Which of the following explains the process that is illustrated in the model?
The model shows mitosis since it begins with a diploid cell and results in 2 diploid cells.
The model shows meiosis since it begins with a diploid cell and results in 2 diploid cells.
The model shows mitosis since it begins with a diploid cell and results in 2 haploid cells.
The model shows meiosis since it begins with a diploid cell and results in 2 haploid cells.
Sexual reproduction requires more energy and resources; however, most complex organisms reproduce sexually. What advantage does sexual reproduction give these organisms?
It is a fast process.
It results in more offspring.
It increases genetic diversity.
It requires time to find a mate.

The main difference between mitosis and meiosis is that…
DNA replicates during mitosis, but not during meiosis.
Mitosis makes genetically identical copies, meiosis does not.
Sister chromatids separate in mitosis, but not during meiosis.
Mitosis increases chromosome number in each cell while meiosis decreases it.
The process of mitosis ensures that....
DNA is replicated without error.
Cells will divide in the correct time.
Each new cell is genetically different than the parent cell.
Each new cell receives the correct number of chromosomes.

The model shows meiosis since it begins with a diploid cell and results in 4 diploid cells.
The model shows mitosis since it begins with a diploid cell and results in 4 haploid cells.
The model shows meiosis since it begins with a diploid cell and results in 4 haploid cells.
Which of the following explains the process that is illustrated in the model?
The model shows binary fission, a process of sexual reproduction, that forms two cells.
The model shows binary fission, a process of sexual reproduction, that forms four cells.
The model shows binary fission, a process of asexual reproduction, that forms two cells.
The model shows binary fission, a process of asexual reproduction, that forms four cells.
A snail has 24 chromosomes in each of its somatic cells. How does the cell cycle function to maintain this number of chromosomes?
Chromosomes are replicated in mitosis so the daughter cells each have 12 chromosomes.
Chromosomes are replicated in mitosis so the daughter cells each have 24 chromosomes.
Chromosomes are replicated in interphase so the daughter cells each have 12 chromosomes.
Chromosomes are replicated in interphase so the daughter cells each have 24 chromosomes.
Which statements are true of mitosis? CHOOSE TWO ANSWERS!
The offspring will be genetically identical to each other.
The offspring will be genetically identical to the parents.
The offspring will be genetically like both parents, but identical to neither parent.
The offspring will have a different number of chromosomes than either of the parents.
