it's been a LONG time since I looked at the specific definitions of these terms, so correct me if I'm wrong here but position in a food chain (never heard it called that in a while, mostly heard the term 'food web') is based on what you consume right? and by definition AUTOtrophs are...

If you know how to deal with them individually, you're going to be fine... remember the law of independent assortment? I think part of the problem is the very strange allelic naming system... the standard is to use the first letter of the dominant trait and for Capital letters to be dominant...

Yes, that was a typo, and yes it was supposed to be homozygous recessive. to answer the latter question: q = frequency of recessive alleles expressed as a percent or decimal. in this case 0.23 therefore, what I mean by the algebraic (p = 1 - q) is exactly that: (p = 1 - 0.23) and yes...

Dispersion forces are the attractions between opposite ends of temporary induced dipoles, Dipole-Dipole forces are the attraction between oppositely charged ends of permanent dipoles, and Hydrogen bonds are the unusually strong diploe-diploe forces in hydrogen compounds of Flourine, Oxygen, and...

Take a look at the Gibbs Free Energy Equation: ΔG = ΔH - TΔS(init) whereas T is the temperature (SI Units: kelvins); S is the entropy (SI Units: joules per kelvin); H is the enthalpy (SI Units: joules) and remember that when ΔG < 0 the reaction is spontaneous...

Yeah, chemistree is right, I went back and re-read the definitions, The equivalence point definition from my student's textbook was (GASP) wrong! From my own (old and dusty) textbooks the equivalence point is better defined as the point where the acid or base being titrated is completely...

No, it doesn't matter. When the H3O ion concentration is equal to the OH ion concentration, you are at pH 7

remember, H is enthalpy (amount of heat in the system) and S is entropy (amount of disorder in the system). The first one: This reaction is ENDOTHERMIC. It is absorbing heat from its surroundings, which results in a decrease in temperature. (think of it like sucking out the heat, so it gets...

Symbolipoint, be careful, endpoint and equivalence point are not the same. End point is the point at which the indicator changes color (which would vary depending on what indicator you are using) equivalence point is the point at which the unknown acid or base is completely neutralized, this is...

Yeah, like pixel said, it's because of energy in the bonds. There is either less energy required or more energy released (I didn't look it up to find out which) in the process of breaking bonds with water's H+ ion and forming NH4 than there is for NH3 to break a bond with an H+ and form H3O...

two major important equations for Hardy-Weinberg: p + q = 1 and p^2 + 2pq + q^2 = 1 You know 'p' in your problem: it is .73 Therefore you must know that 'q' is .27 since you know p = .73 and q = .27 you can find 2pq (which is the heterozygote frequency) {Moderator edit: remainder of solution...

Yeah, this is all hardy-weinberg stuff, (which requires the utopia of hardy-weinberg equilibrium) Astronuc's lettering style is a bit unconventional but essentially correct. Usually p is the alleleic frequency of the dominant allele and q is the frequency of the recessive. Since it takes two...

Technically speaking, water is amphiprotic. Wiki has a good explination of this: http://en.wikipedia.org/wiki/Amphiprotic But as to the original question: When you combine water with say, Hydrogen Chloride, HCl is the acid and Water is the base (according to Brønsted-Lowry theory becuase...

Chemistree is correct, that there is no practical way to react a sizeable quantity of Francium with Chlorine. Theoretically Francium SHOULD produce a more 'violent' reaction, as most texts I've seen state that "the lowest 1st ionization energy in the alkali metals is Francium". However, every...

well, yes, Bismuth subsalicylate is C7H5BiO4, but the problem is, there are ALOT of other ingredients in Pepto bismol (specifically: benzoic acid, flavor, magnesium aluminum silicate, methylcellulose, red 22, red 28, saccharin sodium, salicylic acid, sodium salicylate, sorbic acid, water.) so...
