2. Which statement correctly describes the concept of ionization energy?

Correct answer: A

Rationale: The energy required to remove an electron from an outermost shell. Ionization energy varies depending on the element and electron configuration, indicating its difficulty to lose electrons and influencing its reactivity.

3. What is the relationship between the frequency and wavelength of a wave?

Correct answer: a

Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.

4. What is the function of ribosomes?

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.

5. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

Correct answer: d

Rationale: Constructive interference happens when identical waves meet in phase, resulting in a wave with increased amplitude.

6. hich word is most closely associated with the adjective "meticulous"?

Correct answer: B
