Accepted Answer

$$Q = m 	imes c 	imes \Delta T$$

Question 3

In the Surface Area to Volume Ratio lab, why do smaller cells tend to be more efficient at exchanging materials with their environment?

Accepted Answer

They have a higher surface area to volume ratio, allowing for more efficient diffusion.

Question 4

Which of the following best explains the results observed in the Osmosis & Diffusion Lab when a cell is placed in a hypertonic solution?

Accepted Answer

Water moves out of the cell, causing it to shrink.

Question 5

During the Enzyme Activity Lab, which variable is most likely to affect the rate of enzyme-catalyzed reactions?

Accepted Answer

Temperature

Question 6

In the Genetics Probability Lab, which formula would you use to predict the probability of a specific genotype in a monohybrid cross?

Accepted Answer

$$P = \frac{	ext{number of desired genotype}}{	ext{total number of possible genotypes}}$$

Question 7

Which lab activity would best help students understand the process of mitosis and its stages?

Accepted Answer

Time for Mitosis Lab

Question 8

In the Hardy-Weinberg Lab, which equation is used to calculate allele frequencies in a population?

Accepted Answer

$$p^2 + 2pq$$ + $$q^2 = 1$

Question 9

A student observes animal behavior in the Reaction Time lab. Which of the following best represents a controlled variable in this experiment?

Accepted Answer

The type of stimulus used to elicit a reaction

Question 10

During the Natural Selection Simulation lab, which factor would most likely increase the frequency of a beneficial allele in a population over time?

Accepted Answer

Question 11

In the Molecular Models Lab, students build models of biomolecules. Which type of bond is primarily responsible for the secondary structure of proteins?

Accepted Answer

Hydrogen bonds

Question 12

Which of the following is a direct application of the Cell Structure and Membrane Transport unit in medical science?

Accepted Answer

Question 13

In the Enzyme Simulations lab, students observe the effect of substrate concentration on reaction rate. Which graph best represents the relationship between substrate concentration and reaction rate for an enzyme-catalyzed reaction?

Accepted Answer

A hyperbolic curve that plateaus at high substrate concentrations

Question 14

During the Cladistics Lab, students construct phylogenetic trees. Which characteristic is most useful for determining evolutionary relationships?

Accepted Answer

Question 15

In the Karyotype Lab, a student observes a karyotype with three copies of chromosome 21. What condition does this indicate?

Accepted Answer

Down syndrome (Trisomy 21)

Question 16

Which of the following best explains why enzymes are specific to their substrates?

Accepted Answer

The active site of the enzyme has a unique shape that fits only specific substrates.

Question 17

In the Observing Mitosis lab, which stage of mitosis is characterized by the alignment of chromosomes along the center of the cell?

Accepted Answer

Metaphase

Question 18

Which equation would you use to calculate the surface area to volume ratio of a spherical cell with radius $$r$$?

Accepted Answer

$$\frac{4 \pi r^2$}{\frac{4}{3} \pi r^3$}$$

Question 19
