Question

multiple choice question

the rhythmic muscular contractions that move a substance through a tract, such as food through the digestive tract and an ovum through a fallopian tube, is known as _______

osmosis
peristalsis
active transport
diffusion

Explanation:

Identify the biological process described

Using the Peristalsis Function knowledge point

• Peristalsis refers to the wave-like, involuntary muscular contractions that propel contents through tubular organs.
• This mechanism moves food through the digestive tract and assists in transporting an ovum through the fallopian tube.

Evaluate the alternative options

• Osmosis: The passive movement of water molecules across a semipermeable membrane.
• Active transport: The movement of substances across cell membranes against a concentration gradient using cellular energy (ATP).
• Diffusion: The passive movement of particles from an area of higher concentration to an area of lower concentration.

Answer:

• osmosis
• peristalsis (Correct answer)
• active transport
• diffusion
