has much oxygen

blood coming into the left atrium of the heart

platelets

blood clotting involves

neural plasticity

that fact that your thinking processes may be altered and damage to the brain may be healed is likely contributed to

none of these (red blood cell)

which blood component is directly involved in oxygen transport

something beats nothing

dominant genes are expressed because

allow many possible neural connections

the function of dendrites is to

whole numbers of ratio offspring

mendel deduced 2 things based on

sensory

the cochlea, retina, and tongue possess many ________ neaurons

vascoconstriction

the body may use _______ to increase blood pressure

brain stem

most of your involuntary body functions are controlled by the

TtWw

which is an example of heterozygous for two completely dominant traits

incomplete dominance

LS x SS is an example of complete or incomplete dominance?

2

in LS x SS, how many different gametes can the mother produce

be able to draw a punnet square

be able to draw a punnet square

TATTGCCGTTGG (A goes with T and G goes with C)

what is the coding strand for this dna if the complimentary strand is ATAACGGCAACC

none of these

polymerase chain reaction (PCR) is a way to

spiraling strands of dna

which best describes the way your cells store genetic info

GMO

an E. coli bacterium that has been changed by adding foreign genes might be considered a

transcription

the process of making an mRNA molecule, based on the dna code is called

amino acid

each RNA codon codes for a particular

necleic acid or nucleotide

the basic unit of dna is

codons

the 3 letter words for rna sentences are called

what would the mRNA molecule be if coded by dna strand: GGCCTCTATCG

a code for a protein

a gene would be best described as

has at least 5 mutations

a typical human cancer cell

transcription

rna polymerase is used during

inserting new genes into an organism

bacterial plasmids are used in

colorblindness

which is a sex linked trait

cut dna at a certain place

restriction enzymes

the primary difference between mitosis and meiosis is noted during the first

grow an organism from a single cell whose DNA has been changed

the primary usefulness of cloning is to

"cut" dna is different in each person

dna fingerprinting depends on the principle that

at the ribosomes on the rough ER

translation occurs

introns

the non-coding pieces of mRNA are called

are totipotent

stem cells are useful in that they

early detection, eating antioxidants, avoiding mutagens, not smoking

a good strategy against cancer

it is mostly influenced by environment

when a trait is not very heritable

at the same location on the other paired chromosome

a homologous allele would be

father

who could not ultimately pass a hemophilia gene to a son

substitution

what has happened to the second dna strand

PCR becomes messed up

the offspring of closely related parents often express genetic problems because

essay: in your opinion, which genetic/DNA concept presents the greatest danger to today's society? defend your assertion with proper terminology

co2 and water

the starting reactants of photosynthesis are

light

all bio-energy on earth is ultimately derived from

carbon fixation refers to

none (2)

glycolysis typically produced this many atp-like molecules per glucose molecule

everything except blue-green

which light wavelength would be absorbed and used by a bluegreen-leaf plant

differing H+ concentrations on either side of the membrane

the atp synthase complex is powered by

the citric acid cycle

during aerobic respiration, CO2 is first released just before

none of these (electron transport system)

the oxygen we breathe in is ultimately used in the

calvin cycle

ATP is used to convert CO2 to carbs during

mitochondria

aerobic respiration occurs primarily in

(these are all found in eukaryotic cells) chromoplasts

which would not be found in every eukaryotic cell

G3P (sugar)

in which compound is there a significant amount of stores energy

missing the enzyme that affects fumaric acid
