Which of the following best describes the difference between infiltration and ventilation in biological systems?
A
Infiltration refers to the movement of water into soil, while ventilation refers to the movement of air in and out of the lungs.
B
Infiltration is the exchange of gases in the alveoli, while ventilation is the movement of nutrients through the phloem.
C
Infiltration is the process of oxygen binding to hemoglobin, while ventilation is the process of water absorption by roots.
D
Infiltration and ventilation both refer to the movement of blood through the circulatory system.
Verified step by step guidance1
Step 1: Begin by understanding the definitions of the terms 'infiltration' and 'ventilation' in biological contexts. Infiltration generally refers to the movement of substances like water into soil, while ventilation refers to the movement of air in and out of the lungs in animals.
Step 2: Analyze the options provided in the question. Each option pairs infiltration and ventilation with different biological processes. Carefully evaluate whether the processes described align with the definitions of the terms.
Step 3: Eliminate options that incorrectly describe infiltration and ventilation. For example, infiltration does not refer to gas exchange in alveoli or oxygen binding to hemoglobin, and ventilation does not involve nutrient movement through the phloem or water absorption by roots.
Step 4: Focus on the correct pairing of infiltration and ventilation. Infiltration is a term used in environmental science to describe water movement into soil, while ventilation is a physiological process describing air movement in and out of the lungs.
Step 5: Confirm that the correct answer is the option stating: 'Infiltration refers to the movement of water into soil, while ventilation refers to the movement of air in and out of the lungs.' This aligns with the definitions and biological contexts of the terms.
