How are mitosis and meiosis similar

they both produce new cells(apex)

they both have prophase and metaphase (anaphase)

They both involve duplicating chromosomes.

they both have simular steps.

Why did Mendel use pea plants in his experiments

They Self-fertilize. -Apex

What happens during interphase

the chromosomes are duplicated.

What is produced by meiosis

Reproductive cells-- egg or sperm cells--or produced by meiosis.

Which two DNA samples are the most similar

The question itself is not clear. Two cells that have just divided will have the MOST similar DNA. If we are talking about whole organisms or individuals, then clones would have the most similar DNA, similarly identical twins would have near identical DNA. Siblings have very similar DNA but not identical of course.

Why did mendel use pea plants in his experiment

They produce many offspring

How are tumor cells different from normal cells

Mitosis is not regulated in tumor cells. This can cause the rapid proliferation of a large number of non-functional cells, whose only actions are to divide into more cells.

Tumor cells multiply too quickly.

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.

An organism that reproduces sexually has a diploid number of 40 How many chromosomes will a gamete of this organism have

20

A plant can have either brown B or red b leaves Brown is the dominant trait If a plant has genotype bb which best describes the plant

Homozygous with brown leaves

A cactus can either have long needles L or short needles l A cactus grower crosses two cacti what is the result what is the phenotype ratio for the cross

3 long, 1 short

Which best describes probability

the likelihood that something will happen

A scientist wants to make a dna fingerprint and she used polymerase chain reaction and restriction enzymes what should her next step be

use restriction enzymes is the right answer for apex :)
