1. Cells do not aggregate into organelles based on similar functions.

Correct answer: B

Rationale: The statement is false. Cells with similar functions do not aggregate into organelles. Organelles are specialized structures within cells that perform specific functions, such as the nucleus, mitochondria, and endoplasmic reticulum. Cells themselves are the basic structural and functional units of organisms, and organelles are located within cells to carry out various tasks. Therefore, cells do not aggregate into organelles, but organelles are found within cells to support their functions. Choices A, C, and D are incorrect as cells do not form organelles by aggregating based on similar functions.

2. Which part of the nephron is closest to the collecting duct?

Correct answer: A

Rationale: The correct answer is the Distal convoluted tubule (DCT). The DCT is the part of the nephron closest to the collecting duct, where the final adjustments to electrolyte and fluid balance are made. Bowman's Capsule is located at the beginning of the nephron, where filtration of blood occurs. The Afferent Arteriole brings blood to the glomerulus for filtration. The Proximal Convoluted Tubule (PCT) is situated after the Bowman's Capsule and is not the part closest to the collecting duct.

3. Which of the following statements is true concerning the female reproductive system?

Correct answer: D

Rationale: The correct answer is 'All of the above.' The female reproductive system produces female sex cells (eggs), transports them through the fallopian tubes, and can support the development of an embryo through the uterus. Choice A is correct because the ovaries produce eggs, choice B is correct as the fallopian tubes transport the eggs, and choice C is correct as the uterus provides the environment for the embryo to develop. Therefore, all of these statements are true regarding the female reproductive system.

4. Which of the following bones is a component of the appendicular skeleton?

Correct answer: B

Rationale: The correct answer is B: Symphysis pubis. The symphysis pubis is a component of the appendicular skeleton, specifically part of the pelvic girdle. The xiphoid process (Choice A) is part of the axial skeleton, located at the lower end of the sternum. The sacrum (Choice C) is also part of the axial skeleton, forming the posterior part of the pelvis. The sternum (Choice D) is part of the axial skeleton, located in the center of the chest.

5. An occurrence of too high a concentration of which of the following electrolytes is associated with cardiac arrhythmias?

Correct answer: C

Rationale: The correct answer is potassium. High levels of potassium in the blood, known as hyperkalemia, can lead to cardiac arrhythmias by affecting the electrical activity of the heart. This can disrupt the normal rhythm of the heart and lead to serious complications. Chloride, phosphorus, and sodium imbalances are not typically associated with cardiac arrhythmias, making them incorrect choices.
