What happens to a person!s heart rate as the person increases his or her activity level?

Frequent exercise will cause your heart to grow stronger, making it easier for it to distribute blood throughout your body. A stronger heart means that each time your heart beats, it pumps more and more blood throughout you body. This allows your heart to beat less, while still distributing the same amount of blood.

Their heart rate increases. Systolic increases and diastolic stays the same.

Explanation:

In a fractional banking system, banks are required to maintain  a proportion of  their total deposit for precautionary reasons by banking authority.

The proportion is known as the required reserve ratio and is always given as a percentage of the total deposit.

The required reserve = required reserve (%) × Total deposit

                                  = 12%× 300 million

                                   =36  million

 Required reserve=$36  million
