Correct Answer: D

Rationale: In osmosis, solvent moves from an area of low solute concentration to high solute concentration to equalize concentration. This is due to the principle of diffusion where molecules move from high to low concentration. Choice D is correct as it aligns with this principle. Choice A is incorrect because osmosis involves solvent movement, not solute movement. Choices B and C are incorrect as temperature does not determine the direction of solvent movement in osmosis.

Correct Answer: D

Rationale: The correct answer is D: tRNA. Transfer RNA (tRNA) carries amino acids to ribosomes during protein synthesis. tRNA has an anticodon that pairs with the mRNA codon, ensuring the correct amino acid is added to the growing polypeptide chain. A: DNA carries genetic information but does not directly participate in protein synthesis. B: mRNA carries the genetic information from DNA to the ribosomes but does not carry amino acids. C: rRNA is a structural component of ribosomes and helps in protein synthesis but does not carry amino acids to the ribosomes.

Correct Answer: A

Rationale: The correct answer is A: Solid. Solids have both a definite volume and a definite shape because the particles are tightly packed and vibrate in fixed positions. This leads to a rigid structure and minimal movement, maintaining the shape and volume. In contrast, liquids (B) have a definite volume but take the shape of their container, gases (C) have neither a definite shape nor volume as they expand to fill the container, and plasmas (D) have no definite shape or volume due to their high energy state.

Correct Answer: B

Rationale: The correct answer is B (25 grams) as the recommended daily fiber intake for adults by the American Heart Association is 25-30 grams. Fiber helps with digestion, heart health, and weight management. Option A (10 grams) is too low and insufficient for daily needs. Option C (35 grams) and D (50 grams) are excessive and may lead to digestive issues like bloating or gas. Therefore, B is the most appropriate choice for optimal health benefits.
