1. Which condition is characterized by inflammation of the inner lining of the stomach?

Correct answer: D

Rationale: Gastritis is the correct answer as it is characterized by inflammation of the inner lining of the stomach. This inflammation can be caused by various factors such as excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), infections, or autoimmune diseases. Symptoms of gastritis may include abdominal pain, nausea, vomiting, and loss of appetite. Gastroesophageal reflux disease (GERD) is incorrect because it involves the backflow of stomach acid into the esophagus, leading to symptoms like heartburn and regurgitation, not inflammation of the stomach lining. Diverticulitis refers to inflammation or infection of small pouches that can form in the walls of the colon, not the stomach. Ulcerative colitis is a type of inflammatory bowel disease characterized by inflammation and ulcers in the colon and rectum, not the stomach lining.

2. Which term in physics describes the resistance of an object to changes in its motion?

Correct answer: A

Rationale: Inertia is the term that describes the resistance of an object to changes in its motion. This property is explained by Newton's First Law of Motion, which states that objects tend to maintain their state of motion unless acted upon by an external force. Inertia is closely related to mass, where objects with more mass exhibit more resistance to changes in motion. Momentum (B) is the product of an object's mass and velocity, gravity (C) is the force of attraction between objects, and kinetic energy (D) is the energy associated with an object's motion. Therefore, the correct answer is A because inertia specifically addresses the resistance of an object to changes in its motion.

3. What is the primary function of the kidneys?

Correct answer: B

Rationale: The primary function of the kidneys is to filter blood and remove waste products from the body, producing urine in the process. This function helps in maintaining the body's internal environment stable, a process known as homeostasis. Option A, 'To digest food,' is incorrect as digestion primarily occurs in the gastrointestinal system, not in the kidneys. Option C, 'To absorb nutrients,' is also incorrect because nutrient absorption mainly takes place in the intestines. Option D, 'To transport oxygen,' is incorrect as the lungs and circulatory system are responsible for oxygen transport, not the kidneys.

4. What is the main function of lysosomes?

Correct answer: A

Rationale: The main function of lysosomes is to break down and recycle cellular waste materials, such as old organelles, foreign substances, and cellular debris. This process is crucial for maintaining cellular homeostasis and proper functioning. Storing carbohydrates (B), synthesizing lipids (C), and transcribing DNA into mRNA (D) are not functions typically associated with lysosomes. Storing carbohydrates is primarily done by other organelles like vacuoles. Synthesizing lipids is a function usually associated with the endoplasmic reticulum and transcribing DNA into mRNA occurs in the nucleus by the process of transcription.

5. What might happen if blood sugar begins to drop in the human body?

Correct answer: D

Rationale: When blood sugar levels drop in the body, the pancreas releases glucagon. Glucagon acts to increase blood sugar levels by stimulating the liver to release stored glucose into the bloodstream. Therefore, the correct answer is D. Choice A is incorrect because the release of insulin lowers blood sugar levels, opposite of what happens when blood sugar is dropping. Choice B is incorrect as the liver releases stored glucose in response to low blood sugar, not when blood sugar is already dropping. Choice C is also incorrect as the liver stores glucose as glycogen but doesn't directly impact blood sugar levels dropping in the moment.
