Medicine and safety regulations at the work place.
To cause the reaction, catalysts use the catalytic cycles, decomposition reactions, and combustion cycles.
<h3>What do you mean by a reaction?</h3>
A reaction refers to the chemical process where substances mutually act and are changed into different substances.
Catalytic cycles refer to the multistep reaction that involves the catalysts. It is considered the main method that describes the major role of catalysts.
Decomposition and combustion cycles are also used by the catalysts.
Therefore, A and B are the correct options.

<span>In terms of matter and resources, the Earth is essentially a closed system, because matter and resources are fixed.
</span>In terms of energy, the Earth is an open system, because there is a balanced transfer of energy. (The energy<span> radiates into the </span>Earth's system<span>, from the Sun and</span><span> then it is radiated back into space from the </span>Earth. The<span> flows of energy are regulated by the </span>Earth's<span> atmosphere and ozone layer.)</span>
Answer:
i think the answer to your question is B
Explanation:
Explanation:
step 1. let called the acute angles inside the triangle <1 and <2.
step 2. <2 +140 = 180 (supplementary angle)
step 3. <2 = 40°
step 4. <1 + <2 + 90 = 180. (interior angles of a triangle = 180°)
step 5. <1 + 40 = 90
step 6. <1 = 50°
