Question 1 of 5

Which of the following terms refers to the ability to detect and respond to changes in the internal and external environment?

Correct Answer: B

Rationale: Responsiveness is the correct term that refers to the ability to detect and respond to changes in the internal and external environment. In this context, growth is incorrect as it pertains to an increase in size or number, reproduction involves producing offspring, and development refers to the process of growth, maturation, and differentiation of cells and tissues. Therefore, 'Responsiveness' is the most appropriate term for the given description.

Question 2 of 5

What is the term for the division of the cytoplasm?

Correct Answer: A

Rationale: Cytokinesis is the correct term for the division of the cytoplasm during cell division. It is the final stage of cell division, following either mitosis or meiosis, where the cytoplasm of a parent cell is divided into two daughter cells. Mitosis is the process of nuclear division, while meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes of the parent cell. Apoptosis, on the other hand, is programmed cell death and not the division of the cytoplasm.

Question 3 of 5

Which statement about white blood cells is true?

Correct Answer: A

Rationale: The correct answer is A: B cells, a type of white blood cell, are responsible for producing antibodies in response to pathogens. Antibodies play a crucial role in identifying and neutralizing foreign substances like bacteria and viruses in the body, aiding in the immune response and protecting against infections. This function is essential for maintaining a healthy immune system. White blood cells, including B cells, are produced in the bone marrow before entering the bloodstream. Platelets, not white blood cells, are a specialized class of blood cells that function to clot blood and stop bleeding. While white blood cells provide immunity, not all of them are active throughout life as some have specific lifespans and functions.

Question 4 of 5

Which of the following are functions of the urinary system?

Correct Answer: D

Rationale: The corrected answer is D, 'All of the above.' The urinary system performs multiple essential functions to maintain the body's internal environment. Synthesizing calcitriol and secreting erythropoietin are crucial roles of the kidneys. Regulating the concentrations of sodium, potassium, chloride, calcium, and other ions helps in maintaining the electrolyte balance. Reabsorbing or secreting hydrogen ions and bicarbonate is vital for managing the body's acid-base balance. Furthermore, the urinary system is involved in detecting reductions in blood volume and pressure, aiding in the maintenance of blood pressure levels and fluid balance in the body.

Question 5 of 5

Which cellular organelle is used for digestion to recycle materials?

Correct Answer: B

Rationale: The lysosome is the correct cellular organelle used for digestion to recycle materials. Lysosomes contain enzymes that break down waste materials, cellular debris, and ingested substances. This process helps in recycling nutrients and maintaining cellular homeostasis. The Golgi apparatus is involved in processing and packaging proteins, the centrioles play a role in cell division, and the mitochondria are responsible for energy production. However, none of these organelles are primarily used for digestion and recycling of materials within the cell.
