Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the in the exchange of gtp
Artist 52 [7]
RAS is a very important protein that belongs to a class of protein referred to as GTPases and plays a crucial role in switching on pathways that control cell growth, proliferation, apoptosis and differentiation and migration. For RAS to become inactive it must hydrolyze GTP to GDP which slows down the process of cell proliferation. Mutation in one copies of RAS will result to cancer because the mutated copy will permanently attach to GTP and remain in activated form which will lead to uncontrollable cell division and hence development of cancer.

Hydrogen bonds give water which of the following properties? 1. high pH low pH the ability to resist temperature changes 2. the
Furkat [3]

Answer:

3. into ice, which is denser than liquid water.

Explanation:

Water molecules are held together by hydrogen bonds. The bonding is usually between the hydrogen atoms of one water molecules, and oxygen atom of neighboring  water molecules. Structurally,  both oxygen and  hydrogen atoms  pulls the electon towards themselves.Thus both atoms share   electron by covalent bonding.

However, because oxygen  has a strong positively charged nucleus it pulls the electron more to itself than oxygen. Thus oxygen is partially negative and oxygen is partially positive. This interactions take place among  all the oxygen and hydrogen atoms in water molecules. . The unequal charge distributions is called dipole and the attraction between oxygen and hydrogen is called  hydrogen bonding .

The  orientation of hydrogen and oxygen molecules from dipole -dipole  interactions of hydrogen bonding makes the  oxygen and hydrogen atoms in ice to be pushed apart well spaced out in ice, making them less dense than liquid  water  where they were aggregated.  Thus from the question option C is correct.
