BIL 150 FINAL PAPER REVIEW GUIDE
WITH VERIFIED ITEMS AND SOLUTION
WALKTHROUGH
●● Enantimonomer
Answer: Chiral monomers that have more than one form but are not
interchnageable
●● Hydrothermal vents created...
Answer: Iron sulfide+ hydrogen sulfide can react and cause electrpmn
trasnfer
●● Miller Urey experiment produced
Answer: HCN+ Formaldehyde
●● Eukarya
Answer: which encompass all life based upon cells with nuclei,
including: plants, animals, fungi, and single celled protists.
●● Archea
Answer: a prokaryotic-like group of single-celled organisms that thrive
in extreme environments
,●● Bacteria
Answer: Single celled without a nuclei
●● What defines the atomic number of an atom?
Answer: The number of protons in its nucleus.
●● What is the genetic code?
Answer: A 3 nucleotide (base) sequence in mRNA copied from DNA
that specifies the sequence of amino acids in cellular proteins.
●● What are the four elements that make up 96% of a cell's mass?
Answer: Carbon (C), Hydrogen (H), Oxygen (O), and Nitrogen (N),
along with Phosphorus (P) and Sulfur (S) being significant.
●● What are the three fundamental parts of cells?
Answer: Permeable membrane, organelles, and the 'Big Four'
biomolecules (nucleic acids, proteins, lipids, carbohydrates).
●● What are the sources of free energy for cells?
Answer: Heterotrophy (oxidation of foods), phototrophy (capture of
light), and lithotrophy (uses inorganic electron sources).
●● What is an ion?
, Answer: An atom or group of atoms that has acquired an electric charge
by gaining or losing one or more electrons.
●● What is a molecule?
Answer: A group of two or more atoms held together by chemical bonds.
●● What are the main types of organic molecules in cells?
Answer: Carbohydrates, proteins, nucleic acids, and lipids.
●● What is a gene?
Answer: A fragment of hereditary information for one protein,
corresponding to one DNA segment.
●● What is the role of hydrogen bonds in water?
Answer: Hydrogen bonds are responsible for the structure of water and
many of its physical and chemical properties.
●● What encloses cells?
Answer: An amphipathic lipoprotein cell membrane.
●● What is the definition of an element?
Answer: A pure substance that contains only one type of atom.
