1. What cellular process ensures accurate transmission of genetic material during cell division?
- A. Mitosis (somatic cell division)
- B. Meiosis (germ cell division)
- C. Replication (DNA duplication)
- D. Transcription (DNA to RNA conversion)
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
2. Which type of cell has a nucleus but lacks membrane-bound organelles?
- A. Plant cell
- B. Prokaryotic cell
- C. Animal cell
- D. Fungal cell
Correct answer: B
Rationale: The correct answer is B: Prokaryotic cell. Prokaryotic cells are characterized by having a nucleus, known as the nucleoid, which contains genetic material but lacks a membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Plant and animal cells (options A and C) are eukaryotic cells that have a nucleus and membrane-bound organelles. Fungal cells (option D) are also eukaryotic cells with a nucleus and organelles. Understanding the difference between prokaryotic and eukaryotic cells is essential in biology to grasp the diversity of cell structure and function.
3. Which of the following describes a vector quantity?
- A. Speed
- B. Distance
- C. Mass
- D. Velocity
Correct answer: d
Rationale: Velocity is a vector quantity as it includes both magnitude (speed) and direction.
4. In a neutral atom, the number of electrons:
- A. Must be equal to the number of protons.
- B. Must be less than the number of protons.
- C. Must be greater than the number of neutrons.
- D. Can vary depending on the atom's temperature.
Correct answer: A
Rationale: Must be equal to the number of protons - For electrical neutrality, the positive charge of protons must be balanced by the negative charge of an equal number of electrons.
5. What is the author's stance towards the idea of smart cities?
- A. Strongly supportive, emphasizing only the benefits.
- B. Strongly critical, focusing solely on the drawbacks.
- C. Balanced and objective, highlighting both potential and concerns.
- D. Indecisive and unclear about the overall value of smart cities.
Correct answer: C
Rationale: The passage acknowledges both the promise and challenges of smart cities, demonstrating a balanced perspective.
6. In a horizontal chart, the lowest level worker is located at the
- A. Leftmost box
- B. Middle
- C. Rightmost box
- D. Bottom
Correct answer: B
Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.
