1. What can be inferred about the data collected by smart cities?
- A. It is easily accessible and transparent to the public.
- B. It is solely used for optimizing infrastructure and services.
- C. It may raise privacy concerns for individual citizens.
- D. It is always accurate and free from technical errors.
Correct answer: C
Rationale: The passage specifically mentions concerns about data privacy, implying potential issues for individuals.
2. Pseudostratified columnar epithelium
- A. Skeletal muscle
- B. Bony skeleton
- C. External ears
- D. Bloodstream
Correct answer: C
Rationale: The correct answer is C: External ears. Pseudostratified columnar epithelium is a type of epithelial tissue found in the respiratory tract, where it appears to be stratified but all cells are anchored to the basement membrane. The external ears are lined with pseudostratified columnar epithelium to help protect and support the structures of the ear canal. Skeletal muscle (A) is a type of muscle tissue, bony skeleton (B) refers to bones, and bloodstream (D) is a system for blood circulation, which are not related to pseudostratified columnar epithelium.
3. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?
- A. Gravitational force
- B. Normal force from the ground
- C. Air resistance
- D. The force of throwing
Correct answer: C
Rationale: Gravitational force acts downwards, normal force is perpendicular to motion at the launch point, and the throwing force is gone after release. Only air resistance acts continuously to oppose horizontal motion.
4. Which type of tissue is characterized by tightly packed cells with minimal extracellular matrix and provides structural support and protection?
- A. Epithelial tissue
- B. Connective tissue
- C. Muscle tissue
- D. Nervous tissue
Correct answer: B
Rationale: The correct answer is B: Connective tissue. Connective tissue is characterized by tightly packed cells with minimal extracellular matrix, which provides structural support and protection. Epithelial tissue, while also tightly packed, is specialized for lining and covering surfaces. Muscle tissue is composed of cells with contractile properties for movement, and nervous tissue is made up of neurons for transmitting electrical signals. Therefore, connective tissue best fits the description of being densely packed with cells and serving a structural support and protective function.
5. Which respiratory structure is responsible for vocalization and sound production?
- A. Trachea
- B. Larynx
- C. Bronchi
- D. Alveoli
Correct answer: B
Rationale: The correct answer is B: Larynx. The larynx, also known as the voice box, is the respiratory structure responsible for vocalization and sound production. It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) is the windpipe that carries air to and from the lungs. The bronchi (C) are the main airways that branch off from the trachea into the lungs. The alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not directly involved in vocalization.
6. What are isotopes?
- A. Atoms of the same element with different numbers of protons.
- B. Atoms of the same element with different numbers of neutrons.
- C. Atoms of different elements with the same number of protons.
- D. Atoms of different elements with the same number of electrons.
Correct answer: B
Rationale: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This means that isotopes have the same atomic number (Z) but different mass numbers (A). For example, carbon-12 (¹²C), carbon-13 (¹³C), and carbon-14 (¹â´C) are all isotopes of carbon. They all have six protons in their nuclei, but they have different numbers of neutrons: carbon-12 has six neutrons, carbon-13 has seven neutrons, and carbon-14 has eight neutrons.
