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. What is the process of converting ammonia, a byproduct of protein digestion, into a less toxic form?

• A. Deamination
• B. Transamination
• C. Decarboxylation
• D. Hydrolysis

Correct answer: A

Rationale: Rationale: Deamination is the process of removing an amino group from a molecule, such as converting ammonia (NH3) into a less toxic form like urea. Ammonia is a byproduct of protein digestion and needs to be converted into a less toxic form to be excreted from the body. Deamination is a key step in this process, which occurs mainly in the liver through the urea cycle. Transamination involves the transfer of an amino group from one molecule to another, not the removal of an amino group as in deamination. Decarboxylation is the removal of a carboxyl group from a molecule, and hydrolysis is the breakdown of a compound by adding water.

3. The K-capture process, a type of electron capture, involves the capture of an electron from which electron shell:

• A. The outermost s-orbital
• B. An inner p-orbital
• C. An inner d-orbital
• D. Any available electron shell

Correct answer: A

Rationale: The K-capture process involves the capture of an electron from the innermost electron shell, known as the K-shell. The K-shell is represented by the outermost s-orbital in an atom's electron configuration. When an electron from the K-shell is captured, it results in the transition of a proton to a neutron in the nucleus, thereby changing the atomic number of the element. Therefore, option A, 'The outermost s-orbital,' is the correct answer as it accurately describes the electron shell involved in the K-capture process.

4. What defines the period of a wave?

• A. The number of waves passing a point per unit time
• B. The distance between two adjacent crests or troughs
• C. The time it takes for one complete wave cycle to pass a point
• D. The maximum displacement of particles in a medium due to the wave

Correct answer: C

Rationale: The period of a wave is defined as the time it takes for one complete wave cycle to pass a point. It is typically measured in seconds and is inversely related to the frequency of the wave. The period is not related to the number of waves passing a point per unit time (A), the distance between two adjacent crests or troughs (B), or the maximum displacement of particles in a medium due to the wave (D).

5. What happens to the work done on an object when the angle between force and displacement is 90 degrees?

• A. Maximum work is done
• B. No work is done
• C. Minimum work is done
• D. Work is infinite

Correct answer: b

Rationale: When the angle between force and displacement is 90 degrees, the work done on the object is zero.

6. The lymphatic system is primarily responsible for:

• A. Transporting nutrients throughout the body
• B. Removing excess fluids and waste products from tissues
• C. Producing red blood cells
• D. Regulating body temperature

Correct answer: B

Rationale: The correct answer is B: 'Removing excess fluids and waste products from tissues.' The lymphatic system plays a crucial role in maintaining fluid balance in the body by collecting excess interstitial fluid and returning it to the bloodstream. This system also helps in removing waste products, pathogens, and toxins from tissues, contributing to the body's immune response. Options A, C, and D are incorrect because transporting nutrients, producing red blood cells, and regulating body temperature are primarily the functions of other systems in the body such as the circulatory system, bone marrow, and the thermoregulatory system, respectively.
