1. What is the primary function of the ovaries in the female reproductive system?

Correct answer: C

Rationale: The primary function of the ovaries in the female reproductive system is to produce eggs (ova). Ovaries are responsible for the production of female gametes. Additionally, they secrete hormones such as estrogen and progesterone, which are essential for the menstrual cycle and pregnancy. Transporting sperm to the uterus is the function of the fallopian tubes, not the ovaries. Producing milk for feeding offspring is the role of the mammary glands, not the ovaries. Regulating urination is a function associated with the urinary system, not the female reproductive system or the ovaries.

2. What is the process by which RNA molecules are modified after transcription but before translation?

Correct answer: B

Rationale: B) Splicing is the correct answer. Splicing is the process by which non-coding regions (introns) are removed from pre-mRNA, and the remaining coding regions (exons) are joined together to form mature mRNA. This modification occurs after transcription but before translation. A) Replication is incorrect as replication is the process by which DNA is copied to produce a new DNA molecule, not RNA modifications. C) Editing may involve RNA editing, but it is not commonly used to describe the modification of RNA molecules after transcription. D) Packaging is not the correct term as it refers to the condensation and organization of DNA into chromatin in eukaryotic cells, not the modification of RNA molecules.

3. Which muscle is the largest in the human body?

Correct answer: A

Rationale: The correct answer is A, the gluteus maximus (buttocks). The gluteus maximus is indeed the largest muscle in the human body, located at the back of the hip and stretching from the sacrum to the femur. This muscle is crucial for hip joint extension, playing a significant role in various activities such as walking, running, and climbing stairs. Choices B, C, and D are incorrect. While the quadriceps femoris, erector spinae, and pectoralis major are also important muscles, they are not the largest muscle in the human body.

4. Where is the major site for nutrient absorption in the digestive system?

Correct answer: C

Rationale: The small intestine is recognized as the major site for nutrient absorption in the digestive system. It plays a crucial role in the digestion and absorption of nutrients from food. The small intestine's villi and microvilli provide a large surface area specialized for absorbing nutrients like carbohydrates, proteins, fats, vitamins, and minerals. This efficient absorption process is essential for supplying the body with the necessary nutrients for energy production, growth, and overall functioning. The mouth is primarily involved in the initial stages of digestion through mechanical and chemical breakdown of food. The stomach aids in further mechanical and chemical digestion but is not the primary site for nutrient absorption. The large intestine's main function is to absorb water and electrolytes, not nutrients.

5. Which method is most suitable for measuring the volume of a cube?

Correct answer: B

Rationale: The correct answer is B. To measure the volume of a cube, you need to use a mathematical formula that takes into account the dimensions of the cube, specifically the length of its sides. Using a measuring wheel alone or a triple beam balance is not suitable for determining the volume of a cube. A graduated cylinder is used to measure the volume of liquids, not geometric solids like cubes.
