1. What is a group of organisms of the same species living in a particular area called?

• A. Community
• B. Population
• C. Ecosystem
• D. Habitat

Correct answer: B

Rationale: Rationale: A) Community refers to all the populations of different species living and interacting in a particular area. Since the question specifies organisms of the same species, community is not the correct answer. B) Population is a group of organisms of the same species living in a particular area. This term specifically refers to individuals of the same species and their interactions within a defined area. C) Ecosystem includes all the living organisms (biotic factors) and non-living components (abiotic factors) in a particular area and their interactions. While populations are part of an ecosystem, the term "ecosystem" is broader and includes multiple populations. D) Habitat refers to the specific environment where an organism lives, including the physical and biological factors. It is the place where a population or individual organism resides, but it does not specifically refer to a group of organisms of the same species.

2. Identify the bone with the greatest length in the human body.

• A. Femur (Thigh bone)
• B. Humerus (Upper arm bone)
• C. Tibia (Shin bone)
• D. Scapula (Shoulder blade)

Correct answer: A

Rationale: The femur, exceeding a meter in length, bears significant weight and enables locomotion.

3. Which part of the nervous system is responsible for transmitting signals from the sensory organs to the central nervous system?

• A. Autonomic nervous system
• B. Somatic nervous system
• C. Peripheral nervous system
• D. Central nervous system

Correct answer: C

Rationale: The correct answer is C: Peripheral nervous system. The peripheral nervous system is responsible for transmitting signals from the sensory organs to the central nervous system. It consists of nerves outside of the brain and spinal cord that carry information to and from the central nervous system. The autonomic nervous system (A) regulates internal bodily functions, the somatic nervous system (B) controls voluntary movements, and the central nervous system (D) includes the brain and spinal cord where processing of signals occurs, rather than transmitting signals from the sensory organs.

4. The pancreas secretes digestive enzymes into the small intestine. What enzyme breaks down proteins into amino acids?

• A. Pepsin
• B. Lipase
• C. Amylase
• D. Trypsin

Correct answer: D

Rationale: The correct answer is D: Trypsin. Trypsin is an enzyme produced by the pancreas and secreted into the small intestine where it plays a key role in breaking down proteins into smaller peptides and amino acids. Pepsin is produced in the stomach and specifically acts on protein, not in the small intestine. Lipase is an enzyme that breaks down fats, not proteins. Amylase is an enzyme that breaks down carbohydrates, not proteins. Therefore, Trypsin is the enzyme responsible for breaking down proteins into amino acids in the small intestine.

5. Which term describes the ability of a substance to conduct electricity?

• A. Reactivity
• B. Density
• C. Conductivity
• D. Viscosity

Correct answer: c

Rationale: Conductivity refers to a substance's ability to conduct electricity. Substances that conduct electricity well are known as conductors.

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

• A. Adding more solvent to decrease concentration
• B. Adding more solute to increase concentration
• C. Reducing the temperature to increase solubility
• D. Increasing pressure to increase solubility

Correct answer: A

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