$$\text{Force} \propto \frac{1}{\text{Velocity}}$$

Question 1

Which of the following best describes the difference between haploid and diploid cells in mammals?

Accepted Answer

Haploid cells contain one set of chromosomes, while diploid cells contain two sets.

Question 2

During which phase of mitosis do sister chromatids separate and move toward opposite poles?

Accepted Answer

Anaphase

Question 3

Which of the following is a function of the spindle fibers during cell division?

Accepted Answer

They attach to centromeres and help separate chromosomes.

Question 4

A heterozygous individual for a gene with complete dominance will express which phenotype?

Accepted Answer

Only the dominant trait

Question 5

Which equation correctly represents the expected ratio of phenotypes in a monohybrid cross with complete dominance?

Accepted Answer

$$3:1$$

Question 6

If a cell has 8 chromosomes at the start of meiosis, how many chromosomes will each gamete have after meiosis II?

Accepted Answer

4

Question 7

Which of the following best explains independent assortment during meiosis?

Accepted Answer

Alleles of different genes separate independently during gamete formation.

Question 8

A mutation that changes a codon from UAU (tyrosine) to UAA (stop) is best described as which type of mutation?

Accepted Answer

Nonsense mutation

Question 9

Which tissue type is responsible for voluntary movement in the human body?

Accepted Answer

Skeletal muscle

Question 10

Which of the following structures is found at the center of a sarcomere and is essential for muscle contraction?

Accepted Answer

Myosin thick filaments

Question 11

Which equation best describes the relationship between force and velocity in parallel muscle fibers?

Accepted Answer

$$	ext{Force} \propto \frac{1}{	ext{Velocity}}$$

Question 12

Which of the following is a disadvantage of an exoskeleton compared to an endoskeleton?

Accepted Answer

Restricted growth due to the need for molting

Question 13

Which cell type is responsible for bone resorption during bone remodeling?

Accepted Answer

Osteoclasts

Question 14

In the Beadle-Tatum experiment, what was the main conclusion regarding genes and enzymes?

Accepted Answer

Each gene codes for a specific enzyme.

Question 15

Which of the following best describes the role of tRNA in translation?

Accepted Answer

tRNA carries amino acids to the ribosome and matches them to the mRNA codon.

Question 16

Which of the following is a real-world example of co-dominance in human genetics?

Accepted Answer

ABO blood type, where both A and B alleles are expressed

Question 17

Which equation represents the expected genotypic ratio in a dihybrid cross with independent assortment?

Accepted Answer

$$9:3:3:1$$

Question 18

Which of the following best explains why large mammals use less energy per unit mass than small mammals?

Accepted Answer

Large mammals have a lower surface area to volume ratio, reducing heat loss.

Question 19

Which of the following is a function of epithelial tissue in the human body?

Accepted Answer

Covering surfaces and providing protection

Question 20

A patient has a mutation in the gene coding for the enzyme RNA polymerase. Which process would be directly affected?

Accepted Answer
