REVISION NOTES AND STRUCTURED BIOLOGY
OVERVIEW GUIDE
◉ Dr keck studies..... Answer: fish
◉ Crossing over usually occurs among_______ Answer: homologous
chromosomes
◉ in the hierarchal classification system we use to organize life, a
genus usually includes a group of _____ Answer: closely related
species
◉ Crossing over can result in a genotype that is ____ compared to the
parental type. Answer: recombinant
◉ Today, new species are only discovered in unpopulated and
unexplored regions of the tropics. (t/f) Answer: false
◉ Speciation is best described as ____. Answer: a process
◉ The biological species concept states that a species is a group of
_____. Answer: interbreeding individuals
,◉ if you wanted to look at the frequencies of alleles in a population
and see if they were changing through time, what concept that we've
talked about would help you? Answer: Hardy- Weinberg equilibrium
◉ If someone said that the increasing nuclear power generation
would increase the number of people that drowned in swimming
pools, they would be treating nuclear power generation as the ___.
Answer: independent variable
◉ the person in 10 above may also be confusing _____ with their
statement. Answer: correlation and causation
◉ the number of alleles for a gene that a diploid individual will have
is _____. Answer: 2
◉ transcription results in the production of _____. Answer: RNA from
DNA
◉ a benefit of asexual reproduction, compared to sexual
reproduction, is much _____. Answer: faster reproduction
◉ the primary biological purpose of DNA is _____. Answer: to provide
code for the phenotype
,◉ point mutations occur at the same rate throughout the entire
genome. (t/f) Answer: false
◉ a gene pool consists of ______. Answer: all the alleles in a
population
◉ the species concept we will be using in this class is broadly
defined as groups of individuals _____. Answer: where offspring
resemble parents
◉ the current extinction rate for species is ____. Answer: much higher
◉ a point mutation changes ____. Answer: the nucleotide in the DNA
sequence.
◉ Can any part of the figure in questions 10 through 11 be
considered science? if so, what? Answer: yes, data/ observation
◉ if an organism has 20,000 protein coding genes, how might it
produce more than 200,000 protein products? Answer: alternative
splicing, gene regulation
, ◉ list two ways phenotypic novelty (variation/ variability)
originates Answer: - point mutation
-environmental factors
◉ there's a lot of faced in the world and dung beetles have envolved
to take advantage of this spectacular resource. Many ding beetles
move portions of dung down into burrows, into nests, or in other
hiding places. all of these activities of moving dung through the
environments can be viewed as an example of which of the five big
ideas/major learning objectives for this class? Answer: flow of
energy and matter
◉ Five major learning objectives and meanings Answer: 1.
evolution-Populations of organisms have changed through time by
both selective and non-selective processes.
2.Structure and Function: All living systems are made of structural
components.
3. Information Flow and Storage: Information and signals are used
within and among organisms to direct their functioning.
4. Transformations of Energy and Matter: All living things acquire,
use, and release matter and energy for cellular / organismal
functioning.
5. Systems: Living systems are interconnected, and interact on
multiple levels.
