BSC 101 Final Exam ACTUAL UPDATED
QUESTIONS AND CORRECT ANSWERS
The Scientific Method False: - CORRECT ANSWERS-Oversimplified
-Implies science is an independent effort and isn't linear
-Forgets creativity, technology, and society
-Ignores scientific evolvement
What is the Scientific Method: - CORRECT ANSWERS-Is linear
-Testing Ideas (experiments)
(1) Observation, (2) question, (3) experiment, (4), Evaluation, and (5) Conclusion
Evidence Supporting Evolutionary Theory: - CORRECT ANSWERS1. Fossil
Ev:(Transitional Form)
2. Morphological Homology: (Tetrapod forearm example) (Vestigial traits)
3. Molecular Homology
4. Distribution of organisms/fossils in time and space
5. Chronology
Scientific Inquiry (4): - CORRECT ANSWERS-Testing Ideas( See if it supports evidence or
not),
-Exploration & Discovery (New tech practical problem, curiosity, personal motivation,
serendipity, and surprising observation.)
-Community Analysis & Feedback
- Benefits & Outcome (If research worked and new treatments)
Prokaryotes: - CORRECT ANSWERSCells that do not contain nuclei (bacteria and archaea).
,Eukarya: - CORRECT ANSWERSThey have a nucleus, have membrane, bound organelles,
and ribosomes making protein by following genetic code. (Chitin = Fungi) (multi-culler
usually)
Evolution Corrections/ Misconceptions: - CORRECT ANSWERSM: Evolution is just a
theory
C: Idea betrays misunderstanding of what theory is and how different it is from no induvial
M: Individuals organisms can evolve
C: Evolution changes based on changes in genetic makeup of population over time.
M: Evolution explains the origin of life
C: Not central focus theory how life changes after origin.
M: Organisms evolve on purpose or if they are smart enough
C: Natural selection and process does not involve effort or wanting mutation and genetic
variation
M: Evolution is controversial among scientist
C: Scientist think best explain for life diversity because of evidence supporting it
M: Other theories should be taught
C: Religious views should not be in science and arguments because of evidence
M: Evolution and religion are incompatible
C: One has to choose science over religion. Natural fennoumons and some religions believe
with science and evolution.
Natural Selection: - CORRECT ANSWERS-The process by which certain traits become
more or less common in a population over time due to their influence on survival and
reproduction and adopting
, -Natural selection can lead to speciation, where one species gives rise to a new and distinctly
different species. It is one of the processes that drives evolution and helps to explain the
diversity of life on Earth.
Mutation: - CORRECT ANSWERSRefers to the spontaneous changes in the DNA sequence
that can introduce new genetic variations into a population.
Speciation: - CORRECT ANSWERSIs the process by which one species splits into two or
more species. It occurs when a group within a species separates from other members of its
species and develops its own unique characteristics.
Dominant Alleles: - CORRECT ANSWERSA dominant allele is a version of a gene that
masks the expression of another allele when both are present. The dominant allele's trait will
always appear in the organism.
Ex: G
Recessive Alleles: - CORRECT ANSWERSA type of allele that when present on its own will
not affect the individual. Two copies of the allele need to be present for the phenotype to be
expressed.
Ex: g
Reading Phylogenetic Trees - CORRECT ANSWERSDon't read from the tips first, always
read from the nodes (the point where a group splits into a new group)
Doing a Punnett Square: - CORRECT ANSWERSStep #1 - Create a key showing traits as.
Step # 2 - Make a list of possible allele combinations. & the phenotypes that each would. ...
Step # 3 - Identify the parents that are being used in. ...
Step # 4 - Draw a Punnett square to determine. ...
Step # 5 - Identify the Genotypic ratio.
Step # 6 - Identify the Phenotypic ratio.
How a cell can have different proteins/structures/functions, even though all cells in a single
individual have all the same genes: - CORRECT ANSWERS-Gene expression cells have the
same DNA
-Express different DNA
