A nitrogenous base


A phosphate group


A five-carbon sugar


An amino acid

Question 2 (1 point)
Which of the following correctly describes a key difference between mitosis and meiosis?

Question 2 options:

Mitosis produces genetically identical daughter cells, whereas meiosis produces genetically diverse daughter cells due to independent assortment and crossing over


Mitosis occurs in germ cells, while meiosis occurs in somatic cells


Meiosis consists of a single round of division, while mitosis consists of two rounds of division


Mitosis leads to the production of haploid cells, while meiosis produces diploid cells

Which of the following enzymes is primarily responsible for synthesizing new DNA strands during DNA replication?

Question 3 options:

DNA helicase


DNA ligase


DNA polymerase


RNA primase

Question 4 (1 point)
Which of the following best describes the difference between gradualism and punctuated equilibrium in evolutionary theory?

Question 4 options:

Gradualism suggests that evolution occurs in rapid bursts, while punctuated equilibrium proposes that evolution is a slow, continuous process


Gradualism posits that species evolve through small incremental changes over long periods, whereas punctuated equilibrium suggests that species experience long periods of stability interrupted by brief episodes of rapid change.


Gradualism applies only to fossil evidence, while punctuated equilibrium applies to genetic evidence


Both gradualism and punctuated equilibrium argue that evolutionary change is constant and uniform across all species

Question 5 (1 point)
Which of the following statements best defines natural selection?

Question 5 options:

It is a process by individuals with favorable traits are more likely to survive and reproduce than those without these traits


It is the random change in allele frequencies in a population over time


It is the intentional breeding of organisms by humans to produce desirable traits


It is the movement of individuals into or out of a population, affecting genetic diversity
