What is the purpose of chemosynthesis? (Why is it needed?)
Use chemical (inorganic molecules) and convert them to glucose (organic molecule)

What is the function of DNA?
Store and transmit genetic information by telling cells what proteins to make and when to make them
200
Name The Characteristic: Organisms make more of their own kind from one generation to the next
Reproduction

What are the sides (backbone) of the DNA molecule made up of?
Repeating deoxyribose sugar and phosphate molecules
300
Living things _____ ____ _____in their environment. EX. Sunflowers move towards the sunlight.
Respond To Stimuli
300
What does an enzyme do in a reaction?
Speeds up
300
What organelle...layers around a cell and regulates what goes in and out of the cell
Cell Membrane
300
What is the effect on the rate of photosynthesis based on light intensity?
As the light intensity increases, so does the rate of photosynthesis. However, this is to a certain point. After which the absorption of light by pigments maxes out. However, the higher light intensities DO NOT cause the rate of photosynthesis to decrease-it just will not increase past this point of light absorption
300
What are the steps (or rungs) of the DNA molecule made up of?
Nitrogen base pairs (Adenine bound to Thymine and Cytosine bound to Guanine)
400
Name The Characteristic: EX. Organisms were able to adapt over time, moving from sea to land
Change Overtime/Evolution
400
Define surface tension.
caused by cohesion of water molecules creating hydrogen bonds where the surface of water creates an elastic-like condition allowing certain organisms to actually stride on the water's surface. (Something around that)

What would happen if people didn’t have lysosomes?
Decreased ability of the immune system(answers may vary)
