C190 - INTRODUCTION TO BIOLOGY WGU - UNIT 1:
MODULES 1 2 & 3 EXAM QUESTIONS AND
ANSWERS
1. Atoms join together and form: - ANS☑☑---molecules
2. Molecules consist of: - ANS☑☑---at least two atoms held together by a
chemical bond
3. Macromolecules are: - ANS☑☑---biologically important molecules AKA
polymers
4. Polymers are made by: - ANS☑☑---combining smaller units called
monomers (simpler macromolecules)
5. Macromolecule example: - ANS☑☑---DNA (built of 4 kinds of monomers
(nucleotides) strung together (polymerized) in a sequence that codes for
structure of proteins and other bio molecules.)
6. Building blocks of a cell: - ANS☑☑---when macromolecules form a
membrane-bound sphere
7. Two main types of cells: - ANS☑☑---prokaryotes and eukaryotes
8. Prokaryote characteristics: - ANS☑☑---small and simple, they do not have
any clearly defined compartments inside of them
, 9. Matter - ANS☑☑---Any substance that has mass and takes up space
10. 2 classes of matter - ANS☑☑---biotic (living/have lived)
abiotic (nonliving/never alive)
11. The basic unit of matter - ANS☑☑---the atom
12. The atom is made up of: - ANS☑☑---a dense nucleus surrounded by
electrons
13. Eukaryote characteristics: - ANS☑☑---include membrane-bound organelles
(can be complex)
14. Organelle characteristics: - ANS☑☑---compartments inside the cell that
contain specific groups of macromolecules and carry out specific cellular
functions (i.e. the nucleus which encloses DNA within the cell)
15. Microorganisms: - ANS☑☑---single-celled life forms
16. Tissues are formed when: - ANS☑☑---similar cells work together to fulfill
the same detailed function
17. Organs are formed when: - ANS☑☑---collections of tissues work together to
carry out a common general function
18. Organ systems are formed when: - ANS☑☑---functionally related organs
work together in a higher level of organization (i.e. the circulatory system)
