In the diagram above, what accounts for the green pea seed in the F2 generation?
The green allele is completely dominant over the yellow allele.
These alleles show incompletely dominance
The green allele is recessive to the yellow allele, so it is only seen in a homozygous recessive organism.
These alleles are codominant
The way that one chromosome aligns at metaphase is independent from the way another chromosome aligns. This idea is explained by
the law of independent assortment
the law of segregation
the central dogma
thermodynamics
Let's say B is the allele for brown hair and b is the allele for blonde hair.
If B is completely dominant over b, and Jorge is heterozygous, what is Jorge's phenotype?
Brown hair
Black hair
Blonde hair
Brown and blonde hair
The two-letter code that describes the genetic traits of an organism is called a-
phenotype
allele
genotype
codon
Why is crossing-over important?
It creates genetic variability and adds to diversity
It ends mitosis 1
It causes cancer
All of the above
The sequence of growth and division of a cell is called
mitosis
cell cycle
cancer
meiosis
Maple Syrup Urine Disease (MSUD) is caused by a recessive allele. The Mennonite community of Lancaster County, Pennsylvania is particularly afflicted by MSUD, with over 1 of 176 individuals affected. If an unaffected woman whose mother had MSUD has a child with a man who is homozygous dominant, what is the probability that their child will have MSUD?
100%
25%
50%
0%
_________ are the building blocks for ______

nucleotides, nucleic acids
nucleic acids, proteins
amino acids, lipids
What type of molecule is this?
protein
nucleic acid
carbohydrate
lipid
What is a chemical bond?
interaction between atoms due to e- sharing
interaction between atoms due to attraction of opposite charges
A & B are true
a source of kinetic energy
Nucleoids are found
outside of cells
in prokaryotic and eukaryotic cells
in prokaryotic cells
in eukaryotic cells
Cilia and flagella are able to move/beat/undulate because of
intermediate filaments
microfilaments
microtubules
plasmodesmata
Osmosis refers to
movement of solute particles from high to low
movement of water from high to low
the opposite of diffusion
a semi-permeable membrane
How do enzymes catalyze reactions?
orient substrates
strain bonds in substrate
create favorable microenvironment (i.e. favorable pH)
all of the above
To reduce photorespiration, C4 and CAM plants have adapted by
creating a 4C molecule that is transported to a bundle sheath cell, where the Calvin cycle can occur
undergoing carbon fixation at night when it is cooler, and the calvin cycle in the day
keeping their stomata open in the heat
A and B are true
In fermentation, pyruvate is not fed into the citric acid cycle. Instead...
Pyruvate is fermented to create alcohol or lactate
Pyruvate is fermented to create acetyl coA
Pyruvate is fermented to create ATP
Pyruvate is fermented to create oxygen
The cellular structure where proteins are made is
the nucleus
the golgi
the ribosome
the rough ER
