Mastering Biology: Chapter 1 Pre-Test
What is the correct order of the hierarchy of biological organization from the least to the
most complex? - Answer -molecule, organelle, cell, tissue, organ, organ system,
organism, population, community, ecosystem
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.
Chemical nutrients - Answer -Recycle within the ecosystem, being constantly reused.
Prokaryotic and Eukaryotic cells - Answer -use DNA as the information storage
molecule.
How does DNA encode information? - Answer -in the sequence of nucleotides.
Which taxonomic domain includes multicellular photosynthetic organisms? - Answer -
Eukarya (plants and certain algae are photosynthetic organisms)
Competition is central to the theory of natural selection. Why does competition occur? -
Answer -Organisms typically produce too many offspring, and resources are limited.
In order for a hypothesis to be able to be used in science, which of the following must
be true? - Answer -It is testable and falsifiable.
Which of the following is an example of "unity in diversity"? - Answer -a. the structure of
DNA is the same is all organisms.
b. all organisms, including prokaryotes and eukaryotes, use essentially the same
genetic code.
b. the forelimbs of all mammals have the same basic structure, modified for different
environments.
Scientific theory - Answer -Generates testable hypotheses, is supported by a large body
of evidence, and is broad in scope.
