1. What is the function of the urinary bladder?

• A. To filter waste from the blood
• B. To store urine
• C. To regulate fluid balance
• D. To remove waste from the body

Correct answer: B

Rationale: The correct answer is B: To store urine. The urinary bladder's primary function is to store urine produced by the kidneys until it is ready to be excreted from the body. It acts as a reservoir that temporarily holds urine until an appropriate time for elimination. Choices A, C, and D are incorrect because the urinary bladder does not filter waste from the blood, regulate fluid balance, or directly remove waste from the body. These functions are primarily carried out by the kidneys and other organs in the excretory system.

2. How many electron pairs are shared to form a double covalent bond?

• A. 1
• B. 2
• C. 3
• D. 4

Correct answer: B

Rationale: The correct answer is B. In a double covalent bond, two pairs of electrons are shared between two atoms. This sharing of two electron pairs results in a stronger bond compared to a single covalent bond where only one pair of electrons is shared. Choice A is incorrect because a single covalent bond involves the sharing of one pair of electrons. Choices C and D are incorrect as they do not represent the correct number of electron pairs shared in a double covalent bond.

3. Choose the meaning of the word rationale in the following sentence: "Step-by-step, the doctor explained the rationale for the treatment."

• A. Reasoning
• B. Prescription
• C. Procedure
• D. Necessity

Correct answer: A

Rationale: Corrected Question: In this context, the word 'rationale' refers to the underlying reasoning or justification for the treatment being explained step-by-step by the doctor. It pertains to the logical basis or thought process behind the chosen course of action. 'Prescription' (Choice B), 'Procedure' (Choice C), and 'Necessity' (Choice D) do not accurately capture the meaning of 'rationale' in the sentence provided.

4. A patient weighs 180 pounds. What is their weight in kilograms (1kg = 2.2lbs)?

• A. 68kg
• B. 75kg
• C. 82kg
• D. 90kg

Correct answer: C

Rationale: To convert pounds to kilograms, you need to divide the weight in pounds by the conversion factor of 2.2 (1kg = 2.2lbs). 180 pounds / 2.2 = 81.82 kg Rounded to the nearest whole number, the weight of 180 pounds is approximately 82kg. Therefore, the correct answer is 82kg, which is option C. Option B (75kg) is not correct as it is significantly lower than the calculated value. Options A (68kg) and D (90kg) are also incorrect as they do not match the converted weight of 180 pounds.

5. Ocean waves may tear sponges into pieces, each of which may grow into a new sponge. What is this form of reproduction called?

• A. Budding
• B. Vegetative propagation
• C. Binary fission
• D. Fragmentation

Correct answer: D

Rationale: Fragmentation is the form of asexual reproduction where an organism breaks into fragments, and each fragment can grow into a new individual. In the case of sponges being torn into pieces by ocean waves, each piece has the potential to develop into a new sponge, making fragmentation the correct answer in this scenario. Budding is a form of asexual reproduction where a new organism develops as an outgrowth from the parent organism. Vegetative propagation involves the growth of new individuals from plant parts like stems or roots. Binary fission is a method of reproduction seen in some single-celled organisms where one cell divides into two identical cells.
