BIOLOGY 2401 EVALUATION EXAMS UPDATED
QUESTIONS AND ANSWERS SURE A+
✔✔Ionic Bond - ✔✔Transfer of electrons often resulting in ions ( which have a positive
of negative charge)
Ex: NaCl (salt_
✔✔Hydrogen Bond - ✔✔Weak bond between the hydrogen atom of one molecule and
the oxygen, nitrogen, or fluorine atom of another molecule.
✔✔Intramolecular Bond - ✔✔Between atoms within a molecule (Ionic and covalent)
(Within a molecule)
✔✔Intermolecular Bonds - ✔✔Between molecules (hydrogen bonds)
✔✔The pH scale and how to interpret it - ✔✔Ranges from 0 to 14
Below 7 is an acid
Above 7 is a base or alkaline
7 is neutral
✔✔Biological Compounds 1
Carbohydrates - ✔✔Monomers = monosaccharides (Glucose, Fructose.Galactose)
Polymer = Disaccharides, Polysaccharides (starch, and glycogen)
, Main Use = an immediate energy source
✔✔Biological Compounds 2
Lipids - ✔✔Monomer = glycerol and free fatty acids
Polymers = triglycerides, steroids, eicosanoids, phospholipids,prostaglandins
Main use = energy reserve, hormones, insulation, structural component of cell
membrane
✔✔Biological Compounds 3
Proteins - ✔✔Monomer = amino acids
Polymers = polypeptides or proteins
Main use = movement, transport of substances, immunity, support, catalysts for
chemical reactions
✔✔Biological Compounds 4
Nucleic Acids - ✔✔Monomers = nucleotides, made from sugars , a phosphate, and a
nitrogenous base
Polymers = DNA and RNA
Main use = storage of genetic information and protein synthesis
✔✔Matter - ✔✔Anything that occupies space and has mass (weight)
3 Types are : (Solid, Liquid, Gas)
✔✔Element - ✔✔Matter consisting of atoms of the same atomic number
✔✔Organic Compound - ✔✔Compounds that always contain carbon & hydrogen
✔✔Inorganic Compound - ✔✔Compounds that generally do not contain carbon &
hydrogen
✔✔Acidosis - ✔✔results if the pH is below 7.35
✔✔Alkalosis - ✔✔results if the pH is above 7.45
✔✔How much pH does human blood have? - ✔✔7.35 -7.45
✔✔Organelle 1
Nucleus - ✔✔Controls center of cell
Contains DNA
Absent in red blood cells
✔✔Organelle 2
Nucleolus - ✔✔Site of Ribosomes productions
