physics

1. How does an increase in mass affect the force required to produce the same acceleration on an object?

Correct answer: a

Rationale: With an increase in mass, more force is needed to produce the same acceleration due to inertia.

2. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

Correct answer: C

Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.

3. Lysosomes are known as "suicide bags" of the cell. What enzymes do they contain?

Correct answer: A

Rationale: Lysosomes are membrane-bound organelles containing hydrolytic enzymes responsible for breaking down various macromolecules, cellular waste, and foreign substances. These enzymes perform hydrolysis, a process where water molecules are used to break down larger molecules into smaller components. This function earned lysosomes the nickname 'suicide bags' as they can initiate cell death (apoptosis) by releasing their enzymes when needed. Ligases, transferases, and oxidoreductases are enzymes with different functions such as forming bonds, transferring molecules, and catalyzing redox reactions, respectively, which are not typically found in lysosomes. Therefore, the correct answer is A: 'Hydrolytic enzymes.'

4. Which of the following is the primary function of the lymphatic system?

Correct answer: B

Rationale: The correct answer is B: 'Carrying waste products away from tissues.' The primary function of the lymphatic system is to collect excess fluid from tissues and return it to the bloodstream, while also transporting waste products, pathogens, and cellular debris away from tissues to be filtered and eliminated. This helps maintain fluid balance in the body and supports the immune system by removing harmful substances. Options A, C, and D do not accurately describe the primary function of the lymphatic system, making them incorrect choices.

5. Which sentence uses parallel structure correctly?

Correct answer: B

Rationale: Parallel structure means using the same grammatical form for elements in a list. Option (b) uses parallel gerunds ("reading," "watching," "spending"), making it the correct choice.

6. What is the term for a solution with a pH value less than 7?

Correct answer: a

Rationale: Solutions with a pH less than 7 are acidic. The other choices do not accurately describe solutions with a pH less than 7.
