Biology
1. What is the process of converting simple sugars into complex carbohydrates called?
- A. Glycolysis
- B. Gluconeogenesis
- C. Krebs cycle
- D. Oxidative phosphorylation
Correct answer: B
Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate to produce energy. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids or glycerol. C) The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that generate energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. D) Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced using energy derived from the electron transport chain.
2. What is the term for a solution that contains less solute than the maximum amount it could dissolve at a specific temperature and pressure?
- A. Saturated solution
- B. Unsaturated solution
- C. Supersaturated solution
- D. Concentrated solution
Correct answer: b
Rationale: An unsaturated solution is one in which less solute has dissolved than the maximum amount it could dissolve under specific conditions. The other choices do not accurately describe an unsaturated solution.
3. What is the waste product of protein digestion?
- A. Glucose
- B. Amino acids
- C. Fatty acids
- D. Ammonia
Correct answer: D
Rationale: Rationale: Protein digestion involves breaking down proteins into their constituent amino acids. During this process, the waste product produced is ammonia. Ammonia is a toxic compound that needs to be converted into urea in the liver and then excreted by the kidneys in the form of urine. Glucose is a product of carbohydrate digestion, amino acids are the building blocks of proteins, and fatty acids are the end products of fat digestion.
4. Which gland in the endocrine system is responsible for the production of red blood cells?
- A. Pituitary gland
- B. Thyroid gland
- C. Thymus gland
- D. Parathyroid gland
Correct answer: C
Rationale: The correct answer is the Thymus gland (option C). The Thymus gland is responsible for the production and maturation of T-lymphocytes, a type of white blood cell involved in immune responses. Red blood cells are not produced by any endocrine gland; instead, they are produced in the bone marrow. The Pituitary gland (option A) secretes hormones that control various body functions, the Thyroid gland (option B) regulates metabolism, and the Parathyroid gland (option D) regulates calcium levels in the blood. Therefore, the Thymus gland is not responsible for the production of red blood cells, making it the correct answer in this case.
5. The largest lymphatic vessel in the body is responsible for draining lymph from most of the body. What is it called?
- A. Jugular vein
- B. Thoracic duct
- C. Subclavian vein
- D. Aorta
Correct answer: B
Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body and is responsible for draining lymph from most of the body. It collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities. The jugular vein (A) is a major blood vessel that drains blood from the head. The subclavian vein (C) is responsible for draining blood from the upper extremities. The aorta (D) is the main artery that carries oxygenated blood away from the heart. Therefore, the thoracic duct is the correct answer for the largest lymphatic vessel in the body.
6. Which element shares the same group (family) on the periodic table with helium (He)?
- A. Neon (Ne)
- B. Boron (B)
- C. Carbon (C)
- D. Oxygen (O)
Correct answer: A
Rationale: Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.
