Test 4

Front

What is the condition of continuous movement but no overall change called?

Back

Dynamic equilibrium

Front

What is the active transport method that involves the engulfing of substances by the cell membrane?

Back

Endocytosis

Front

In a comparison of solutions, how can you determine which solution is more concentrated?

Back

The solution with the higher solute concentration is more concentrated.

Front

What is the term for the random motion of substances dissolved in water?

Back

Brownian motion

Front

What does the prefix 'phago-' mean in biological terms?

Back

To eat

Front

What is the difference between passive and active transport in cells?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of the cell membrane in transport processes?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the significance of dynamic equilibrium in biological systems?

Back

Dynamic equilibrium is important for maintaining stable conditions within cells and organisms despite ongoing processes.

Front

What is the process of exocytosis?

Back

Exocytosis is the process by which cells expel materials in vesicles that fuse with the cell membrane.
