1. Which of the following is an example of aseptic technique?

Correct answer: A

Rationale: Rationale: Aseptic technique refers to practices that help prevent the introduction of harmful microorganisms into a sterile environment. Washing hands with soap and water before surgery is an essential component of aseptic technique as it helps reduce the number of microorganisms on the hands, decreasing the risk of introducing pathogens into the surgical site. Coughing into your elbow is a good hygiene practice to prevent the spread of respiratory infections but is not specifically related to aseptic technique. Sharing a stethoscope without cleaning can introduce microorganisms from one patient to another, compromising aseptic conditions. Leaving a wound dressing exposed can lead to contamination and infection, which is contrary to aseptic technique.

2. What does the term "colligative property" refer to in solutions?

Correct answer: b

Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.

3. What cellular process ensures accurate transmission of genetic material during cell division?

Correct answer: A

Rationale: Rationale: A) Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. B) Meiosis is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells). While meiosis also involves the transmission of genetic material, it is specifically geared towards generating genetic diversity through recombination and reduction of chromosome number. C) Replication is the process of copying DNA to produce an identical copy. While replication is essential for cell division, it is not the specific process that ensures accurate transmission of genetic material during cell division. D) Transcription is the process by which genetic information in DNA is copied into RNA. Transcription is important for gene ex

4. Identify the spectator ions in the reaction: 2KCl + Pb(NO3)2 → 2KNO3 + PbCl2.

Correct answer: B

Rationale: Rationale: - In the reaction, potassium ions (K+) and chloride ions (Cl-) are present on both sides of the equation. They are not involved in the formation of the products and remain unchanged. - Lead ions (Pb2+) and nitrate ions (NO3-) are involved in the formation of the products potassium nitrate (KNO3) and lead(II) chloride (PbCl2). - Therefore, the spectator ions in this reaction are K+ and Cl-.

5. Which type of nuclear force is responsible for holding protons and neutrons together in the nucleus of an atom?

Correct answer: C

Rationale: The incredibly powerful, strong nuclear force overcomes the repulsive electrostatic force between protons, binding them together and stabilizing the nucleus.

6. What is the correct way to write "25th anniversary" as a word?

Correct answer: D

Rationale: Ordinals (numbers with "th", "st", "nd", etc.) are generally written as words when used before nouns. Option (d) is correct.
