1. What is the function of ribosomes?

• A. Packaging and transporting proteins
• B. Storing genetic material
• C. Controlling cell division
• D. Synthesizing proteins

Correct answer: D

Rationale: The correct answer is D: 'Synthesizing proteins.' Ribosomes are the cellular organelles responsible for protein synthesis. They read the mRNA and assemble amino acids into proteins according to the genetic information encoded in the mRNA. This process is crucial for building and maintaining cellular structures, enzymes, and various other proteins essential for the functioning of the cell. Options A, B, and C do not accurately describe the primary function of ribosomes, making them incorrect choices for this question.

2. What is the name of the monthly cycle in females that prepares the body for potential pregnancy?

• A. Ovulation cycle
• B. Menstrual cycle
• C. Implantation cycle
• D. Gestation cycle

Correct answer: B

Rationale: The correct answer is B: Menstrual cycle. The menstrual cycle is the monthly process in females where the lining of the uterus thickens in preparation for a potential pregnancy. If pregnancy does not occur, the lining sheds, resulting in menstruation. Ovulation is a key event within the menstrual cycle where an egg is released from the ovary, typically around the midpoint of the cycle. Implantation refers to the attachment of a fertilized egg to the uterus, which occurs after ovulation and fertilization. Gestation cycle refers to the period of pregnancy from conception to birth. Therefore, the menstrual cycle best describes the monthly process that prepares the body for potential pregnancy.

3. The final sentence suggests that users should approach social media with a healthy dose of

• A. Enthusiasm and optimism about its potential for connection and engagement.
• B. Skepticism and critical thinking towards the information encountered online.
• C. Acceptance of its flaws and a passive reliance on its features for interaction.
• D. Indifference towards its impacts and an absence of any effort to manage its use.

Correct answer: B

Rationale: The emphasis on "critical thinking" and "skepticism" suggests the importance of approaching social media with a cautious and discerning mind, aligning with B

4. What property of matter determines its resistance to changes in shape or size?

• A. Solid
• B. Liquid
• C. Gas
• D. Plasma

Correct answer: B

Rationale: Liquids have a definite volume but can take the shape of their container, unlike solids with fixed shapes and volumes.

5. What is the term for the process of converting a liquid into a gas at a temperature below its boiling point?

• A. Vaporization
• B. Evaporation
• C. Condensation
• D. Sublimation

Correct answer: B

Rationale: Evaporation is the process of converting a liquid into a gas at a temperature below its boiling point. The other choices describe different phase changes.

6. In a neutral atom, the number of electrons:

• A. Must be equal to the number of protons.
• B. Must be less than the number of protons.
• C. Must be greater than the number of neutrons.
• D. Can vary depending on the atom's temperature.

Correct answer: A

Rationale: Must be equal to the number of protons - For electrical neutrality, the positive charge of protons must be balanced by the negative charge of an equal number of electrons.
