1. Which condition is commonly associated with frequent, painful urination?

• A. Diabetes
• B. Urinary tract infection (UTI)
• C. Kidney stones
• D. All of the above

Correct answer: D

Rationale: Frequent, painful urination can be indicative of various conditions. Diabetes may cause increased urination due to high blood sugar levels, UTIs can lead to pain and frequent urination, and kidney stones can also result in painful urination. Therefore, all of the options (A, B, and C) are correct in this scenario, making option D, 'All of the above,' the correct answer. Option D encompasses all the conditions commonly associated with frequent, painful urination, making it the most comprehensive and accurate choice.

2. Which term describes the allele for green eyes?

• A. Dominant
• B. Recessive
• C. Homozygous
• D. Heterozygous

Correct answer: B

Rationale: The correct answer is 'B: Recessive.' In genetics, eye color is determined by multiple genes, with green eyes often being associated with a recessive allele. When an individual carries two copies of the recessive allele for green eyes, they will express this eye color. Dominant alleles are expressed over recessive alleles. Homozygous refers to having two identical alleles for a particular gene, and heterozygous refers to having two different alleles. In this context, the allele for green eyes is recessive, meaning it is expressed only when an individual carries two copies of this specific allele. Therefore, 'Recessive' is the most appropriate term to describe the allele for green eyes, making it the correct answer.

3. Which of the following is responsible for carrying oxygenated blood from the heart to the body?

• A. Vein
• B. Artery
• C. Capillary
• D. Lymphatic vessel

Correct answer: B

Rationale: The correct answer is B: Artery. Arteries carry oxygenated blood away from the heart to the body. Veins carry deoxygenated blood back to the heart, capillaries are tiny blood vessels where gas exchange occurs, and lymphatic vessels are part of the lymphatic system, which is responsible for draining excess fluid from tissues and transporting white blood cells.

4. Which of the following is the largest organ in the human body?

• A. Liver
• B. Brain
• C. Heart
• D. Skin

Correct answer: D

Rationale: The skin is the largest organ in the human body. It covers the entire body, serving as a protective barrier against pathogens, UV radiation, and physical damage. Additionally, the skin plays a crucial role in regulating body temperature and synthesizing vitamin D when exposed to sunlight. Choices A, B, and C are incorrect. The liver is the largest internal organ, the brain is the control center of the body, and the heart is a vital organ responsible for pumping blood throughout the body. However, none of these organs are the largest in terms of surface area or overall size.

5. How are mass and inertia related?

• A. Mass is a measure of inertia
• B. Mass has no relationship with inertia
• C. Inertia is a measure of weight
• D. Inertia increases with decreasing mass

Correct answer: A

Rationale: Mass is a measure of inertia. Inertia is the resistance of an object to changes in its state of motion, and mass quantifies this resistance. Objects with more mass have greater inertia, meaning they are more resistant to changes in their motion. Therefore, mass and inertia are directly related, with mass being a fundamental factor that determines the level of inertia an object possesses. Choice B is incorrect because mass and inertia are indeed related. Choice C is incorrect as inertia is not a measure of weight but rather a property related to an object's mass. Choice D is incorrect because inertia actually increases with increasing mass, not decreasing mass.
