Question 1 of 5
Which of the following properties does soap, an emulsifier, have that make it useful for washing dirt off one's hands with water?
Correct Answer: A
Rationale: Soap acts as an emulsifier due to its dual polar (hydrophilic) and nonpolar (hydrophobic) nature, allowing it to effectively bond oil and water, making option A the correct choic

Question 2 of 5
Emphysema caused by damage to alveoli from toxins and pollutants is likely to result in the body having difficulty performing which of the following actions?
Correct Answer: A
Rationale: Emphysema is a condition that damages the alveoli in the lungs, leading to the loss of elasticity and reduced surface area for gas exchange. As a result, individuals with emphysema have difficulty in exchanging oxygen and carbon dioxide efficiently. The damage impairs the lung's ability to transfer oxygen from the air into the bloodstream and remove carbon dioxide from the body. Absorbing food (B), releasing histamine and acetylcholine (C), and producing enzymes (D) are not directly affected by emphysema.
Question 3 of 5
Which process involves the maturation and release of a representative egg from an ovarian follicle?
Correct Answer: C
Rationale: Ovulation is the process where a mature ovarian follicle releases an egg. This egg is the female gamete awaiting fertilization in the fallopian tube. Oogenesis refers to the complete process of egg cell development, fertilization is the merging of egg and sperm, and menstruation is the shedding of the uterine lining in the absence of pregnancy.
Question 4 of 5
Where are the tibia and fibula located in the body?
Correct Answer: C
Rationale: The tibia and fibula are located in the crural region of the body. The crural region, also known as the lower leg, is situated between the knee and the ankle. The tibia and fibula are the two bones found in this region and play a crucial role in the skeletal structure of the lower limb. The coxal region refers to the hip, the antecubital region is located at the front of the elbow, and the tarsal region pertains to the ankle area. Therefore, the correct answer is C, crural, as it specifically refers to the location of the tibia and fibula in the lower leg.
Question 5 of 5
htmlspecialchars(The mitochondrial inner membrane carries out the same functions in cellular respiration as the ......... membrane of chloroplasts in photosynthesis. Which of the following correctly completes the sentence above?)
Correct Answer: htmlspecialchars(C)
Rationale: htmlspecialchars(The correct answer is C - Thylakoid. The inner membrane of mitochondria is where cellular respiration occurs, just as the thylakoid membrane in chloroplasts is where photosynthesis takes place. These membranes are essential for energy production in their respective processes. Understanding the role of these membranes is crucial in comprehending how cells generate energy through cellular respiration and photosynthesis.)
