Answer:
Phosphagen --- 10 to 30 seconds
Anaerobic --- 10 to 120 seconds
Aerobic --- more than 120 seconds
Explanation:
Phosphagen energy system last from 10 to 30 seconds, the anaerobic system provides energy for very hard efforts that lasts from 10 - 120 seconds and aerobic system lasts longer than two minutes in duration. The utilization of all three energy pathways are necessary for the athlete to compete because athlete needs energy in huge amount which can't be fulfilled with the use of one energy pathway so the athlete needs and use all the pathways during exercise.
<em>Chemicals </em>that are not made available for public use but only to be used by licensed pest control operators are classified as: Restricted Use Pesticides (RUP).
Pest can be controlled through several <em>methods</em>, which include:
- Biological method
- Physical Method
- Chemical Method
For <em>chemical method</em>, <em>chemicals </em>are used to control or eliminate pests. The use of these <em>chemicals </em>are regulated for safety purpose.
Thus, there are some certain types of <em>chemicals </em>that is not made available for <em>public use.</em> These type of <em>chemicals </em>can only be used by <em>p</em>est control operators that are licensed. They are called, Restricted Use Pesticides, also known as "RUP".
In United States, Restricted Use Pesticides (RUP) can only be used under strict supervision by licensed pest control operators.
In summary, <em>chemicals </em>that are not made available for public use but only to be used by licensed pest control operators are classified as: Restricted Use Pesticides (RUP).
