How energy is conserved even though the amount of energy available

1 answer:

4 0

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

During which phase of meiosis does each of the following events occur?

lubasha [3.4K]

Answer:

(a) crossing over: Meiosis I, Recombination

(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II

Explanation:

Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.

Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.

Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.

kifflom [539]

Answer:

Algal blooms occur when algae multiply very quickly. Blooms can form in waters that are rich in the nutrients the algae need to grow, such as nitrogen, phosphorous, and iron. ... Blooms may become more frequent as the earth warms and the levels of nutrients in our waters increase.

LET'S CHECK

Daniel [21]

Answer:

4) The deoxygenated blood then travels through the veins and enters the right side of the heart.

1) The blood leaves the heart through the aorta.

2) The blood travels throughout the body via the arteries to the capillaries.

3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.

II.

2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.

1) The deoxygenated blood flows from the right side of the heart to go to the lungs.

3) The oxygenated blood then returns to the left side of the heart.
