Please help me this due at 8:00( 25pts) 1: molecules have unequal sharing of electrons among atoms

2: Proteins in the membrane act as enzymes? which allows molecules that may have difficulty crossing to the membrane to cross easily. This process is known as . (Example: glucose) This is still considered passive because it moves from high to concentration.

3: Movement of molecules from low to concentration will take . This type of energy needed is called (also known as ATP). These molecules power and move molecules the concentration gradient.

4: Exocytosis also gets important that the cell has made OUT of the cell. (Example: used for creating a cell wall for plants!)

Explanation:

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
