Answer:
the answer is B. It is very costly to use
Explanation:
Using biomass to produce electricity takes a ton of water, and its not worthwhile because of it.
hope this helps!
Answer:
Water will move out of the cell because the beaker solution has a lower water potential than the cell is the answer.
Thus Option C is correct.
Explanation:
The way how a water moves from one point that is out of the cell to the another point that is into the cell is called as water potential. It depends on two factors, that is, the solute potential and pressure potential. The solute potential has an inverse relationship with the water potential.
If the solute potential is higher than water potential will be less and vice versa. So in this above mentioned experiment the solute potential of the cell is less than that of the solution so water will move out of the beaker as per the rule.

]To calculate the amount of heat entering or leaving a system, the equation
Q
=
m
c
Δ
T
is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.
