What is heritable
when the variation in a phenotype depends on genes
Diploid (2n)
when a cell contains two copies of each chromosome
haploid cell
when a cell contains one copy of each chromosome
why is the polarity of amino acids important when dealing with mutations?
because a mutation changing an amino acid from polar to non-polar or vise-versa can omit the protein's
function. this makes the mutation not beneficial
Is there a redundancy in base pairs of condones and amino acids?
yes, in the third base especially
what is a silent mutation?
A Silent Mutation is a change in a nucleotide of a codon, but no change in the Amino Acid coded for
which doesn't hurt or benefit the protein.
True or False #21: A point mutation in the third position of a codon is more likely to change the structure
of the protein synthesized from the gene.
false
Why did the genetic code evolve?
1|Page
,The genetic code evolved to minimize the effect of each mutation on the phenotype.
True/False: Opposition to irrational numbers was based on evidence that such numbers cannot exist.
False; (No direct evidence for or against irrational numbers was used to oppose the idea. A religious
belief based on faith was used instead.)
True/False: Opposition to irrational numbers stemmed from a worldview involving naturalistic
evolution.
False
what were the ideas of Lamarck
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during
their lifetime—such as greater development of an organ or a part through increased use—could be
transmitted to their offspring.
How does natural selection operate as a mechanism of evolutionary change?
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in
nature, organisms with heritable traits that favor survival and reproduction will tend to leave more
offspring than their peers, causing the traits to increase in frequency over generations.
Apply the idea of natural selection to understand how populations of bacteria become immune to
antibiotics
Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also
be engineered by applying an evolutionary stress on a population
How do you identify controls and variables What is the difference between independent and dependent
variables?
The independent variable is the one the experimenter controls. The dependent variable is the variable
that changes in response to the independent variable. The two variables may be related by cause and
effect. If the independent variable changes, then the dependent variable is affected
What is heritability?
2|Page
,the ability of a trait to be passed down from one generation to the next
What does it mean to say that mutations are random?
For example, exposure to harmful chemicals may increase the mutation rate, but will not cause more
mutations that make the organism resistant to those chemicals
What is Mendelian Genetics?
a theory of genetic inheritance which was developed by Gregor Mendel
what are Dominant and recessive traits
Dominant traits are expressed, recessive traits are hidden (unless there is only recessive traits - tt)
What is sex-linked inheritance?
Inheritance that may result from a mutant gene located on either the X- or Y-chromosome.
What is the Chi-square test?
checks whether a distribution is significantly different than an expected or theoretical distribution
What is RNA replication?
RNA replication is the process by which new copies of genome-length RNAs are made
how do codons work in DNA replication?
one codon (three nucleotides) contains the info for a specific amino acid
What are silent mutations?
have no effect on the amino acid produced by a codon because of redundancy in the genetic code
3|Page
, What are non-silent mutations?
Nonsynonymous mutations change the protein sequences and are frequently subjected to natural
selection
Most organisms share some features like...
Even the most desperate organisms share some features, suggesting that the single, nine random
process generated diversity.
True or False #1: biodiversity on earth will likely decrease in the near future.
True! Fingerprints of human activity, spread of an invasive species, Rapid change and global climate,
habitat destruction, Deforestation
What are the Three World Views?
1. Natural Evolution - Evolution by natural process2. Theistic Evolution - Evolution guided by God3.
Creation - Species created by God
True or False #3: Scientists believe in Evolution even though they currently lack evidence for the theory.
False! Based on know mechanisms: Natural Selection, Mutation, and Genetic Drift
Evolutionary Theory is accepted by biologist because?
Biologists accept evolutionary theory because its predictions match observations.
True or False #4: Extreme temperatures of 2015 are sufficient evidence to conclude that Earth is
warming.
False! Not enough data to show a trend
On a graph consisting of space and time (X/Y) you compare what?
When something varies over space and time, one must compare sufficient samples to quantify effects
accurately.
What does Replicating Observations do?
Increases reliability of pattern.
What does Controling Conditions do?
Isolates effects of certain factors.
What does randomizing subjects do?
Decreases risk of bias from uncontrolled factors.
What is Creationism and Catastrophism?
All species created in six days, Earth is 6,000 years old, species fixed, extinctions from catastrophe.
Leading Biologist/ Paleontologist who championed this science/theory/belief Georges Cuvier (1769-
1832).
