Biology Graphs

Which would go on the y-axis?

• Time

• # of Bacteria 

In living cells, enzymes act as catalysts, which may reduce the amount of activation energy required for a chemical reaction to occur. In the graphs below, pathway x is a solid line representing the uncatalyzed reaction. The dotted line shows the catalyzed reaction. Which graph best illustrates the changes in a reaction when the catalyst reduces the amount of energy required?

• A

• B

• C

• D

Answer explanation

Both lines begin at the same level but the catalyzed reaction shows a decrease in the activation energy...

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

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

In Biology, a scatter plot showing a downward trend indicates:

• A positive correlation

• A negative correlation

• No correlation

• A causal relationship

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.

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

Tadpoles, the infant state of frogs, sometimes eat foods that adult frogs do not. One such example is algae with the chemical AlphaBeta. A scientist has measured the amounts of AlphaBeta in algae and in ADULT frogs to try and prove that the chemical sticks around even after the tadpoles grow into frogs. Which piece of evidence from the graph SUPPORTS this conclusion?

• The AlphaBeta has made the algae and frogs grow bigger

• The AlphaBeta concentration in algae is related to the algae concentration in frogs

• The amount of AlphaBeta in algae and frogs are unrelated

Ending with a familiar graph. What is the BEST conclusion that can be drawn directly from this data?

• Embanked ponds produce healthier damselflies

• Protozoa infection isn't dependent on pond type

• The rate of infection in Creek-fed ponds has remained constant

• The rate of infection in embanked-fed ponds has increased over time
