Question 1 of 5

What is cystitis an inflammation of?

Correct Answer: B

Rationale: Cystitis is an inflammation of the bladder. It is typically caused by a bacterial infection and can lead to symptoms such as frequent urination, pain or burning during urination, and lower abdominal discomfort. The inflammation specifically affects the bladder lining. Choices A, C, and D are incorrect. Kidneys are not the site of inflammation in cystitis; they are associated with conditions like pyelonephritis. Ureters are tubes that connect the kidneys to the bladder, and the urethra is the tube that carries urine from the bladder to outside the body. Therefore, the correct answer is 'Bladder.'

Question 2 of 5

What is the difference between a phylum and a class?

Correct Answer: A

Rationale: In biological classification, a phylum is a higher taxonomic rank than a class. A phylum is a broader category that encompasses multiple classes within it. It represents a group of organisms sharing a common body plan or evolutionary history. On the other hand, a class is a more specific category within a phylum that includes organisms with similar characteristics. Therefore, phyla are broader and more general compared to classes. Choice B is incorrect because classes are more specific categories within phyla. Choice C is incorrect as phyla and classes are distinct hierarchical levels in taxonomy. Choice D is incorrect because phyla and classes are not restricted to specific types of organisms; they can apply to various organisms across the biological kingdom.

Question 3 of 5

What is the energy required to break a chemical bond called?

Correct Answer: C

Rationale: Activation energy is the energy required to break a chemical bond and initiate a chemical reaction. It is the minimum amount of energy needed to start a chemical reaction by breaking bonds in the reactant molecules. Kinetic energy (option A) is the energy of motion and is not directly related to breaking chemical bonds. Potential energy (option B) is stored energy that can be converted into other forms of energy but is not specifically about breaking chemical bonds. Bond energy (option D) refers to the energy required to break a particular chemical bond in a molecule and is not the general term for the energy needed to break any chemical bond. Activation energy is crucial in determining the rate of a chemical reaction as it affects the probability of reactant molecules colliding with sufficient energy to surpass the energy barrier and form products.

Question 4 of 5

Which of the following is a MAJOR consequence of a stroke?

Correct Answer: C

Rationale: A major consequence of a stroke is brain damage due to interrupted blood flow. Strokes occur when blood flow to the brain is blocked or reduced, leading to the death of brain cells. This interruption in blood flow results in brain damage, which can cause physical and cognitive impairments such as paralysis, speech difficulties, memory problems, and sensory disturbances. The severity and location of the stroke determine the extent of the consequences experienced by the individual. Choices A, B, and D are incorrect. Irregular heart rhythm is not a direct consequence of a stroke but may occur as a complication. Rapid weight gain or loss and chronic fatigue with muscle weakness are not typically considered major consequences of a stroke, which primarily affects the brain due to interrupted blood flow.

Question 5 of 5

Identify the INCORRECT function of the liver.

Correct Answer: D

Rationale: A) Correct - The liver produces bile, which aids in the digestion and absorption of fats in the small intestine. B) Correct - The liver is responsible for synthesizing blood proteins, including albumin, which helps maintain osmotic pressure in the blood. C) Correct - The liver stores glucose in the form of glycogen and helps regulate blood sugar levels by releasing glucose when needed. D) Incorrect - The liver does not filter waste products from the blood. Instead, the kidneys are responsible for filtering waste products from the blood and excreting them in the form of urine.
