Question
A study examined the effects of four weeks of intensive training in athletes on vertical jumping performance and neuromuscular learning. The graph shows the results for jumping height.
Outline the effect of training on jumping performance.
List the different types of neurons involved in a reflex arc.

Using an example, describe how innate behaviour may increase the chances of survival of a species.
Markscheme
a. jumping performance shows an improvement «during the first two/three weeks»
