A student is labeling a diagram of mitosis. Which description should the student label as anaphase?

• The chromosomes separate and move along spindle fibers to opposite ends of the cell.

• The chromosomes, which were distinct and condensed, begin to spread out into a tangle of chromatin.

• The centromeres of the duplicated chromosomes line up across the center of the cell.

• The genetic material inside the nucleus condenses and the duplicated chromosomes become visible.

Some species are able to reproduce either sexually or asexually. What is a drawback of a population using asexual reproduction only?

• High genetic diversity puts the population at risk to environmental change.

• Low genetic diversity puts the population at risk to environmental change.

• High genetic diversity prevents the population from expanding its territory.

• Low genetic diversity prevents the population from expanding its territory.

A student is labeling a model of the cell cycle. Which substance(s) should the student label as regulating the cell cycle?

• chromosomes

• cyclins

• nutrients

• DNA

What is the purpose of DNA replication in the cell cycle?

• to replace old DNA

• to increase genetic diversity

• to have two copies of each chromosome

• to help the cell grow larger

What is taking place in the process shown?

• DNA replication

• cytoplasm division

• sexual reproduction

• cell growth

Which of the following is a difference between mitosis and meiosis that is supported by the model?

• In anaphase of mitosis, sister chromatids separate. In anaphase I of meiosis, homologous chromosomes separate.

• Anaphase of mitosis leads to four haploid cells. Anaphase I of meiosis leads to two diploid cells.

• Crossing-over occurs after anaphase of mitosis while crossing-over occurs before anaphase I of meiosis.

• Chromosomes are not replicated before a cell enters anaphase of mitosis. Chromosomes have replicated before a cell enters anaphase I of meiosis.
