Why fossils are important and why sedimentary rocks have fossils?

Biology

Sedimentary rocks are 'built up' over time, and if something dies overtime, lets say an animal, it will get buried and minerals will fill it and it becomes a fossil. fossils are important because they tell us about the past and what is was like way back when.

Compare the number of eggs to the number of sperm that result from meiosis?
Molodets [167]

Answer:

In the result of meiosis, testes produce 4 small mature sperm while ovaries produce 1 large egg cell.

Explanation:

Meiosis produces gametes (sex cells). Sex cells are eggs in females and sperm in males.

In the female, ovaries produce four haploids (3 polar bodies and 1 immature egg) under meiotic division. Polar bodies die because of the unequal division of cytoplasm. The immature egg matures into a large ovum/egg every 28 days during the menstrual cycle that is able to fertilize.

In the male, meiosis occurs in testes that produce 4 spermatids that mature into 4 small sperms. Testes produce several hundred million sperms every day under meiosis. These sperms are able to fertilize.

Nevertheless, if we want to compare their numbers based on meiotic division, we would say that they will be in the same ratio (1:1) at the end of each meiosis cycle for males and females.

Who is Gregor johann Mendel?
qaws [65]
I’ll give you a short overview of what I know.

He was a scientist, biologist, and wrote many books. He was specifically known for creating the science of genetics.

Mendel was born in 1822 into a poor farming family and then died January of 1884. He was an Austrian monk who discovered the basic principles of hereditary through experiments in his very own garden!

I’m sorry. I don’t believe this defines him. You can’t really define anyone in this short of a paragraph. To really know him, I’d have to do deeper research.
As for now, I hope this helps out. This probably just scratches the surface of who he really was. Have a great night!

All my best,
~Brooke❤️
