Question 1

Which of the following best describes the semi-conservative model of DNA replication?

Accepted Answer

Each new DNA molecule consists of one old strand and one new strand.

Question 2

During cellular respiration, which equation correctly represents the overall process?

Accepted Answer

$$\mathrm{C_6H_{12}O_6$} + 6\mathrm{O_2$} ightarrow 6\mathrm{CO_2$} + 6\mathrm{H_2O} + 	ext{energy}$$

Question 3

Which phase of mitosis is characterized by the alignment of chromosomes along the center of the cell?

Accepted Answer

Metaphase

Question 4

A cell is placed in a solution with a higher concentration of solutes than inside the cell. What type of transport will most likely occur, and what is the expected outcome?

Accepted Answer

Osmosis; water will move out of the cell, causing it to shrink.

Question 5

Which organelle is responsible for packaging and modifying proteins for secretion?

Accepted Answer

Golgi apparatus

Question 6

In photosynthesis, which equation represents the light-dependent reactions?

Accepted Answer

$$\mathrm{H_2O} + 	ext{light} ightarrow \mathrm{O_2$} + 	ext{ATP} + 	ext{NADPH}$$

Question 7

A patient has a genetic disorder caused by a mutation in the gene coding for a membrane transport protein. Which cellular process is most likely affected?

Accepted Answer

Facilitated diffusion

Question 8

Which of the following best describes the function of ribosomes in a cell?

Accepted Answer

Synthesize proteins from mRNA templates

Question 9

Which statement about Mendelian genetics is correct?

Accepted Answer

Heterozygous individuals express the dominant trait if the trait is dominant.

Question 10

Which of the following is NOT a function of the cell membrane?

Accepted Answer

Synthesizing proteins

Question 11

Which of the following best explains why enzymes are essential for metabolism?

Accepted Answer

They decrease the activation energy required for reactions.

Question 12

A scientist observes that a plant cell placed in pure water swells but does not burst. Which cellular structure is responsible for preventing the cell from bursting?

Accepted Answer

Cell wall

Question 13

Which of the following is a correct sequence of steps in the scientific method?

Accepted Answer

Observation → Question → Hypothesis → Experiment → Analyze Data → Conclusion

Question 14

Which of the following molecules is a nucleic acid involved in transmitting genetic information?

Accepted Answer

RNA

Question 15

Which process is responsible for moving large particles out of a cell?

Accepted Answer

Exocytosis

Question 16

Which of the following best describes the role of mitochondria in eukaryotic cells?

Accepted Answer

Site of cellular respiration and ATP production

Question 17

During meiosis, how many unique haploid cells are produced from one diploid cell?

Accepted Answer

Four

Question 18

Which of the following bonds is the strongest in biological molecules?

Accepted Answer

Covalent bond

Question 19

A mutation changes the base sequence from A-T to G-C in a DNA molecule. What type of mutation is this?

Accepted Answer

Substitution

Question 20

Which of the following best describes the relationship between genotype and phenotype?

Accepted Answer

Genotype is the genetic makeup; phenotype is the physical expression of a trait.
