Most biological molecules are made of stable, covalently bound molecules rather than ionic compounds because:
A) Water is slow to evaporate.
B) Water is adhesive and can bind to charged molecules.
C) The high surface tension of water.
D) Ice is less dense than liquid water.
E) Water is a universal solvent.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
