All of the following are problems that growth causes for cells EXCEPT

An advantage of sexual reproduction over asexual reproduction is that sexual reproduction

Which is an advantage of having a cell’s DNA bundled into chromosomes.

A multicellular organism begins life as a single cell—a fertilized egg with a complete set of chromosomes. The picture in Figure 10–2 above shows how the cell divides to become two cells, then four cells, eight cells, and so on. Which of the following statements best describes what happens during this process?

Which pair includes a phase of the cell cycle and a cellular process that occurs during that phase?

In Figure 10–4, what role does structure A play in mitosis?

The first phase of mitosis is called

Which of the following represents the phases of mitosis in their proper sequence?

The two main stages of cell division are called

During normal mitotic cell division, a parent cell that has four chromosomes will produce two daughter cells, each containing

Some cells form a cell plate during cytokinesis. Which of the following is true of the cells in Figure 10–6 above?

When cells are grown in a laboratory, which of the following is a factor that can stop normal cells from dividing?

Cells grown in a petri dish tend to divide until they form a thin layer covering the bottom of the dish. If cells are removed from the middle of the dish, the cells bordering the open space will begin dividing until they have filled the empty space. What does this experiment show?

Which of the following explains why normal cells grown in a petri dish tend to stop growing once they have covered the bottom of the dish?

In eukaryotic cells, the timing of the cell cycle is regulated by

Cyclins are a family of closely related proteins that

Which of the following are external regulators of the cell cycle?

Cancer is a disorder in which some cells have lost the ability to control their

As a cell’s size increases, its ratio of surface area to volume increases.

The smaller a cell is, the more difficult it is for the cell to move enough nutrients and wastes across its cell membrane to maintain its normal functions.

Surface area tends to grow faster than volume.

Mitosis is a form of sexual reproduction, because the daughter cells that form are identical to the parent cell.

The structure shown in Figure 10–5 is a replicated chromosome.

Most of a cell’s growth takes place during the G2 phase of the cell cycle.

In eukaryotes, the spindle breaks down during prophase and re-forms during telophase.

Typically, the longest phase of mitosis is metaphase.

The cell shown in step E in Figure 10-7 above is undergoing telophase.

During cytokinesis, a cell undergoing cell division finally splits into two daughter cells.

One difference between cyclins and growth factors is that each cell produces its own cyclins, but growth factors are signals that can be sent from one cell to another.

Cancer is a disorder in which some of the body’s cells lose the ability to control growth and division.

A single-celled organism would not be expected to undergo cell differentiation.

Stem cells taken from embryos are totipotent.

People opposed to stem cell research argue that it is unethical to collect embryonic stem cells because it usually preserves an embryo.

____________ stem cells are referred to as pluripotent.

During ____________________ reproduction, cells can produce genetically different offspring.

During ____________________ reproduction, cells produce genetically identical offspring.

Adult stem cells are referred to as ______________ and can only develop into limited types of cells.

Cell division occurs in two main stages, the first of which is called _________________________.

The phase of mitosis shown in step D in the Figure 10–7 above is called ____________________.

Look at Figure 10–8. Once structure A has completely formed, another phase of the cell cycle will start. This phase will be called ___________________.

The structure labeled A in Figure 10–8 is called the _________________________.

If a scientist counts 20 centromeres in a somatic cell. What is the diploid number of that organism?

This is a somatic cell directly after cytokinesis, what is the diploid number of this organism.

The process shown in Figure 10–8 occurs only in ____________________ cells that are going through cytokinesis.

During normal development, the cells between toes and fingers die by ____________________, a process of programmed cell death.

A doctor might treat a patient with cancer by giving the patient ____________________, which are drugs that can kill cells that are rapidly dividing.

Stem cells are unique because they have not yet completed the process of _______________ and become a distinct type of cell.

Harvesting ____________________ stem cells from a willing donor is not as controversial as harvesting techniques that involve the destruction of an embryo.

A zygote is referred to as _____________ because it has the ability to become any cell in the body.
