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 .

Purple stem plants can be formed by genetics, they use their energy slightly different from other plants, they use less energy, but that may also be because of bad nutrition, and because they may be hungry for nutrients.

Explanation:
i=They can keep its body temperature the same no matter what the outside temperature .
ii=They can maintain a constant body temperature.
iii=They obtain energy from food consumption.
iv=They maintain their body temperature higher than environment.
