Deduce whether there is a correlation between the neural traces and the percentage of responding G1 neurons.
[2]
a. there is a positive relationship/correlation between the size of neural traces and the percentage of responding G1 neurons Accept vice versa
OR
the chemicals that cause stronger/higher neural traces also cause the greatest percentage of responding G1 neurons ✔
b. fox and stoat scents have «approximately» the same/similar neural traces and the same percentage of responding neurons/>75 % ✔
c. mouse alarm compounds cause smaller neural traces and smaller percentage of responding neurons/25–75 % ✔
d. control chemicals have no response in both cases
OR
no percentage of «G1 neurons» response and no action potential «in neural traces» ✔
Similarly, in 1f most could see the positive correlation, albeit not stating it, between the size of the trace and the percentage of responding G1 neurons.
