1. Nervous tissue is responsible for

• A. Movement
• B. Protection
• C. Communication and coordination
• D. Nutrient transport

Correct answer: C

Rationale: Nervous tissue is responsible for communication and coordination within the body. This tissue includes neurons and supporting cells, which work together to transmit electrical signals and information throughout the body. Movement is primarily controlled by the muscular system, protection is the role of the immune system and skin, while nutrient transport is primarily handled by the circulatory system. Therefore, the correct answer is C: 'Communication and coordination.'

2. Which hormone is responsible for regulating blood sugar levels and is produced by the pancreas?

• A. Insulin
• B. Glucagon
• C. Testosterone
• D. Estrogen

Correct answer: A

Rationale: The correct answer is A: Insulin. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. When blood sugar levels rise after a meal, insulin is released to help cells absorb glucose for energy or storage. This process helps to lower blood sugar levels. Glucagon, the hormone mentioned in option B, is also produced by the pancreas but has the opposite effect of raising blood sugar levels when they are too low. Testosterone and estrogen, options C and D, are sex hormones and are not directly involved in regulating blood sugar levels.

3. What is the process of cells dividing to produce new cells called?

• A. Cell division
• B. Cell differentiation
• C. Cell growth
• D. Cell regeneration

Correct answer: A

Rationale: Rationale: A) Cell division is the process by which a parent cell divides into two or more daughter cells, allowing for growth, repair, and reproduction in living organisms. This process ensures that genetic material is accurately passed on to the new cells. B) Cell differentiation refers to the process by which cells become specialized to perform specific functions in an organism. While cell division is essential for cell differentiation, they are distinct processes. C) Cell growth is the increase in size or mass of a cell, which can occur before or after cell division. While cell growth is a component of the cell division process, it is not the primary process of cells dividing to produce new cells. D) Cell regeneration is the process by which damaged or lost cells are replaced by new cells. While cell division is involved in cell regeneration, it specifically refers to the overall process of cells dividing to produce new cells. Therefore, the most appropriate answer to the ques

4. What property of a wave determines the loudness of sound when heard by the human ear?

• A. Frequency
• B. Amplitude
• C. Wavelength
• D. Velocity

Correct answer: b

Rationale: The amplitude of a sound wave correlates with its perceived loudness by the human ear.

5. The student studies diligently for her upcoming exam. Which word is the plural form of "study"?

• A. studies
• B. studying
• C. studied
• D. studier

Correct answer: C

Rationale: The plural form of a noun refers to more than one of that thing.

6. What is the relationship between work and the displacement of an object?

• A. Work depends only on the force applied, not displacement
• B. Work is directly proportional to displacement
• C. Work is inversely proportional to displacement
• D. Work is unrelated to displacement

Correct answer:

Rationale: Work done is directly proportional to the displacement of an object in the direction of the force applied.
