Lipid Bilayer

Multiple Select

What is a lipid bilayer? 3 correct answers

• it is the one layer of fatty acids that surrounds cells and is hydrophobic

• it is two layers of fatty acids that surround a cell

• A layer that keeps water from leaving the cell

• a Layer that keeps water from entering a cell.

Multiple Select

diffusion is : (more than one answer)

• when when a solute (what gets dissolved) goes from a high to a low concentration

• a system of balance called homeostasis

• a system of homeostasis that does not require energy

• uses a solvent (what dissolves liquids or solids) to maintain homeostasis with no energy needed

Multiple Select

Facilitated Diffusion is: 3 answers

• When molecules ride on other molecules to move around

• When molecules move around but dont use their own energy

• when molecules are large

• when molecules piggyback on another molecule

Multiple Choice

What is meant by saying water is a solvent?

• somethings are afraid of water: hydrophobic

• somethings like water :hydrophilic

• water can dissolve liquids and solids

• water is needed for cells to live

Multiple Select

The presences of water in a cell makes it easier for:

• nutrients (food) to move around easier

• oxygen to move around easier

• water can easily enter and leave a cell.

• water is not needed

• A system that can go from low concentration to low

Multiple Select

Active transport gets its energy from: (3 answers)

Multiple Choice

In active transport these are needed:

• brakes

• hydrophilic

• hydrophobic

• The use of Vacuoles (pockets) to move molecules in and out

• hydrophobic

Multiple Select

The role of transporter proteins is: (2 answers)

• to move molecules into a cell
