• A. 25 sq cm
• B. 50 sq cm
• C. 125 sq
• D. 150 sq cm

Correct answer: D

Rationale: Use the formula for surface area of a cube: 6 * (side length)^2 = 6 * (5cm)^2 = 125 sq cm.

2. Identify the type of clause in the sentence: "While the rain poured, they huddled inside for warmth."

• A. Main clause
• B. Subordinate clause

3. he adrenal cortex produces a group of steroid hormones called corticosteroids. What is a MAJOR function of corticosteroids?

• A. Regulate insulin sensitivity and blood sugar levels
• B. Control blood pressure and electrolyte balance
• C. Stimulate the immune system and inflammatory response
• D. Promote growth and development during puberty

Correct answer: B

Rationale: The correct answer is B: 'Control blood pressure and electrolyte balance.' Corticosteroids, produced by the adrenal cortex, play a major role in regulating blood pressure and electrolyte balance in the body. These hormones, such as aldosterone, act on the kidneys to control the reabsorption of sodium and water, which in turn affects blood pressure and electrolyte levels. While corticosteroids can have effects on other physiological processes, their primary function is to regulate blood pressure and electrolyte balance, making option B the most appropriate choice in this context.

4. What tool helps scientists identify and classify organisms based on their shared characteristics?

• A. Binomial nomenclature
• B. Cladistics
• C. Dichotomous key
• D. Domain-based classification

Correct answer: C

Rationale: Rationale: A) Binomial nomenclature is a system used to give each organism a two-part scientific name (genus and species) but does not help in identifying or classifying organisms based on shared characteristics. B) Cladistics is a method of classification based on evolutionary relationships and shared characteristics, but it is not a tool used for identifying organisms. C) Dichotomous key is a tool that helps scientists identify and classify organisms based on their shared characteristics by presenting a series of choices leading the user to the correct identification. D) Domain-based classification is a system of classification that groups organisms into three domains (Bacteria, Archaea, Eukarya) based on molecular and genetic similarities, but it is not a tool used for identifying organisms based on shared characteristics.

6. What happens to the kinetic energy of an object when its velocity is doubled?

• A. Kinetic energy remains the same
• B. Kinetic energy is halved
• C. Kinetic energy doubles
• D. Kinetic energy quadruples

Correct answer: c

Rationale: Kinetic energy is directly proportional to the square of an object's velocity.
