1. Which of the following lists best illustrates the idea of increasing levels of complexity?

• A. Cells, tissues, organelles, organs, organ systems
• B. Tissues, cells, organs, organelles, organ systems
• C. Organs, organelles, organ systems, cells, tissues
• D. Organelles, cells, tissues, organs, organ systems

Correct answer: D

Rationale: The correct answer is D: Organelles, cells, tissues, organs, organ systems. This list correctly depicts the increasing levels of complexity in biological organization. It starts with organelles, which are subunits within cells, followed by cells, then tissues (groups of cells working together), organs (comprised of different tissues), and finally organ systems (multiple organs working together). Choices A, B, and C are incorrect as they do not follow the logical progression of complexity from smaller units to larger, more complex structures.

2. Temperature is a form of energy, whereas heat is a measurement of the intensity of the temperature.

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The statement is true. Temperature is a measure of the average kinetic energy of the particles in a substance, while heat is the transfer of energy from a hotter object to a colder one. Heat is not a measurement of the intensity of temperature, but rather the energy transfer due to a temperature difference. Therefore, the correct answer is True. Choice B (False) is incorrect as the statement is true based on the definitions of temperature and heat.

3. Which of the following is not part of the female reproductive system?

• A. The uterus
• B. The uterine tube
• C. The vulva
• D. The bulbourethral gland

Correct answer: D

Rationale: The bulbourethral gland is not part of the female reproductive system. This gland is part of the male reproductive system and is responsible for producing a clear fluid that helps in lubrication during sexual activity. Choices A, B, and C are part of the female reproductive system. The uterus is where a fertilized egg implants and develops into a fetus. The uterine tube (fallopian tube) transports eggs from the ovary to the uterus. The vulva includes the external genital organs of the female.

4. Which of the following characteristics of life and their descriptions are correct?

• A. Responsiveness - detecting and responding to changes in the environment
• B. Assimilation - incorporating absorbed substances into the body
• C. Respiration - obtaining energy from food molecules through oxygen
• D. Circulation - the movement of substances in body fluids

Correct answer: D

Rationale: The correct answer is D: Circulation - the movement of substances in body fluids. Circulation refers to the movement of substances like nutrients, gases, and wastes in body fluids to and from cells. Choice A is incorrect because responsiveness is about detecting and responding to changes in the environment, not obtaining and using oxygen. Choice B is incorrect because assimilation is the process of incorporating absorbed substances into the body, not changing them into chemically different forms. Choice C is incorrect because respiration is the process of obtaining energy from food molecules through oxygen, not the obtaining and using oxygen itself.

5. What function is associated with the dermal layer of the skin?

• A. Sensory perception
• B. To provide support and structure to the skin
• C. Protection from UV rays
• D. Insulation

Correct answer: B

Rationale: The correct function associated with the dermal layer of the skin is to provide support and structure to the skin. The dermis is the thickest layer of the skin and is responsible for maintaining the skin's integrity and firmness. Choices A, C, and D are incorrect as sensory perception, protection from UV rays, and insulation are functions associated with other layers of the skin, such as the epidermis and subcutaneous tissue.
