AP Bio Crash Course - Questions
What's a hydroxyl group? - ✅✅--OH
What's a carbonyl group? - ✅✅--C=O

What's a carboxyl group? - ✅✅--COOH

What is an amino group? - ✅✅--NH2

What is a phosphate group? - ✅✅--PO4

What is a sulfhydryl group? - ✅✅--SH


✅✅
What was Lamarck's proposed mechanism for evolution, and was it correct or
incorrect? - -Inheritance of Acquired Characteristics- if a trait is used, it will
be passed down to the next generation, but, if not used, then it will be discarded
and not passed along.
Incorrect

What was Darwin's mechanism for how change occurs? - ✅✅-Natural selection
What was Charles Lyell's theory? - ✅✅ -Earth has been around for a long
period of time and geological processes like volcanic eruptions that occur
presently also occurred in the past (uniformitarianism) and that these types of
processes, over a long period of time, account for large-scale changes in the
Earth's physical characteristics (gradualism)

What was Thomas Malthus's idea? - ✅✅ -Population size remains fairly steady,
despite its capacity for exponential population growth, because of disease, wars,
and limited resources

What does the Theory of Natural Selection state? - ✅✅
-Reproductive success
of an organism depends on its ability to adapt to the environment in which it
resides
Postulates:

,-If environment can't support the population, there is competition within species
that affects offspring production
-Survival depends on genetic background. Individuals with traits that promote
survival will pass these traits to offspring
-The fittest survives, and changes in the population (genetic variation and
mutations) cause variance and benefit the reproduction of a population
-A genetic variation is an example of adaptation, and these manifest themselves
to provide an advantage in specific conditions (ex: average beak is larger during
dry season and smaller during wet season)

What is population genetics? - ✅✅-The study of genetic variation within a
population of individuals

What is the gene pool? - ✅✅-The total sum of genes within a population at a
given time

What is the Hardy-Weinberg Equilibrium? - ✅✅-The study of the gene pool of a
non-evolving population

What 5 conditions must be met for Hardy Weinberg to work? - ✅✅--Large
population sample
-No migration of individuals into or out of the population
-No mutation
-No natural selection
-Random mating

What is the Hardy-Weinberg equation? - ✅✅ -p² + 2pq + q² = 1
p = frequency of dominant (homozygous) allele (A)
q = frequency of recessive allele (a)
2pq = frequency of dominant (heterozygous) allele (Aa)
Also, the combined gene frequency must be 100% so that p + q = 1

What is microbiology? - ✅✅ -The change in the frequencies of alleles or
genotypes in a population from generation to generation (evolution on a small
scale), which occurs if any of the five conditions of Hardy-Weinberg equilibrium
are not met

, ✅✅
What types of things can happen if the Hardy-Weinberg Equilibrium conditions
are not met? - -Genetic drift
Bottleneck effect
Founder effect
Gene flow
Mutation
Non-random mating
Natural selection


✅✅
What is genetic drift, and which Hardy-Weinberg condition does it break? -
-Changes in the gene pool due to chance because of a small population
Breaks the requirement of a large population sample


✅✅
What is the bottleneck effect, and which Hardy-Weinberg condition does it break?
- -Changes in the gene pool due to some type of disaster or massive
hunting that inhibits a portion of the population of reproducing
Breaks the requirement of the large population sample


✅✅
What is the founder effect, and which Hardy-Weinberg condition does it break? -
-A new colony is formed by a few members of a population, so the smaller
sample size, the less the genetic makeup of the population
Breaks the requirement of the large population sample


✅✅
What is gene flow, and which Hardy-Weinberg condition does it break? -
-Transfer of alleles from one population to another through migration. The
gametes of fertile offspring mix within a population, providing genetic variation
Breaks the requirement of no gene flow


✅✅
What is a mutation, and which Hardy-Weinberg condition does it break? -
-A change in the genetic makeup of an organism at the DNA level
Breaks the requirement of no mutations


✅✅
What is non-random mating, and which Hardy-Weinberg condition does it break?
- -Individuals mating with those in close vicinity
Breaks the requirement of random mating
