Describe the route taken by oxygenated blood from the lungs to the body cells

Biology
1 answer:
vodka [1.7K]2 years ago
4 0

Answer:

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

OR

The blood becomes oxygenated in the lungs. Oxygenated blood leaves the lung via the pulmonary vein. Blood moves into the left ventricle. Blood is pumped into the aorta, which carries oxygenated blood around the body.

Which of the following best describes what happens to a cell's genetic material during the process of meiosis II?
balandron [24]

Answer:The answer is option A sister chromatids are separated from each other to form gametes.

Explanation:

Meiosis is a  type of cell division which produces 4 daughter cells with different genetic material. The ploidy number or set of chromosomes is reduced to half in the newly formed daughter cells.This process usually proceeds in two divisions-meiosis I and meiosis II with four stages in each division which are prophase, metaphase, anaphase and telophase.Sister chromatids separate from each other during anaphase II of meiosis II which produces four haploid gametes from two intermediate cells formed by meiosis I.Thus, sister chromatids are separated from each other to form gametes is the correct answer.

How would the cycle be different if there were no water on earth?
Luda [366]

Answer:

What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Explanation:

The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:

water.usgs.gov

water.usgs.gov

So what would happen if there were no condensation stage?

The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.

Without clouds, I foresee a few things happening:

From clouds come rain. With no clouds, there would be no rain.

Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.

Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.

And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
