Biology

1. What is the main function of peroxisomes in the cell?

Correct answer: A

Rationale: Rationale: Peroxisomes are membrane-bound organelles found in eukaryotic cells that contain enzymes involved in various metabolic processes. One of the main functions of peroxisomes is to break down hydrogen peroxide, a toxic byproduct of metabolism, into water and oxygen through the action of the enzyme catalase. This process helps protect the cell from oxidative damage caused by hydrogen peroxide. While peroxisomes are involved in other metabolic functions such as lipid metabolism and the synthesis of bile acids, their primary role is the breakdown of hydrogen peroxide.

2. What are chromosomes made of?

Correct answer: B

Rationale: Rationale: Chromosomes are structures found in the nucleus of cells that contain genetic material. They are made up of DNA (deoxyribonucleic acid), which carries the genetic information, and proteins that help in the organization and packaging of the DNA. While RNA is involved in various cellular processes, it is not a major component of chromosomes. Carbohydrates are not a significant component of chromosomes. Therefore, the most accurate answer is B) DNA and proteins.

3. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

Correct answer: C

Rationale: Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This description fits plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.

4. The large intestine absorbs water and electrolytes from digested food material. What waste product remains after water absorption and is eventually eliminated from the body?

Correct answer: D

Rationale: The large intestine is responsible for absorbing water and electrolytes from digested food material. As the waste material moves through the large intestine, most of the water is absorbed, leaving behind waste products known as feces. Feces consist of indigestible material, bacteria, and some remaining waste products. This waste is eventually eliminated from the body through the process of defecation. Chyme refers to the semi-fluid mass of partially digested food that moves from the stomach to the small intestine. Bolus is a term used to describe a mass of chewed food ready to be swallowed. Glucose is a simple sugar that is absorbed in the small intestine and used as an energy source. Therefore, the correct answer is D: Feces.

5. Which of the following statements is true regarding a supersaturated solution?

Correct answer: a

Rationale: Supersaturated solutions are unstable and tend to crystallize if disturbed. The other choices do not accurately describe supersaturated solutions.

6. A decorative box has a rectangular base (20cm by 15cm) and a hemispherical top with the same diameter as the base. What is the total surface area of the box (excluding the base)?

Correct answer: C

Rationale: Calculate the surface area of the lateral sides and the hemisphere, then add them up.
