BSC 101 Unit 1 Exam- Wodika questions with
accurate answers
"Blind" observations Ans✓✓✓ the observer doesn't know which
treatment group they are observing
3 bacteria cell shapes Ans✓✓✓ -Spheres
-Vasilis
-Spirilla
A monohybrid cross Ans✓✓✓ - Yy: half of the gametes will contain
each allele
Adaptions by natural selection Ans✓✓✓ - all living things evolve by
adaptation for natural selection
Allele Ans✓✓✓ genes that come in different versions
allele frequencies Ans✓✓✓ the relative abundances of alleles of a given
gene among all individuals of a population (how common or rare the
allele is)
allopatric speciation Ans✓✓✓ The formation of new species in
populations that are geographically isolated from one another.
-populations become separated
-gene flow is interrupted
,-genetic and phenotypic changes accumulate
- reproduction becomes less and less likely, and eventually impossible
analogous structures Ans✓✓✓ similarities among unrelated species that
result from convergent evolution (evolved independently)
-their underlying structures and genes are not similar
Archaea Ans✓✓✓ Domain of unicellular prokaryotes that have cell
walls that do not contain peptidoglycan
Are all genetic variations because of mutation? Ans✓✓✓ Yes
Are evolution and religion incompatible? Ans✓✓✓ No, they do not
have to choose between the two. No contradiction, deal with different
realms, the spirited and the real.
Are hypothesis just guesses? Ans✓✓✓ no, they are reasoned and
informed explanations
Asexual and Sexual reproduction Ans✓✓✓ -DNA containing genes
asexual reproduction Ans✓✓✓ -Process by which a single parent
reproduces by itself
- regenerates
- cloning
, -offspring are genetically identical to parents
Atom Ans✓✓✓ Smallest particle of an element
-most fundamental unit of matter
-atoms form molecules
avoiding bias Ans✓✓✓ -use random selection and assignment
-make sure it won't effect the outcome
Bacteria Ans✓✓✓ single-celled organisms that lack a nucleus;
prokaryotes
biological fitness Ans✓✓✓ a measure of the ability to survive and
reproduce relative to other members of the population
Biological organization smallest to largest Ans✓✓✓ atom, molecule,
cell, tissue, organ, organ system, organism, population, community,
ecosystem, biosphere
biological species (macroevolution) Ans✓✓✓ Species is a group of
populations whose members have the potential to produce fertile
offspring.
-able to produce viable offspring
