Physics

1. What type of particle carries no charge and mediates the strong nuclear force between protons and neutrons?

Correct answer: C

Rationale: Gluons are the force carriers of the strong nuclear force, holding protons and neutrons together within the nucleus.

2. The "fight-or-flight" response is triggered by the hormone released from the:

Correct answer: B

Rationale: The correct answer is B: Adrenal glands. The "fight-or-flight" response is a physiological reaction that occurs in response to a perceived threat or danger. When this response is triggered, the adrenal glands release adrenaline, also known as epinephrine, into the bloodstream. This hormone prepares the body for action by increasing heart rate, dilating airways, and redirecting blood flow to essential organs. The thyroid gland (option A) primarily regulates metabolism, the pituitary gland (option C) controls many other hormone glands, and the pancreas (option D) is responsible for regulating blood sugar levels through the production of insulin and glucagon, but they are not directly involved in the fight-or-flight response.

3. What is the tough, fibrous tissue that connects bones at joints called?

Correct answer: B

Rationale: The correct answer is B: Ligaments. Ligaments are the tough, fibrous tissue that connects bones at joints. They provide stability and support to the joints, preventing excessive movement that could result in injury. Cartilage is a smooth, rubbery tissue that covers the ends of bones and cushions joints. Tendons are fibrous cords that attach muscles to bones, allowing for movement. Fascia is a connective tissue that surrounds muscles, groups of muscles, blood vessels, and nerves, providing support and protection. Therefore, in this case, the term that specifically refers to the tissue connecting bones at joints is ligaments.

Correct answer: C

Rationale: The direct object receives the action of the verb.

5. What does the term "dilution" refer to in a solution?

Rationale: Dilution involves adding more solvent to a solution to decrease the concentration of solute. The other choices do not accurately describe dilution

6. Which sentence uses the past perfect tense correctly?

Rationale: Option A expresses an action ("party began") completed before another past action ("I arrived").
