physics
1. What type of energy is stored in food?
- A. Mechanical energy
- B. Kinetic energy
- C. Chemical potential energy
- D. Thermal energy
Correct answer: c
Rationale: Food stores energy in the form of chemical potential energy, which can be released during metabolic processes.
2. Which lobe of the brain is primarily responsible for processing visual information?
- A. Frontal lobe
- B. Parietal lobe
- C. Temporal lobe
- D. Occipital lobe
Correct answer: d
Rationale: The correct answer is D: Occipital lobe. The occipital lobe is located at the back of the brain and is primarily responsible for processing visual information. This area contains the primary visual cortex, which interprets signals from the eyes and processes visual stimuli such as color, shape, and motion. The frontal lobe is more involved in higher-level thinking and decision-making processes, the parietal lobe is responsible for processing sensory information and spatial awareness, and the temporal lobe is involved in memory and auditory processing. Therefore, the occipital lobe is the main region dedicated to visual processing in the brain.
3. What is the Aufbau principle?
- A. The principle that electrons fill orbitals in order of increasing energy.
- B. The principle that electrons cannot be in the same orbital with the same spin.
- C. The principle that the maximum number of electrons in an orbital is 2n^2, where n is the energy level of the orbital.
- D. The principle that the attractive force between an electron and the nucleus is inversely proportional to the distance between them.
Correct answer: A
Rationale: The Aufbau principle is a fundamental concept in atomic structure that determines the order in which electrons fill the available orbitals in an atom. It states that electrons occupy orbitals in order of increasing energy levels, starting with the lowest energy level and progressing to higher energy levels. This principle is based on the fact that electrons in lower energy levels are more stable and have a lower energy state than electrons in higher energy levels.
4. Which vitamin deficiency can lead to kidney stones?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin D
- D. Vitamin K
Correct answer: D
Rationale: The correct answer is D, Vitamin K. Vitamin K plays a role in blood clotting and bone health. A deficiency in Vitamin K can lead to an increased risk of kidney stones due to the improper regulation of calcium in the body. Calcium can accumulate in the kidneys and form stones if not properly managed. Vitamin K deficiency can disrupt the balance of calcium in the body, contributing to the development of kidney stones. Therefore, it is important to ensure an adequate intake of Vitamin K to prevent kidney stone formation.
5. A reaction between an acid and a base is known as:
- A. Precipitation
- B. Neutralization
- C. Oxidation-reduction
- D. Photolysis
Correct answer: B
Rationale: When an acid and a base react, they neutralize each other's properties
6. The least common multiple (LCM) of two numbers is the smallest number that is a multiple of both. Which of the following represents the LCM of 14 and 21?
- A. 42
- B. 63
- C. 84
- D. 168
Correct answer: C
Rationale: We can list out the multiples of each number until we find a common multiple. 14, 28, 42, 56, 84, ... 21, 42, 63, 84, ... The least common multiple is 84.
