1. DNA is not able to undergo transcription as well as translation. As a result, the genes are unable to be expressed.

2. Water

2.1. High heat of vaporization

2.1.1. Change from liquid to gas

2.1.2. Without this property all the water in our cells would evaporate

2.1.3. The amount of energy needed to change 1 gram of substance into a gas at a constant temp

2.1.4. high humidity on a hot day prevents evaporation

2.2. Cohesion

2.2.1. The H bonds in water are strong and allow for a high water surface tension

2.3. High density

2.3.1. Water is denser as a liquid

2.4. High boiling point

2.4.1. The waters hydrogen bonds need a lot of energy to break

2.5. High specific heat

2.5.1. Can absorb a lot of energy before the bonds break due to H bonds

2.5.2. This is how oceans regulate heat

2.6. Adhesion

2.6.1. Water attaches itself to polar molecules over itself this allows capillary action (water going up the plant) to occur when paired with the high cohesion properties

2.7. Hydration shells

2.7.1. Water molecules come between the two atoms of a molecule and separate it

2.8. universal solvent

2.8.1. uses hydration shell to do so

2.9. expansion upon freezing

3. the response that the signal molecule produces is important because it is what allows DNA to replicate and genes to be expressed.

3.1. genes turned on

3.1.1. allows for DNA to be replicated, increases transcription and transltion factors which lead to cell growth and an overall higher metabolism

3.2. genes turned off

4. Chemistry

4.1. Bonds

4.1.1. Intermolecular forces Hydrogen bonds Strong polar bonds between molecules Only involve O, N, and F Dipole dipoles Bond formed through partial charges between molecules Van Der walls Short weak interactions between molecules momentary dipole Ion-ion interactions Bond formed between ions Ion-dipole Bond formed between the partial charge if a dipole and a ion Dipole A partial charge due to the unequal electronegativity

4.1.2. Intramolecular forces Polar Unequal sharing of electrons between atoms with very different electronegativity Non polar sharing of electrons between atoms with equal electronegativity

4.3. Base

4.3.1. Substance reduces the H+ concentration of a solution

4.4. Types of isomers

4.4.1. Structural Different arrangements of their atoms have the same atoms

4.4.2. Geometry Same covalent arrangements but different in spacial arrangements Cis isomer Trans isomer

4.4.3. Enantiomers mirror images of eachother none of the 4 can have the same molecule

Ion channel receptor a signal molecule (ligand) attaches itself to a Ion channel receptor, which opens the gate and allows for ions to pass through and triggering a cell response.
