Answer:

(Choice B) 555 homologous pairs of chromosomes comprising a total of 202020 chromatids

Explanation:

Homologous chromosome are those two chromosomes which have same gene but different in shape and appearance. Chromatids are the identical copies of chromosome. Single chromosome splits into double number of chromatids. In 555 pairs, 101010 chromosomes are present so 101010 chromosomes splits into 202020 chromatids.

I neeed helppppppp <br><br> Chemical Weathering 5 facts about it
Lubov Fominskaja [6]

Answer:

5 Facts

Explanation:

1. When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.

2. In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.

3. While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.

4. Chemical weathering types can work separately, but they often work together to create landforms and break down minerals.

5.  Acid rain caused by pollution such as factory and car exhaust is another agent of chemical weathering.
