✍️ Sample MISA Questions & Answers
1. The world's oceans absorb a significant amount of the carbon dioxide released into the atmosphere by human activities. Which of the following is a direct chemical consequence of this absorption?
When excess carbon dioxide (CO₂) dissolves in seawater, it forms carbonic acid (H₂CO₃), which lowers the ocean's pH. This process, known as ocean acidification, reduces the availability of carbonate ions that marine organisms like corals, clams, and oysters need to build their shells and skeletons.
2. Solve for x in the equation 2x + 5 = 13.
Explanation: To solve the equation 2x + 5 = 13: Subtract 5 from both sides: 2x = 13 − 5 2x = 8 Now, divide both sides by 2 to solve for x: x = 8/2 x = 4
3. What is the next number in the sequence: 2, 5, 8, 11, ...?
Explanation: To find the next number in the sequence, we observe that each number is increasing by 3: 2, 5, 8, 11,... So, to find the next number, we add 3 to the last number in the sequence: 11 + 3 = 14
4. A student is examining a diagram of genetic material. Which of the following statements correctly describes the relationship between DNA, genes, and chromosomes?
The correct answer accurately represents the hierarchical structure of genetic material. Chromosomes, located in the nucleus of eukaryotic cells, are tightly coiled structures composed of DNA and proteins. A gene is a specific sequence or segment of this DNA that holds the instructions for building a specific protein or functional RNA molecule, which in turn determines a particular trait.
5. According to the most widely accepted scientific theory, how did the planets in our solar system form?
The nebular hypothesis is the most accepted model for the formation of the solar system. It states that a giant cloud of gas and dust (a nebula) collapsed under gravity, forming a spinning protoplanetary disk. The Sun formed at the center, and the planets were created through the process of accretion, where dust and gas particles stuck together and gradually grew larger.
6. How do radio waves and visible light differ?
Radio waves have wavelengths ranging from millimeters to kilometers and much lower frequencies than visible light, placing them at the opposite end of the electromagnetic spectrum.
