The

Biological Trivia Network

How to play

• Each team needs 5 large (8.5 x 11) sheets to indicate their choice:– One each marked A, B, C, D, and E

• For each question, raise the sheet corresponding to the choice you believe is correct

• You may change you answer at any time• The point value decreases with time• The teacher will award points to each group

based on when the correct answer was raised

disproved it?

Life growing out of the non-living, Pasteur

Abiogenesis, Saweczko

Dead material coming back to life, Beattie

The process of water moving across a selectively permeable

The hydrophilic water loving phosphate heads make up the outside layer, the portion in contact with the liquid environment. The hydrophobic lipid tails face each other to get away from the liquid environment.

Dynamic Equilibrium implies

Balance but with particles moving

A stable sloping slide

A changing concentration gradient

Imbalance with particles moving

Balance with particles not moving Diffusion and Osmosis occur because of a difference in concentration in two different areas and the fact that particles are always moving. Equilibrium is achieved when the concentrations become equal, but the particles still always move

A

B

C

D

E

Hypotonic – less solute concentration in the solution

This causes water from the solution to go into the cell to balance the concentrations

20001500 1000500

What type of solution is the cell in and what will happen:

Hypotonic, cell will grow

Hypo-osmotic, cell will divide

Hypertonic, cell will grow

Hypotonic, cell will shrink

Hypertonic, cell will shrink

A

This is active transport because the cell uses energy to move the molecules. It is exo because it is going out of the cell.
