During which phase of the cell cycle does DNA replication occur?

  • A. Interphase
  • B. Mitosis
  • C. Meiosis
  • D. Cytokinesis
Correct Answer: A

Rationale: Interphase is the phase of the cell cycle where the cell spends the majority of its time and is characterized by three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). DNA replication specifically occurs during the S phase of interphase. This is a crucial step as it ensures that each daughter cell produced during cell division receives an exact copy of the genetic material. Mitosis is responsible for the equal distribution of the replicated DNA to the daughter cells during cell division. Meiosis is a specialized cell division process for gamete production in sexually reproducing organisms, involving two rounds of division to generate haploid cells. Cytokinesis is the final step of the cell cycle, where the cytoplasm divides to complete the formation of two separate daughter cells following nuclear division.

What is the strongest evidence for evolution?

  • A. The fossil record
  • B. Comparative anatomy
  • C. Biogeography
  • D. All of the above
Correct Answer: D

Rationale: A) The fossil record provides evidence of how organisms have changed over time, showing transitional forms and the progression of species.
B) Comparative anatomy involves studying the similarities and differences in the structures of different species, which can reveal common ancestry and evolutionary relationships.
C) Biogeography examines the distribution of species around the world, which can be explained by evolution and continental drift.

By considering all of the above evidence together, scientists can build a comprehensive understanding of evolution and how species have changed and diversified over time.

Which of the following is an example of a zoonotic disease?

  • A. The common cold
  • B. Influenza (the flu)
  • C. Malaria
  • D. HIV/AIDS
Correct Answer: B

Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

Where in the cell are proteins modified, sorted, and packaged for transport?

  • A. Ribosomes
  • B. Golgi apparatus
  • C. Endoplasmic reticulum (ER)
  • D. Lysosomes
Correct Answer: B

Rationale: The Golgi apparatus is the cellular organelle responsible for modifying, sorting, and packaging proteins for transport within the cell or for secretion outside the cell. Ribosomes are not involved in modifying, sorting, or packaging proteins; they are responsible for protein synthesis. The endoplasmic reticulum (ER) is primarily involved in protein synthesis and folding, rather than modification and packaging for transport. Lysosomes function in breaking down cellular waste rather than modifying, sorting, or packaging proteins for transport.

Which of the following is NOT a function of the nervous system?

  • A. Detecting touch
  • B. Regulating body temperature
  • C. Producing insulin
  • D. Controlling muscle movement
Correct Answer: C

Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.

Which of the following is NOT a method of sterilization?

  • A. Autoclave
  • B. UV light
  • C. Chemical disinfectants
  • D. Boiling water
Correct Answer: D

Rationale: A) Autoclave: An autoclave is a method of sterilization that uses high pressure and steam to kill microorganisms, making it an effective way to sterilize equipment and materials.\nB) UV light: UV light is a method of sterilization that damages the DNA of microorganisms, preventing them from reproducing and causing infections.\nC) Chemical disinfectants: Chemical disinfectants are used to kill or inactivate microorganisms on surfaces, but they may not always achieve sterilization, which is the complete destruction of all microorganisms.\nD) Boiling water: Boiling water is a method of disinfection rather than sterilization. While boiling water can kill many microorganisms, it may not be effective against all types of bacteria, viruses, and spores, making it unsuitable for achieving sterilization.\n\nTherefore, the correct answer is D) Boiling water, as it is not a method of sterilization.
