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

Spontaneous Generation implied what, and who conclusively
disproved it?
Life growing out of the non-living, Pasteur
Abiogenesis, Saweczko
Dead material coming back to life, Beattie
Biogenesis, Needham
Life only from living things, Redi Abiogenesis is another term for spontaneous generation. Pasteur proved Redi’s theory by conclusively allowing air but not micro-organisms to reach a dead carcass where nothing grew.

The chloroplast is for photosynthesis, the vacuole is to generate turgor pressure, and the wall helps hold that pressure. Only animals have centrioles for reproduction and lysosomes for digestion

The process of water moving across a selectively permeable
membrane is
Osmosis
Passive Transport
Active Transport
Hydrolysis
Diffusion
Osmosis is a specific case of diffusion. Both are types of passive transport.

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.

bilayer:

The polar tail

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.

The two parts to a virus are
Capsid and genetic material
