core that allows it to bind to O₂ and CO₂ in order to transport them. The affinity for one molecule or another depends on the presence of a certain gas in a certain place.
When the red blood cell passes through the lungs, the concentration of O₂ is higher than CO₂, so the latter is released and O₂ binds to hemoglobin, a conjugation that is called oxyhemoglobin.
Answer:
Fact: a set of data or observations that have been shown to be accurate through multiple trials.
Hypothesis: a proposed explanation for an occurrence based on available data, observations, or evidence
Law: a well-supported explanation of all the evidence related to a natural phenomenon
Theory: a description of a natural phenomenon that is always observed to occur under specific conditions
hope this helps :) :D <3
