Physics

1. Entropy (S) is a thermodynamic property related to the system's disorder. According to the second law of thermodynamics, in a spontaneous process:

Correct answer: A

Rationale: Entropy is a measure of a system's disorder or randomness. According to the second law of thermodynamics, in a spontaneous process, the total entropy of the system and surroundings increases, leading to a higher level of disorder or randomness. This increase in total entropy is consistent with the idea that systems tend towards higher entropy states over time. Therefore, option A is correct because it aligns with the principle that the total entropy of a closed system, including both the system and its surroundings, will increase in a spontaneous process.

2. Which property of a substance refers to its ability to undergo a chemical change and form new substances?

Correct answer: c

Rationale: Reactivity refers to a substance's ability to undergo chemical changes, forming new substances with different properties.

3. A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?

Correct answer: C

Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 6 * 8mm = 48mm.

4. What is the periodic table?

Correct answer: B

Rationale: The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties. Elements are arranged in rows (periods) and columns (groups) with similar properties. The elements are listed in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement reveals a periodic repetition of chemical properties, which is the basis of the periodic law.

5. Which of the following organelles is responsible for the production of proteins in the cell?

Correct answer: A

Rationale: The correct answer is A: Ribosomes. Ribosomes are the organelles responsible for protein synthesis in the cell. They are found in both prokaryotic and eukaryotic cells and can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the messenger RNA (mRNA) and translate the genetic code into proteins through a process called translation. The Golgi apparatus is involved in processing and packaging proteins for secretion, while mitochondria are responsible for energy production. Lysosomes are involved in digestion and waste removal within the cell.

6. Which of the following describes the difference between prokaryotic and eukaryotic cells?

Correct answer: A

Rationale: The correct answer is A: 'Prokaryotic cells have a nucleus, while eukaryotic cells don't.' Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles, while eukaryotic cells have a true nucleus enclosed within a nuclear membrane. This distinction is a fundamental difference between the two cell types. Choice B is incorrect because eukaryotic cells are actually more complex than prokaryotic cells due to their membrane-bound organelles. Choice C is incorrect because prokaryotic cells lack membrane-bound organelles. Choice D is incorrect because eukaryotic cells have both a true nucleus and membrane-bound organelles, unlike prokaryotic cells. Understanding this key difference is crucial in understanding the diversity of cell types in living organisms.
