I notecards fully solved A+ rated
How were the earliest studies of life performed - correct answer ✔✔anatomically
who invented the microscope - correct answer ✔✔van Leeuwenhoek
Impact of Friedrich Wohler - correct answer ✔✔he synthesized urea in the
laboratory, which dispelled the belief that what goes on in cells is not governed by
the rules of the universe.
Friedrich Meisner - correct answer ✔✔discovered DNA, called it nucleon
Erwin Schrodinger - correct answer ✔✔focused attention on the molecular basis
of life with a book titled "What is Life?" in 1930s.
Avery, MacLeod, McCarty - correct answer ✔✔demonstrated DNA was the genetic
material in the 1940s
Watson, Crick, and Franklin - correct answer ✔✔determined the structure of DNA
Central Dogma - correct answer ✔✔DNA to RNA to Protein
, four types of tissues in higher organism - correct answer ✔✔epithelial
nerve
muscle
connective
Amphiphilic compounds - correct answer ✔✔compounds that have parts that are
hydrophilic and parts that are hydrophobic
Soaps in water - correct answer ✔✔they form micelles, which are half-spherical
structures with the hydrophobic tails on the inside. this is how they trap dirts and
oils.
what forms lipid bilayers in water - correct answer ✔✔glycerophospholipids and
sphingolipids.
What is pH - correct answer ✔✔the measure of the proton concentration in a
solution. it is the negative log of the hydrogen ion concentration.
a strong acid - correct answer ✔✔an acid that will completely disassociate in
water
when is a buffer at maximum capacity? - correct answer ✔✔when the
concentration of acid = the concentration of salt.
what is the buffering range - correct answer ✔✔+/- 1 pH unit of the pKa of the
acid
