Answer: option C. HF
Explanation: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. Fluorine is more electronegative than hydrogen so the electrons in the bond are more closely associated with the fluorine atom than with the hydrogen atom.
Answer:
Work = 450 J
Explanation:
Force = 90N
Distance = 5m
Work = ?
The relationship between these quantities is given by the equation:
Work = Force * Distance
Work = 90 * 5
Work = 450 J
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.
