1
Q
Why is a choice chamber set up?
A
to show different environments and demonstrate kinesis in woodlice, as they change direction and move faster in unfavourable environments (lighter, drier)
2
Q
How can you determine whether the observed results differ from the expected results in choice chamber?
A
use chi squared test
3
Q
How can you determine the glucose concentration in a sample?
A
measure absorbance of sample - using calibration curve, find glucose concentration
