POMARICO WITH COMPLETE
SOLUTIONS
about how many species have been named and identified? - ANSWER-1.8 million
organic molecules - ANSWER-contain skeleton structures of carbon with hydrogen and
oxygen
Hierarchy of Biological Organization - ANSWER-Atoms, Molecules, Macromolecules,
Organelles, Cells, Tissues, Organs, Organ Systems, Organisms, Populations,
Community, Ecosystem, Biomes, Biosphere
hydrocarbons - ANSWER-Compounds composed of only carbon and hydrogen
Emergent Properties - ANSWER-New properties that arise with each step upward in the
hierarchy of life, owing to the arrangement and interactions of parts as complexity
increases.
isomers - ANSWER-Compounds with the same formula but different structures.
Energy - ANSWER-capacity to do work
structural isomers - ANSWER-have different covalent arrangements of their atoms
basic unit of life? - ANSWER-cells
geometric isomers - ANSWER-have the same covalent arrangements but differ in
spatial arrangements
prokaryotic cells - ANSWER-do not have a nucleus or other membrane-bound
organelles
enantiomers - ANSWER-isomers that are mirror images of each other
eukaryotic cells - ANSWER-have a nucleus and other membrane-bound organelles
enantiomers require an - ANSWER-asymmetric carbon
homeostasis - ANSWER-organisms ability to maintain their structure and regulate their
internal environment
, asymmetric carbon - ANSWER-a carbon atom that is attached to four different atoms or
groups of atoms
premise - ANSWER-the division of living organisms into groups
functional groups - ANSWER-hydroxyl, carbonyl, carboxyl, amino, sulfhydryl,
phosphate, methyl
prokaryotic domains - ANSWER-bacteria and archaea
hydroxyl group - ANSWER-A functional group consisting of a hydrogen atom joined to
an oxygen atom by a polar covalent bond. Molecules possessing this group are soluble
in water and are called alcohols.
eukarya - ANSWER-Protista, Fungi, Plantae, Animalia
carbonyl group - ANSWER-a chemical group consisting of a carbon atom linked by a
double bond to an oxygen atom
methods of science - ANSWER-discovery science focused on where, what, when and
hypothesis based science focused on the how and why
aldehyde - ANSWER-An organic molecule with a carbonyl group located at the end of
the carbon skeleton.
principles of science - ANSWER-all events have a natural cause: natural casality
natural causes obey natural laws
natural laws don't change with time or distance
ketone - ANSWER-an organic molecule with a carbonyl group located in the center of
the carbon skeleton
hypothesis based science - ANSWER-the scientific method, make observations, form a
hypothesis, conduct experiments, make conclusions
carboxyl group - ANSWER-A functional group present in organic acids and consisting of
a single carbon atom double-bonded to an oxygen atom and also bonded to a hydroxyl
group.
theory - ANSWER-an explanation of natural events that is based on a large number of
observations and or experiments
carboxylic acids - ANSWER-compounds with carboxyl groups
25 essential elements for life - ANSWER-Oxygen 96%
Nitrogen
