The graph shows that peas that have been germinating for three days consume more oxygen during a 30-minute period than peas that have been germinating for one day.
During this time you should read the questions and create short outlines to guide your responses.
To make the most of these practice questions, take 5 to 10 minutes to read the questions and create an outline.
After a 10-minute equilibration period, I will begin to measure the amount of oxygen consumed at 10-minute intervals for 30 minutes.
I will record results measured by the graduated intervals on the pipette attached to the respirometer.(B) Key points to include: labels on each axis, regular intervals on the graph, a specific title on the graph, points plotted on the graph, and a line connecting the appropriate points.
These long series of base pairs code for longer and more complex proteins that can differ in minor or very significant ways.
For example, sickle cell anemia is caused by only one base pair difference in the genetic code for hemoglobin, but this base pair causes an incredible difference in the function of the protein.
Identify, isolate, and test one experimental variable in your experiment.
Identify any variables that you must control, and explain the apparatus that you will use to measure the cellular respiration.
You should immediately realize that this is a question about cellular respiration.
You should draw on your knowledge of this topic to answer the question.
