Although now it causes more harm than good because it doesn't really have a purpose, it is believed it once was used for humans to digest bone.
Answer:
The phenomenon seen by the students is Osmosis.
Explanation:
Osmosis is the movement of molecules from higher concentration to lower concentration through a semi-permeable membrane. This type of movement of molecules occurs in the body cells. When the concentration of molecules is higher outside the cell than the inside, the molecules goes inside the cell through semi-permeable membrane.
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
Answer:
osmosis
Explanation:
The process that was going is <u>osmosis</u>.
<em>Osmosis is the movement of water molecules from regions of high water potential to regions of low water potentials through a selectively permeable membrane.</em>
In this case, the membrane is only permeable to water movement and not ions and water molecules move from the side with pure water (which happens to have higher water potential) to the side with 4% sodium chloride until equilibrium in water potential is established between the two sides.
