1. 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

2. The longest bone in the human body is the:

• A. Tibia
• B. Fibula
• C. Femur
• D. Humerus

Correct answer: C

Rationale: The correct answer is C: "Femur." The femur is the longest bone in the human body, located in the thigh region and connecting the hip to the knee. It plays a crucial role in supporting the body's weight and facilitating movement. The tibia and fibula are bones in the lower leg, while the humerus is a bone in the upper arm. Therefore, the femur is the correct answer for the longest bone in the human body.

3. A pressure vessel has a cylindrical body (diameter 10cm, height 20cm) with hemispherical ends (same diameter as the cylinder). What is its total surface area?

• A. 785 sq cm
• B. 1130 sq cm
• C. 1570 sq cm
• D. 2055 sq cm

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and two hemispheres. Add them all up for the total surface area.

4. What is the name of the regulatory region in a gene that controls its expression?

• A. Exon
• B. Intron
• C. Promoter
• D. Enhancer

Correct answer: C

Rationale: Rationale: A) Exon: Exons are the coding regions of a gene that are transcribed into mRNA and eventually translated into proteins. Exons do not regulate gene expression. B) Intron: Introns are non-coding regions of a gene that are removed during RNA processing and do not play a direct role in controlling gene expression. C) Promoter: The promoter is a regulatory region located at the beginning of a gene that initiates the process of transcription by binding transcription factors and RNA polymerase. It plays a crucial role in controlling gene expression. D) Enhancer: Enhancers are regulatory regions that can be located far from the gene they regulate and can increase the transcription of a gene. While enhancers are important for gene expression, the specific region that controls gene expression is the promoter. Therefore, the correct answer is C) Promoter, as it is the regulatory region in a gene that controls its expression by initiating transcription.

5. Where does fertilization, the fusion of sperm and egg, typically occur in the human body?

• A. Ovary
• B. Uterus
• C. Fallopian tube
• D. Vagina

Correct answer: C

Rationale: The correct answer is C: Fallopian tube. Fertilization, the fusion of sperm and egg, typically occurs in the fallopian tube. After ovulation, the egg is released from the ovary and travels through the fallopian tube where it may encounter sperm for fertilization. The fertilized egg then moves to the uterus for implantation and development. The ovary releases the egg but fertilization occurs in the fallopian tube, making it the correct answer.

6. What is the general formula for an alcohol?

• A. CnH2n
• B. CnH2n+2
• C. CnH2n-1
• D. CnH2nO

Correct answer: D

Rationale: The general formula for an alcohol is \(C_nH_{2n}O\), indicating the presence of a hydroxyl group (-OH).
