Time PeriodA- Sleeping

Time PeriodB-Walking

Time Period C- Running

Time Period D-Walking

Time Period E- Frightened by a loud Noise

Explanation:

The question is asking you to label the time periods shown with the activity that represents the heart rate of the person.

Your heart rate is lowest when you're sleeping because your body is not exercising or under any stress

When you're walking your heart rate will steadily go up but not as high as running because running requires more work and physical strain than walking

Your brain is under extreme stress when you are startled by a loud noise which causes a spike in heart rate.

Boooomer

Answer:

The answer is a

Explanation:

It is not b because when someone is frighented by a sudden loud noise the heart rate will be very pointy.

Not c either because sleeping makes your heart rate very low.

Not d because waking make your heart rate increase (about 90 beats per minute) but then stay in the same rate.

So probably a because running increases your heart rate at a very big level for a long time but then it drop when you stop.

Hope this helps!
