Answer:
Four types of molecules important for cell processes:
1. Proteins
2. Carbohydrates
3. Lipids
4. Nucleic Acids
Explanation:
Foremost, Molecules are groups of atoms that bonded and held together by chemical bonds - which form compounds. Cell processes all involve the interaction of molecules and atoms alike. These four groups are absolutely essential for every single organism on Earth. A cell and organism would not be able to live without these vital molecules.

The % mass/mass concentration of solute in the seawater sample is calculated as below
% mass = mass of the solute /mass of the solvent(sea water) x100
mass of the solute =1.295 g
mass of the solvent(sea water_) = 25.895 g
there the % mass = 1.295/25.895 x100 = 5.001 %
Because H2O molecules make Hydrogen bounding and that's the first and strongest bound between molecules of a structure... So they stick together and don't let each other get evaporated...
U need lotsa energy to turn them into Gas shape
Answer:
Antibiotics destroy bacteria
The volume becomes two. You have to use the equation P1 x V1 = P2 x V2
P is pressure and V is volume.
P1 = 50 P2 = 125
V1 = 5 V2 = v (we don't know what it is)
Then set up the equation:
50 times 5 = 125 times v
250 = 125v
the divide both sides by 125 and isolate v
2 = v
Therefore the volume is decreased to 2.
Also, Boyle's Law explains this too: Volume and pressure are inversely related, This means that when one goes up the other goes down (ie when pressure increases volume decreases and vice versa). Becuase the pressure went up from 50 KPa tp 125 KPa the volume had to decrease.
