Answer:
The catalyzed reaction will take time of 
.
Explanation:
According to the Arrhenius equation,
The expression used with catalyst and without catalyst is,
where,
= rate of reaction with catalyst
= rate of reaction without catalyst
= activation energy with catalyst = 59.0 kJ/mol = 59000 J/mol
= activation energy without catalyst = 184 kJ/mol = 184000 J/mol
R = gas constant
T = temperature = 
Now put all the given values in this formula, we get:
The reaction enhances by 
when catalyst is present.
Time taken by reaction without catalyzed = 3900 years
Time taken by reaction with catalyzed = x
The catalyzed reaction will take time of .
Answer:
I think they both need water and sun light to stay alive
Explanation: Animals need water so they can have energy and they have extra energy when they are in the sun they have more energy

Answer: A) Inconclusive; you would not know which of the two variables caused the change.
Explanation:
When you set up an experiment, you must make sure that you control the variables such that only one independent variable changes at a time, while all the remainder conditions (the other independent variables) are controlled (fixed).
By observing (measuring) the dependent variable, while only one independent variable changes you can understandhow such independent variable explains (determines) the dependent variable, leading to a conclusion.
Conversely, if two or more independent variables change at a time, then there is no way that you can tell how the output (dependent variable) is related with one or other of the changes of the indipendent variables. You wolud not be able to discriminate (distinguish) the effect of one or other variable, making the experiment inconclusive
