  239. Communication characteristics of the endocrine system
    Slow, general, long-lasting
  240. Communication characteristics of the nervous system
    Fast, specific, short-lived
  241. Communication characteristics of the paracrine system
    Local mediator hormones only
  242. Diploid number
    Having a pair of each type of chromosome, so that the basic chromosome number is doubled. 46 in humans.
  243. Haploid number
    The haploid number is the number of chromosomes in a gamete of an individual. This is distinct from the monoploid number (x), which is the number of unique chromosomes in a single complete set. Gametes (sperm, and ova) are haploid cells.
  244. Mitosis
  245. Mitosis yields:
    Two genetically identical, diploid daughter cells.
  246. Meiosis
  247. Meiosis yields:
    Four genetically distinct, haploid daughter cells.
  248. Lipid definition
    Any biomolecule soluble in non-polar solvents and insoluble in polar solvents.
  249. Triacylglycerol (triglyceride) structure
  250. Description of basic steroid structure
    All are four-ringed structures.
  251. Definition of amphipathic
    An amphipathic substance is one that is polar at one end of the molecule (hydrophilic) and nonpolar (hydrophobic) at the other.
  252. Alanine (amino acid) structure
  253. Arginine (amino acid) structure

  267. Serine (amino acid) structure
  268. Threonine (amino acid) structure
  269. Tryptophan (amino acid) structure
  270. Tyrosine (amino acid) structure
  271. Valine (amino acid) structure
  272. 1 mol (at STP) = ? L
    22.4 L = 1 mol of gas
  273. (PV=nRT) What is the value of R?
    .0821
  274. pH equivalents
    • 1e-8 = 8pH
    • 1e-6 = 6pH
    • 1e-11 = 11pH
  275. Determining ionic character
    The compound with the greatest difference in electronegativities between the metal and nonmetal has the most ionic character. Electronegativities tend to decrease down a group of the periodic table.
  276. Precession definition
    Precession is the spin of protons, electrons, and neutrons in an atom. For a nonzero precession in the nucleus of an atom, you have to have an uneven number of nucleons.
  277. Determining moles of a substance
    = moles
  278. Determining number of ions
    moles x Avogadro (6.02e23) = # ions
  279. Litmus paper color changes
    • Red Blue in base
    • BlueRed in acid

    No color change either means it is in the opposite solution, or that the solution is neutral.
  280. London dispersion forces (Van der Waals)
    Weak inter and intramolecular forces between non-polar molecules.

    Ex. When The only thing that changes between molecules is their molecular weight, yet a trend developes in boiling points, these forces are responsible.
  281. A pendulum's frequency depends on...
    • Pendulum length.
    • Acceleration of gravity.

    Changing mass has no effect.
  282. Current (I) is equal to...
    Charge (Coulombs) per unit time (seconds).

    Therefore when given current and charge, simply divide current by charge to get frequency of electrons per second.
  283. Autosome definition
    An autosome is a normal chromosome that is not an allosome.

    An allosome is also called a sex chromosome. For example, in humans there are typically 22 pairs of autosomes and one allosome pair.
  284. Nonsense mutation
    A mutation causes a premature stop codon and terminates translation.
  285. Generic definition of a hormone
    Chemical messengers that are secreted by endocrine tissues and are transported by the bloodstream, instead of by ducts, to the target tissues where they alter cellular activity.
  286. Ln of anything less than 1 is...
    A negative number
  287. N/C is equivalent to...
    V/m
  288. Degrees for perfect destructive interference
    180˚
  289. Bacteria and Eukaryotic cells are the same in...
    That they both have a form of the electron transport chain.
  290. ATP Synthase is...
    The cyclical "ogger" protein that produces ATP at the end of the electron transport chain.
  291. A great solvent in O-Chem reactions
    Anything ether
