The process by which bile breaks down large lipid globules into smaller lipid globules in small intestine is called ______

A. Final synthesis step of vitamin K production: The final (and major) synthesis of vitamin K is by gut bacteria and liver processes; the urinary system (kidneys) is not the final synthesis site for vitamin K .
B. Filters the blood, removing wastes: The kidneys filter blood plasma (glomerular filtration) to remove metabolic wastes and excess substances .
C. Regulates the pH of the body: The kidneys conserve or excrete H⁺ and bicarbonate and so play a central role in acid–base balance .
D. Excretion of wastes: By forming urine and eliminating nitrogenous wastes and excess electrolytes/fluid, the urinary system excretes metabolic wastes .

A. Diffusion of gas does not depend on the partial pressure gradient: Incorrect -gas diffusion across membranes depends on partial pressure gradients (and membrane properties).
B. Gas diffuses from high partial pressure to low partial pressure: Correct -diffusion follows the partial pressure gradient (for example O₂ moves from alveoli where PO₂ is higher into blood where PO₂ is lower).
C. Gas diffuses from low partial pressure to high partial pressure: Incorrect -that direction would require active transport; gases passively diffuse down their gradients.
D. Equilibrium can be reached without partial pressure gradient: Incorrect -equilibrium is reached when partial pressures equalize; without a gradient diffusion won’t proceed.
