Answer:
Energy added to cold water, E1
E1 = m•Cp•ΔT = 6 x 4.187x(42-20) = 6x4.187x22
Energy lost by hot water, E2:
E2 = X(CpΔT) = X x 4.187 x (75-42) =X x 4.187 x 33
So, since E1 = E2
6x4.187x22 = X x 4.187 x 33
X = 6x22/33 = 4.0kg
So the mass of the hot water added to the 6kg of cold water is 4.0kg

Hello! The answer should be A

I’m assuming this entire thing is cellular respiration. pathway a most likely represents alcoholic fermentation, B represent lactic acidosis fermentation, C probably represents aerobic cellular respiration. Alcoholic fermentation doesn’t occur in humans, it occurs in micro bacteria and yeast. Lactic acidosis fermentation occurs in humans when there is not oxygen. That’s why you breathe so heavily after sprinting. Cellular respiration just happens naturally. Idk if that’s what the question is asking so feel free to comment and if this helped, brain answer?
D. Chemical energy
The plant converts solar energy into food for the plants. doing this would be a chemical reaction. At the end of photosynthesis there would be chemical energy. :)
The answer is A.
You can remember this by thinking that since there was no change in the amino acid sequence, the mutation is silent in the fact that it didn't cause any trouble in the amino acid sequence.
