Anatomy

1. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?

Correct answer: B

Rationale: The correct answer is B: Amylase (carbohydrate digestion). The pancreas produces digestive enzymes that aid in breaking down food components. Trypsin is produced by the pancreas for protein digestion, lipase for fat digestion, and lactase is an enzyme produced in the small intestine for breaking down lactose (sugar). Amylase, on the other hand, is primarily produced in the salivary glands and the pancreas to break down carbohydrates into simple sugars. Therefore, amylase is not a pancreatic enzyme for digestion, making it the correct answer in this question.

2. Which type of orbital can hold a maximum of 10 electrons?

Correct answer: D

Rationale: Each f orbital can hold up to 2 electrons, and there are 5 f orbitals, totaling a maximum of 10 electrons.

3. Which type of reaction is represented by the equation A + B → AB?

Correct answer: a

Rationale: Synthesis reactions involve the combination of two or more substances to form a new compound.

4. Within a nuclear reactor, control rods serve the primary purpose of:

Correct answer: C

Rationale: Control rods within a nuclear reactor serve the primary purpose of absorbing excess neutrons to control criticality. By adjusting the position of the control rods, the reactor operators can regulate the rate of fission reactions and prevent the reactor from overheating or reaching a state of uncontrolled chain reaction. Reflecting neutrons back into the core and moderating the velocity of neutrons are not the primary functions of control rods. Reflectors are used to bounce neutrons back into the core, while moderators slow down fast neutrons to increase the likelihood of fission. Therefore, the correct answer is B: 'Absorbing excess neutrons to control criticality.'

5. What is the largest muscle in the human body?

Correct answer: A

Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.

6. A child's toy block is a cube with side lengths of 5cm. What is its total surface area?

Correct answer: D

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