1. How does the principle of conservation of mass relate to chemical reactions?

1 answer:

4 0

1. According to the law of conservation of mass, in an isolated system, mass is neither created nor destructed by the physical conversions or chemical reactions. It is on the basis of the law of conservation of mass that in a chemical reaction, the mass of the products must be equivalent to the mass of the reactants.

2. A chemical equation tells us about the phenomenon of conservation of mass, that is, atoms are neither created nor destroyed at the time of a chemical reaction. A balanced chemical equation tells us that which substances are the products and what substances are the reactants, and what proportion of each substance are taking part, as well as their association with each other, and the steps that take place at the time of a reaction.

<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.

Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.

What dangerous environmental side effect increases because of human produced carbon dioxide?

vladimir1956 [14]

For the answer to the question above, one of the side effects of carbon in the environment is the global warming or Climate change. The Carbon dioxide traps the heat of the sun from escaping the atmosphere. This results to increase in global temperature which causes the ocean water to evaporate than usual and creates super typhoons.

Fill in the following flowchart to show the pathway of a red blood cell as

Alla [95]

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.
