Why does the potato in a concentrated solution lose mass?

• The potato loses mass due to osmosis, as water moves out to the concentrated solution.
• The potato loses mass due to evaporation of water from its surface.
• The potato loses mass because it is cooked in the solution.
• The potato gains mass as it absorbs water from the concentrated solution.

What is Osmosis?

• Osmosis is the movement of nutrients into the bloodstream.
• Osmosis is the process of energy production in cells.
• Osmosis refers to the diffusion of gases in the atmosphere.
• Osmosis is the movement of water molecules through a semi-permeable membrane from a region of higher water concentration to a region of lower water concentration.

Name the types of variable in an experiment

• Independent variable, dependent variable, controlled variable
• Dependent factor, independent factor, variable factor
• Control variable, response variable, test variable
• Experimental variable, random variable, fixed variable

What is the function of Cell membrane?

• This is a partially permeable membrane that surrounds the cell and controls what enters and leaves the cell

• The cell membrane is responsible for energy production.
• The cell membrane stores genetic information.
• The cell membrane provides structural support to the cell.

Which organelle controls what goes in and out of a cell?

• Cell membrane
• Mitochondria
• Nucleus
• Ribosomes

what is the function of a nucleus?

• To produce energy for the cell
• The function of a nucleus is to store and manage genetic information and coordinate cellular activities.
• To transport nutrients within the cell
• To synthesize proteins

What is the function of the cytoplasm?

• A jelly-like substance where many of the cell's chemical reactions take place.

• The cytoplasm is primarily involved in protein synthesis.
• The cytoplasm is responsible for DNA replication.
• The cytoplasm acts as a barrier to protect the cell from external damage.

Where does most chemical reaction take place in a cell?

• Nucleus
• Mitochondria
• Ribosomes
• Cytoplasm

Describe the function of the mitochondria?

• Mitochondria are responsible for protein synthesis.
• Mitochondria store genetic information.
• Mitochondria regulate cell division.
• Where most of the reaction for aerobic respiration takes place
