The picture on the left is a picture of all the chromosomes in a cell. Is this cell diploid or haploid, and how can you tell?

• It is diploid because there are an even number of chromosomes.

• It is diploid because there are two of each chromosome.

• It is haploid because there are an odd number of chromosomes.

• It is haploid because there is only one of each chromosome.

Which phase of mitosis is represented by the photo on the left?

• prophase

• metaphase

• anaphase

• telophase

Which is not an example of asexual reproduction?

• If you cut off a starfish's ray, the ray will grow into a completely new starfish.

• Penicillium is a fungus that can reproduce by forming spores through mitotic cell division.

• Yeast cells can reproduce by budding.

• If a lizard loses its tail during a fight, it can grow a completely new tail.

Which is not a difference between mitosis and meiosis?

• Meiosis involves two divisions, but mitosis involves only one.

• Meiosis is used in sexual reproduction, but mitosis is used in asexual reproduction.

• Meiosis produces haploid cells, but mitosis produces diploid cells.

• Meiosis (and then fertilization) produces offspring that are identical to the parent, but mitosis produces offspring that are different from either parent.

A diploid donkey cell has 62 chromosomes. How many chromosomes would this cell have after mitosis and after meiosis?

• 62 after mitosis and 31 after meiosis

• 62 after mitosis and 62 after meiosis

• 31 after mitosis and 62 after meiosis

• 31 after mitosis and 31 after meiosis
