<h2>Answer to Q1: </h2>
C. the data collected when a hypothesis is tested can support a theory.
<h2>Explanation:
</h2>
In scientific method theory and hypothesis are two major components. A hypothesis is either a suggestion for an observable phenomenon, or a prediction of a possible relation among different phenomena. Whereas a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. So we can say that the data collected when a hypothesis is tested can support a theory.
<h2>Answer to Q2
</h2>
B. released
<h2>Explanation:
</h2>
The word Exo means out or released therefore exorgonic reactions are those reactions in which energy is released. The same reaction which allows energy release is called exothermic reaction and the energy is in the form of heat.
<h2>Answer to Q3. </h2>
A. carbon dioxide + water ->glucose + oxygen
<h2>Explanation:
</h2>
Photosynethesis is the process in which plants make their food in the presence of sunlight. A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
<h2>Answer to Q4.
</h2>
B. the activation energy of the reaction
<h2>Explanation:
</h2>
Enzymes are just like catalysts in an y chemical reaction. We know that catalysts are the chemicals which speeds up the reactions. In the same way enzyme speeds up the reaction and they increase the activation energy of any chemical reaction.
