Biology

1. What is the function of introns in eukaryotic genes?

Correct answer: C

Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.

2. Which element is present in household bleach and has disinfectant properties?

Correct answer: B

Rationale: Chlorine's oxidizing ability makes it effective in killing bacteria and other microorganisms.

3. The author's tone towards UBI can be described as

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

4. A bottle of hand sanitizer contains 70% alcohol. If 5ml of sanitizer are used, how much pure alcohol is present?

Correct answer: D

Rationale: Multiply the total sanitizer volume (5ml) by the alcohol percentage (70%) to get 3.5ml of pure alcohol.

5. What defines the period of a 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).

6. Which type of fiber is insoluble and promotes gut motility?

Correct answer: B

Rationale: Rationale: A) Pectin is a soluble fiber found in fruits and vegetables. It forms a gel-like substance in the gut and can help lower cholesterol levels. B) Cellulose is an insoluble fiber found in plants, particularly in the cell walls of fruits, vegetables, and whole grains. It adds bulk to the stool and promotes gut motility by aiding in the movement of food through the digestive system. C) Beta-glucan is a soluble fiber found in oats and barley. It can help lower cholesterol levels and improve blood sugar control. D) Guar gum is a soluble fiber derived from guar beans. It can help with digestion and may have a role in managing blood sugar levels. In this case, the question specifically asks for the type of fiber that is insoluble and promotes gut motility, which is characteristic of cellulose.
