1. Which division of the peripheral nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling voluntary muscle movements?

Correct answer: a

Rationale: The correct answer is A: Somatic nervous system. The somatic nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, allowing for voluntary muscle movements. This division controls conscious movements such as walking, talking, and picking up objects. The autonomic nervous system (option B) controls involuntary functions like heart rate and digestion, while the sympathetic (option C) and parasympathetic (option D) nervous systems are subcategories of the autonomic system and regulate the body's responses to stress and relaxation, respectively. Therefore, the somatic nervous system is the correct division responsible for voluntary muscle movements.

2. The human body's largest organ, responsible for detoxification and a multitude of other functions, is the:

Correct answer: B

Rationale: The correct answer is B: Liver. The liver is the largest internal organ in the human body and is responsible for detoxification, processing nutrients, producing bile, and regulating blood sugar levels, among other functions. While the heart is vital for pumping blood, the lungs are crucial for respiration, and the skin is the body's largest external organ, the liver plays a central role in detoxification and various metabolic processes, making it the correct answer to this question.

3. What are the key differences between cytokinesis in plant and animal cells?

Correct answer: B

Rationale: Rationale: A) Animal cells utilize an actomyosin ring for cleavage furrow formation, while plant cells lack this mechanism. - This statement is true. Animal cells use an actomyosin ring to form a cleavage furrow during cytokinesis, while plant cells do not have this mechanism. Instead, plant cells form a cell plate. B) Plant cells rely on the assembly of a cell plate in the center of the dividing cell, ultimately separating the cytoplasm. - This statement is correct. Plant cells form a cell plate in the middle of the dividing cell during cytokinesis. The cell plate eventually develops into a new cell wall that separates the two daughter cells. C) Cytokinesis in both plant and animal cells is driven by the expansion of the endoplasmic reticulum. - This

4. What is the scientific name for the common housefly?

Correct answer: A

Rationale: Rationale: - Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. - Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. - Apis mellifera (option C) is the scientific name for the western honeybee. - Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

5. Which element is used in insulin and promotes glucose uptake into cells for energy production?

Correct answer: B

Rationale: Chromium aids in insulin's function, enhancing glucose uptake by cells and regulating blood sugar levels.

6. What type of bond involves the complete transfer of electrons between atoms?

Correct answer: B

Rationale: Ionic bond - Electrons are completely transferred from one atom to another, creating cations and anions with strong electrostatic attraction.
