CORRECT ANSWERS
The synthesis of urea from ammonium cyanate... - answer helped dispel the vital force
theory
Vital Force Theory - answer disproved by Friedrich Wohler
organic compounds are only formed in living cells
What makes up proteins - answer Amino Acids
What makes up nucletides - answer Nucleic Acids
What is the longest macromolecule - answer DNA
What are the 3 domains - answer Bacteria (PROKARYOTIC)
Archae (PROKARYOTIC)
Eukarya
What is the difference between prkaryotes and eukaryotes - answer the existence of a
well defined nucleus
What does electronegativity produce - answer polar bonds
What dissolves in water - answer ionic compounds and low MW polar compounds
-because of electrostatic attraction of unlike charges
-their ion-dipole (ions) and dipole-dipole interactions (ethanol or acetone)
Van der Waals - answer interaction between non polar molecules = weak
Micelle - answer can be used as a detergent
-polar hydrophilic head
Hydrogen Bonds - answer H with F, O, N
-interaction between dipoles
-non covalent
How many H bonds can water have - answer 4 because of the tetrahedral arrangement
-2 donor and 2 acceptors
, What were the original gases present in Earth's atmosphere - answer NH3, H2S, CO,
CO2, CH4, N2, H2, H2O
RNA - answer catalyzes it's own processing
-the original coding material
double origin theory - answer development of catalysis and coding system came
separately
-combination of the two produced current life
Prokaryotes - answer single celled, have RIBOSOMES
Glyoxysomes - answer only in PLANT cells, catalyzes glyoxylate cycle
