Answer:
The vacuoles in fungi help the cell to maintain the biochemical condition of its internal cellular environment by moderating the pH of the cell.
Explanation:
Homeostasis is the maintenance of the cellular internal environment, in term of solute optimum concentration, pH, ions moderation, and water regulation. The influx of toxic ions such as amino acids and phosphates grouped into the fungal vacoule usually regulate the amount of dissociable hydrogen ions that is available outside, but within the cells. This sustains the hydrogen ion concentration within the fungal cell to such a degree that is needed for physiological process in the cell.
POH = 14 - pH
pOH = -log [OH-]

Answer:
167 kJ
Explanation:
Given parameters
Change in enthalpy = 130 kJ (decrease)
Work done = -137 kJ
Change in energy, \delta = ?
From the first law of thermodynamics:
ΔH = ΔE + PΔV,
Where, ΔH= change in enthalpy
ΔE = change in Internal energy
Substituting values into the above formula —
130 kJ = ΔE + -137 kJ
130 kJ = ΔE - 137 kJ
therefore,
ΔE = (130 + 137 ) kJ
ΔE = 167 kJ
Therefore, the change in energy of the gas mixture during the reaction is 167 kJ.
Since the value of energy change Is positive, therefore this Is endothermic reaction
Salt - Na Cl
Sodium(metal) and chloride(nonmetal)
