Answer:
A 17 year old with a resting heart rate of 62 bpm has a maximum hearth rate of 203 bpm, a hearth rate reserve of 141 bpm and target hearth rate between 161 and 182 bpm
Explanation:
Target heart rate is a measure used to calculate the range of heart rate that should be maintained during intense exercise.
Knowing a person's age and resting heart rate (RHR), a target heart rate calculation can be made from the maximum heart rate (MHR) and the hearth rate reserve (HRR)
Data:
- Age: 17 years old
- RHR: 68 bpm
The maximum heart rate is calculated by subtracting age from a constant value of 220, so:
- MHR = 220 - age
- MHR = 220 - 17
- MHR = 203 bpm
HRR is calculated by subtracting the resting heart rate (RHR) from the MHR value:
- HRR = MHR - RHR
- HRR = 203 - 62
- HRR = 141 bpm
THR is obtained by multiplying the HRR by 0.7 and 0.85, to obtain the range of heart rate in which the exercise can be performed.
- THR lower limit = (HRR x 0.7) + RHR Lower THR = (141 x 0.7) + 62 = 160.7 ≈ 161 bpm
- THR top limit = (HRR x 0.85) + RHR THR top = (141 x 0.85) + 62 = 181,85 ≈ 182 bpm
For the 17-year-old, the ideal target heart rate for an intense exercise is between the values of 161 and 182 bpm.
Organs I guess.

The correct answer is A) microorganisms are transmitted from one organism to another.
The chain of infection is a process in which microorganisms are transmitted from one organism to another.
The chain of infection starts with the agent of infection that is the one which makes people sick. It exists in a reservoir, where the agent of infection lives. There is a portal of exit. It is the way the agent leaves the reservoir. Then we have the mode of transition. It could indirect or direct contact with the agent. The agent o infection enters a new body through what is known as a portal on entry. Finally, the host. It is the individual who receives this agent and gets sick.
