1. In which group of the periodic table are alkali metals located?

Correct answer: A

Rationale: Alkali metals, such as lithium, sodium, and potassium, are located in Group 1 of the periodic table. This group is known for its highly reactive properties, low melting points, and the tendency to form alkaline solutions when they react with water. Group 2 consists of alkaline earth metals and not alkali metals, making choice B incorrect. Group 7 includes halogens, while Group 8 includes noble gases. These groups do not contain alkali metals, so choices C and D are also incorrect. Therefore, the correct answer is Group 1.

2. Which of the following structures in the cell is responsible for producing ATP?

Correct answer: C

Rationale: The correct answer is C, Mitochondria. Mitochondria are known as the powerhouse of the cell and are responsible for producing ATP, the primary energy currency of the cell through cellular respiration. Ribosomes (Choice A) are involved in protein synthesis, the nucleus (Choice B) stores genetic material and controls cell activities, and the endoplasmic reticulum (Choice D) plays a role in protein synthesis, lipid metabolism, and detoxification, but none of these structures are directly responsible for producing ATP.

3. The control center of the cell, containing genetic information (DNA), is the:

Correct answer: C

Rationale: The correct answer is C, the nucleus. The nucleus is the control center of the cell and houses the genetic information in the form of DNA. The Golgi apparatus (choice A) is responsible for packaging and processing proteins, the ribosome (choice B) is involved in protein synthesis, and the endoplasmic reticulum (choice D) is involved in protein and lipid synthesis. Therefore, choices A, B, and D are not the correct answers as they do not house the genetic information or serve as the control center of the cell.

4. Which of the following statements is true about an allergic reaction?

Correct answer: C

Rationale: The correct answer is C. Mast cells are responsible for releasing histamine and other chemicals during an allergic response. Choice A is incorrect because hives and wheezing are symptoms of an allergic reaction, not the causes. Choice B is incorrect as B-cells are not directly involved in allergic reactions. Choice D is incorrect as keratin and collagen are not typically involved in allergic reactions, and histamine is released by mast cells.

5. Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?

Correct answer: D

Rationale: Volume is the property of matter that refers to the amount of space occupied by an object. It is measured in cubic units, such as cubic meters or cubic centimeters. Mass, on the other hand, is the amount of matter in an object, weight is the force of gravity acting on an object, and density is the mass per unit volume of a substance. In this question, the key concept is the space occupied by an object, which directly relates to volume, making it the correct answer. Choices A, B, and C are incorrect as they do not specifically pertain to the amount of space occupied by an object.
