1.) Its a controlled experiment because both groups A and B get the equal mount of sunlight and water. The manipulated variable would be the fertilizer.
2.) Because a theory must consists of more than experiment before it can actually be considered a theory. It must be performed multiple times.
3.) Because if the growth was on the B spot, the graph would be a bar graph because the growth would still increase by each day.
The answer is B. Remain still.

Explanation:
Answer: c. 1.89 x 10^14 J
Explanation:
By Einstein's equation, we know that:
E = m*c^2
Where m is the mass-consumed in this case:
m = 2.10g
And we must rewrite this in Kg, knowing that:
1kg = 1000g
Then:
m = 2.10g = (2.10/1000) kg = 0.0021 kg
And c is the speed of light:
c = 3*10^8 m/s.
Then the energy will be:
E = 0.0021 kg*(3*10^8 m/s)^2 = 1.89*10^14 Joules.
The correct option is:
c. 1.89 x 10^14J
I’m pretty sure the tempature starts to rise in each sample.
