Use the planner on this page: pick your exam and the hours you have each week, and it spreads them over the seven topics by their share of the test and how sure you feel, with timed checks in the final weeks.

Try 2 questions

Question 1
Carbon dioxide released in the dark (mL per hour)
ContentsAt 10 degrees CelsiusAt 25 degrees Celsius
germinating peas0.61.5
dry peas0.10.1
glass beads00
Students measured the carbon dioxide released by germinating peas, dry peas and glass beads, all in the dark, at two temperatures (an invented data set). Which conclusion is best supported by the table?
Question 2
Percent of wood frog tadpoles that survived
Where the eggs came fromSurvival at pH 4.5 (%)Survival at pH 7.0 (%)
acid ponds7290
neutral ponds1892
Some ponds in the Adirondacks are much more acidic than others. Biologists collected wood frog eggs from acidic ponds and from neutral ponds and raised all the tadpoles in the same laboratory, at pH 4.5 or at pH 7.0 (a hypothetical study). The table shows the percent of tadpoles that survived. Which conclusion is best supported?
