Sarah remembered to use units this time, but added a second graph to distract you! Which of the Following is a piece of evidence about ENZYME A?

• The Enzyme only works at 40 degrees Celsius

• The Enzyme works best at temperatures below 20 degrees celsius

• The higher the temperatures, the faster the Reaction Rate

• Temperature directly affects the Reaction Rate of Enzyme A

For her final demonstration, Sarah added three data sets to the same graph; three enzymes found in humans. What conclusion could you draw from Sarah's graph?

• Each of these enzymes works best at a certain pH

• All enzymes operate best at a pH of 5

• pH does not impact enzyme activity

• Different areas of the digestive tract require different pHs to work best.

• Dissecting Microscope

• scanning electron microscope

• transmission electron microscope

Which microscope could be used to see a whole insect, like a bee, in greater detail?

• Dissecting Microscope

• Compound (Light) Microscope

• Scanning Electron Microscope

• Transmission Electron Microscope

True or False: Bubbles/min is measured on the X-axis of this graph

• True

• False

True or False: Depth is measured on the X-axis of this graph

• True

• False

Sarah forgot to add units to her graph, leaving both the X and Y axis without numbers. What can we still interpret from Sarah's Graph?

• The enzyme works best as a specific temperature

• The enzyme works best at all temperatures

• The enzyme activity is dependent on pH

• This enzyme would work for bacteria that live in volcanos and humans equally well

What is the optimal pH and Temperature for the "Relative Rate of Enzyme Reaction"

• 53 degrees celsius and a pH of 11

• 0 degrees celsius and a pH of 4

• 37 degrees celsius and a pH of 8

• 20 degrees celsius and a pH of 6

Which of these inferences BEST suits the graph of species 5?

• A population of bacteria goes through periods of activity and inactivity

• A population of mice increases and becomes stable

• A population of birds increases in the spring, but decrease 2 weeks later

• A population of wolves slowly increases and then rapidly increases

This graph shows how a population of whales has changed over many years. During this time, the whales were affected by a deadly disease with a very high death rate. Eventually, however, the population developed immunity to the virus.

which of these inferences is best supported by the graph?

• The predator population increased in 1993

• The ecosystem can on contain less than 85 whales

• The ecosystem is healthiest with a population below 75

• The population recovered in 1985 and 2001 from high death rates/population drops
