physics

1. What does the term "terminal velocity" refer to in physics?

Correct answer: a

Rationale: Terminal velocity is the constant velocity achieved by an object falling through the atmosphere when the force of air resistance equals the force of gravity.

2. The intricate network of blood vessels responsible for transporting blood throughout the body is the:

Correct answer: B

Rationale: The correct answer is B: Circulatory system. The circulatory system is responsible for transporting blood, oxygen, nutrients, and other substances throughout the body. It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. The lymphatic system (A) is a separate system that helps to maintain fluid balance in the body and plays a role in the immune response. The nervous system (C) is responsible for transmitting signals between different parts of the body and the brain. The respiratory system (D) is responsible for the exchange of oxygen and carbon dioxide in the body through breathing. In this question, the circulatory system is specifically mentioned as the network of blood vessels responsible for transporting blood, making it the correct answer.

3. Which preposition best completes the sentence: "She borrowed money _____ her friend."

Correct answer: B

Rationale: "From" indicates the source of the borrowed money.

4. What checkpoint mechanism ensures all chromosomes are attached to the spindle fibers before anaphase begins?

Correct answer: A

Rationale: Rationale: A) Prometaphase is the correct answer because it is the stage of mitosis where all chromosomes are attached to the spindle fibers before anaphase begins. During prometaphase, the nuclear envelope breaks down, allowing the spindle fibers to attach to the kinetochores of the chromosomes. This attachment is necessary for proper chromosome alignment and segregation during anaphase. B) Metaphase is incorrect because it is the stage where chromosomes are aligned at the metaphase plate but do not necessarily have all spindle fibers attached. C) Cyclin degradation is incorrect because it is a regulatory mechanism that controls the progression of the cell cycle but is not specifically related to ensuring all chromosomes are attached to spindle fibers. D) Sister chromatid cohesion is incorrect because it refers to the physical connection between sister chromatids that is maintained until anaphase, but it does not ensure that all chromosomes are attached to spindle fibers.

5. Which type of energy is associated with the random motion of particles in a substance?

Correct answer: c

Rationale: Thermal energy is related to the random motion of particles in a substance and is associated with temperature.

6. Bone is a type of

Correct answer: C

Rationale: The correct answer is C: "Hard connective tissue." Bone is classified as hard connective tissue because it is composed of cells embedded in a matrix of mineralized collagen fibers, providing support and protection to the body. Epithelial tissue (A) covers body surfaces and lines cavities, while connective tissue (B) includes bone, cartilage, and blood. Muscle tissue (D) is responsible for movement and is not the same as bone tissue.
