Is it true that some people have been kidnapped by aliens

This is not very likely.

What must happen before meiosis can begin

DNA doubles and produces sister chromatids before meiosis begins.

the chromosomes must replicate

What is the role of microfilaments in cell division

They pull the cell membrane in.

They Split The Cell During Cytokinesis.

Why did Mendel study such a large sample of pea plants to determine the probability of inheritance

The more samples you use, the closer your results will match probability.

Bacteria are organisms that reproduce asexually how is this better for them than reproducing sexually

bacteria are organisms that face changes all the time. if the change wipes out all the bacteria and leaves only one, sexual reproduction is a bad survival technique even if it mutates.

They can grow to larger Populations more quickly.

What would happen if crossing over didn't happen during meiosis in humans

If crossing over didn't happen during meiosis in humans, the haploid daughter cells would all have the same genes. The crossing over creates variation and causes each daughter cell to have slightly different genes.

What statement is true of the X chromosomes

Women have two of them.

How are meiosis and mitosis different

mitosis only has to do with celluar reproduction

meiosis has to do with sex cells reproducing
Mitosis creates new cells that are used for development, repair, asexual reproduction and growth. Meiosis creates cells in order for organisms to reproduce sexually.

Why did Mendel wanted to find out if the color of the seed of a pea plant affected the seed shape What experiment did he perform to test his idea

He tested seed color and shape at the same time.

APEX

Which best describes probability
