The amount of oxygen that mixes with the gas stream effects the intensity of the combustion reaction in Bunsen burner. The correct option among all the options that are given in the question is the last option or option "C". The increase in the amount of air mix will result in a flame that has a higher temperature.
1. The answer is "<span>the energy required to start the reaction".
</span>This energy is called as activation energy of the reaction. If the activation
energy is high, reaction is slow. Enzymes help to carry out the reaction by
a new path by reducing the activation energy. But the energy of reactants
and the products remain as same as without enzyme.
2. The answer is "reaction in cells would be too slow to sustain life<span>".
</span>If the activation energy is very high for the reaction, then that reaction will
be very slow and will require more time<span> to complete the reaction. Then survival is
very low. Hence, the roll of enzymes is very important to sustain life.</span>

Answer: 10. Control Group
11. Identify the:
Control Group = Subject A
Independent Variable = The new and original itching powder.
Dependent Variable = The type of itchiness.
Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.
The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.
The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.
