Most heterotrophs are chemoorganoheterotrophs<span> (or simply </span>organotrophs<span>) who utilize organic compounds both as a carbon source and an energy source. The term "heterotroph" very often refers to chemoorganoheterotrophs. Heterotrophs function as consumers in </span>food chains: they obtain organic carbon by eating autotrophs or other heterotrophs. <span>Most </span>opisthokonts<span> and </span>prokaryotes<span> are heterotrophic</span>
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.
E because i looked on quizlet idk look up the answer sorry
<span>Which organic compound, used for stored chemical energy, contains carbon, hydrogen, oxygen, and often phosphorous?
It would be Lipid</span>
