What are the main groups of organic molecules that build
cells and their parts? - Answer-Carbohydrates, proteins,
lipids, nucleic acid
What are the properties of water? - Answer-Its attraction to
polar molecules.
High-specific heat.
High heat of vaporization.
The lower density of ice.
High polarity.
Carbohydrates - Answer-Broken down to glucose to
provide energy.
What are the different kinds of carbs? - Answer-Glucose=
monosaccharide that serves as blood sugar
,2|Page
Sucrose= disaccharide which is table sugar
Polysaccharides= include starch, which stores energy in
plants
Glycogen= stores energy in animals
Cellulose= makes up the structure of plant cell walls
Protein - Answer-macromolecule that contains carbon,
hydrogen, oxygen, and nitrogen; needed by the body for
growth and repair
Lipid - Answer-Energy-rich organic compounds, such as
fats, oils, and waxes, that are made of carbon, hydrogen,
and oxygen.
Serve as a long term energy source
Nucleic acid - Answer-macromolecule containing
hydrogen, oxygen, nitrogen, carbon, and phosphorus
Form DNA which acts to store genetic information
What is the cell theory? - Answer-All living organisms are
made up of cells
,3|Page
The cell is the smallest structural and functional unit of all
living organisms
All cells arise from pre-existing cells
Characteristics of living things - Answer--All are composed
of cells
-All obtain energy and use it to develop
-Can sense changes in the environment and adjust in
response to change
-Exhibit modifications that represent adaptations to their
environment
Levels of Biological Organization - Answer-atom,
molecule, organelle, cell, tissue, organ, organ system,
organism
How are organisms classified? - Answer-on the basis of
their evolutionary/genetic relatedness
What is the scientific method? What is it's importance in
biological sciences? - Answer-Process used to validate
observations while minimizing observer bias
, 4|Page
It's goal is for research to be conduced in a fair, unbiased
and repeatable manner. The best way to discover how and
why the world works
What is matter? - Answer-Anything that has mass and
takes up space
What is an atom? - Answer-smallest unit of matter that
retains all the chemical properties of an element. They
combine to form molecules which then form into a solid,
gas or liquid
What is the structure of an atom? - Answer-Nucleus in the
center that contains protons (positively charged) and
neutrons (no charge). The outermost region is called an
electron shell that contain the electrons (negatively
charged)
What is an ionic bond? - Answer-A chemical bond that's
formed when an atom transfers and electron to another
Atom
