For many young people today, shopping is their favourite free time activity. Why do you think this has happened? Should young people be encouraged to do different activities in their free time? Give reasons for your answer and include any relevant examples from your own experience or knowledge.

The results confirm my

hypothesis

. In my

hypothesis

, I predicted that increasing

stimulus

strength

will

increase

the

peak

of the

compound

action

potential. From the data collected, the

peak

of

CAP

increased from 0mVto 8mV when the

stimulus

strength

increased from 0mV to 400mV. The

hypothesis

is proved. A

compound

action

potential (

CAP

) is a signal recorded from a

nerve

bundle made up of many different individual

axons

. As the

stimulus

strength

increases, more

axons

are excited so the

peak

of

CAP

will

increase

(University of Queensland, 2022). As seen in figure 2, at low

stimulus

strength

like 20mV, there is little stimulation so no Na+ channels are opened and no Na+ will rush in, so there’s no

peak

of

CAP

and it is 0mV. At low

stimulus

strength

like 60mV, only a small number of

axons

is excited in the

nerve

, so the

peak

of

CAP

is so low which is 0.4mV.

In contrast

, when the

stimulus

strength

is high

like 180mV, all

Comparing the three groups, my

group

had the lowest

peak

CAP

with 8.9mV while

group

2 had the highest

with 12.99mV. For

latency

, my

group

got the highest

period with 1.08ms while

group

2 had the lowest with 0.98ms.

Latency

is the time between applying

stimulus

and the responses, so it refers to how quick the

nerve

responds to a

stimulus

. The reason for the differences in

CAP

and

could be because each
