What the Biology?
There are 7 unifying characteristics of life. Name 3 of them. (bonus points if you can name all 7)
What are: Order, Sensitivity or response to the environment, Reproduction, Adaptation, Growth and Development, Regulation, Homeostasis, Energy Processing, Evolutionary Adaptation
What are protons, neutrons, and electrons
Protons: positive charge, determine the number of electrons, half of the weight of the atom
Neutrons: Neutral charge, Nearly identical mass to protons (exception given to Isotopes)
Electrons: Negative charge, determine bonding type/capacity
What makes H2O such an versatile solvent?
The polarity of the molecule
What are the 3 Domains of life
Eukaryote, Bacteria, Archaea
Relative strengths of each type of bond in order from most to least strong
Ionic & Covalent -> Hydrogen -> Van der Waal forces
A molecule with two different affinities;
polar end and a non-polar end
What is Amphipathic (Phospholipids are amphipathic)
Differences between DNA and RNA
RNA has Uracil instead of Thymine
RNA is single stranded
RNA has ribose not dioxyribose
What are the three components of a nucleotide
Glucose, Phosphate group, Nitrogenous base
The type of bonds that occur between water molecules that cause water to adhere to itself
What are Hydrogen bonds
What are the two main secondary structures formed in proteins?
Alpha Helix or Beta Pleated Sheet
What is the name for the monomers that proteins are made from
What are Amino Acids
What is the unified cell theory?
1. All known living things are made up of one or
more cells.
2. All living cells arise from pre-existing cells by
division.
3. The cell is the fundamental unit of structure and
function in all living organisms.
