Answer:
Reesa must perform her training within a heart rate range of 140 and 160 bpm.
Explanation:
Reesa, a 20-year-old athlete, must work on her physical exercises taking into account that her heart rate should never exceed 200 bpm, equivalent to her maximum heart rate (MHR).
MHR is an estimate of the maximum work the heart can do without risk of injury or damage.
The formula for calculating MHR is:
<em>MHR = 220 - age
</em>
In the case of Reesa;
<em>MHR = 220 - 20 = 200 bpm.</em>
Since Reesa wants to train at 70 - 80 % of her MHR, it is calculated:
- <em>MHR70 = 200 X 70% = 200 (70/100) = 140 bpm
</em>
- <em>MHR80 = 200 X 80% = 200 (80/100) = 160 bpm </em>
<u>Reesa should adjust her work so that her heart rate stays between 140 and 160 bpm</u>.
Answer: Blast chiller
Explanation:
Vehicles of contamination help micro-organisms move from one place to another and hence can be a route for contamination.
Of the listed options, Blast Chillers are not vehicles of contamination. Blast Chillers are a bit like advanced freezers because they are used to freeze food at a fast rate. This ensures that food does not remain in the "<em>danger zone temperature of contamination</em>" - <em>period between temperature food is cooked at and temperature it cools at</em>".
As a result of this rapid freezing, items inside a blast chiller stand a way smaller chance of being contaminated as the low temperatures hamper bacterial growth.
