BIOL 189 FINAL EXAM COMPLETELY
SOLVED!!!
ATP - ANSWER is the energy currency of cells
genetics - ANSWER The study of physical inheritance among living things is
A, T, G, or C - ANSWER The information used to make proteins is encoded by the four
bases
The result of an error in anaphase that failed to separate a pair of sister chromatids
would result in - ANSWER One cell would have an extra chromosome, and one cell
would lack a chromosome
are aligned at the equator of a cell during metaphase - ANSWER Chromosomes
during prophase - ANSWER The chromosomes become visible and the nucleus starts
to break up
during anaphase - ANSWER Sister chromatids are separating from each other
How do daughter cells at the end of mitosis and cytokinesis compare with the parent
cell before DNA replication occurs? - ANSWER The daughter cells have the same
number of chromosomes and the same amount of DNA
an organism that would reproduce by binary fission - ANSWER Bacteria
zygote - ANSWER The fertilization of an egg by a sperm produces a cell called
The products of meiosis - ANSWER four haploid cells
What is the result of recombination (crossing over) during meiosis? - ANSWER It
creates chromosomes that are a new combination of paternal and maternal material
What is the result of independent assortment during meiosis? - ANSWER Genetically
diverse gametes are produced
An autosome - ANSWER is one of the non-sex chromosomes
A human egg - ANSWER contains 22 autosomes and one X chromosome
phenotype - ANSWER is the term for an observable trait of an organism
, Mendel crossed true - ANSWER breeding pea plants and found?- the dominant trait
always appeared in the F1 generation, but it appeared in a 3:1 ratio of dominant to
recessive in the F2 generation
What do hemophilia, Duchenne muscular dystrophy, and red-green color blindness
have in common? - ANSWER They are X-linked
A pedigree is a representation of - ANSWER a genetic family tree
What single attribute determines that a human fetus is male? - ANSWER the presence
of a Y chromosome
If the sequence TCGTA was used as a template in DNA replication, what would be the
sequence of bases on the newly synthesized strand? - ANSWER AGCAT
A population of deer was threatened with overpopulation until cheetahs were imported.
After a couple of years, there were fewer deer, but the average running speed of the
deer had increased. This is an example of: - ANSWER natural selection
The long neck of a giraffe has developed over a long period of time because giraffes
have needed to stretch their necks to reach food high in trees, and that quality has been
passed on through the generations. This view of evolution would correspond with the
ideas of - ANSWER Jean-Baptiste de Lamarck
A population is - ANSWER all the members of a species that live in a defined
geographic region at the same time
What is the difference between microevolution and macroevolution? - ANSWER
Microevolution describes changes within a population over a short period of time,
whereas macroevolution describes larger changes such as the formation of new
species over longer periods of time
Imagine a population of monkeys in South America whose habitat has been reduced to
the point where only 25 monkeys survive. - ANSWER This is an example of population
bottleneck
Shrews have been documented to travel across frozen lakes and establish populations
on previously uninhabited islands thus, the shrews have a limited gene pool. If this
limited gene pool has allele frequencies that are very different from the allele
frequencies found in the original population, then this would be an example of -
ANSWER founder effect
The biological species concept cannot be applied to bacteria because - ANSWER they
do not reproduce sexually
