1: There are four stages of meiosis including prophase, metaphase, anaphase, and telophase. In the prophase phase (first stage) the chromosomes becomes visible as paired chromatids. When this happens the nuclear envelope disappears. During metaphase (second stage) the chromosomes attach to the spindle fibers. Throughout anaphase (third phase) the chromosomes move to opposite sides of the spindle fibers. While in telophase (fourth stage) two nuclei form by chromosomes and chromatids moving to the opposite ends of the cell.

2: The cells that outcome from meiosis are haploid daughter cells.

3: Haploid.

4: The similarities of meiosis and mitosis are that they both outcome with daughter from a parent cell. Differences are that mitosis has one round of genetic separation and cellular division while meiosis has two. In meiosis it creates daughter cells that aren’t identical.

Sexual reproduction combines genetics from two parents while asexual reproduction have offspring exactly the same as the genetics of the parent.

Asexual reproduction has the advantage of quicker reproducing. Sexual reproduction have all different offspring that can adapt to many different environments.

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.
