Cell Cycle
Mitosis
Meiosis
Scientific Method

This phase of the cell cycle is where the cell grows and performs normal functions before DNA replication.

Mitosis is involved in which type of reproduction?
Asexual
100
Meiosis is involved in which type of reproduction?
Sexual
100
Replicating an experiment by other scientists helps validate results and reduces this
Error
200
During this phase, DNA is replicated
S phase
200
The final result of mitosis is 2 of these cells with the same number of chromosomes as the parent
Diploid
200
The final result of meiosis is four of these cells with half the number of chromosomes as the parent
Haploid

If a scientist’s results do not support the hypothesis, this is the next best step?
Repeat the experiment
300
This checkpoint ensures that all chromosomes are properly attached to spindle fibers before division.
Metaphase checkpoint
300
Please draw anaphase
300
Crossing over during this phase of meiosis increases genetic diversity
Prophase l

Students test whether the pH of water affects the activity of the enzyme catalase. Which represents a correctly designed experiment?
A. They change both pH and temperature to measure combined effects
B. They test several pH values but use different amounts of catalase for each trial
C. They keep temperature and enzyme amount constant while changing pH
D. They use only one pH level and measure the reaction once

The average time for one complete cycle to happen is 24 hours in normal human skin cells. If a mutation occurs in a gene that regulates cell division, what difference would they expect to see in cancerous skin cells?
A. Cancerous skin cells will not go through interphase.
B. Cancerous skin cells will skip the S phase.
C. Cancerous skin cells will complete the cell cycle faster, creating more cells.
D. Cancerous skin cells will undergo programmed cell death more frequently.

A student records the reaction times of classmates before and after drinking an energy drink. Which of the following is the DEPENDENT variable?
A. The brand of energy drink
B. The amount of time it takes to react
C. The size of the drink
D. The number of students tested

Mutations along the cell cycle can lead to cancerous tumors, what are two causes for these tumors?
Uncontrolled cell division or uncontrolled cell death
500
What stage does the error occur in?

A biology class tests whether cold temperature slows yeast fermentation. Their results vary widely. Which modification would MOST increase the experiment’s RELIABILITY?
A. Use only one yeast sample to avoid variation
B. Repeat each temperature test at least three times
C. Change the amount of yeast used to speed up the reaction
D. Test a wider range of temperatures instead of repeating trials
B
