the study of genes - correct answers genomics
if the recombination rate is 50% it is very likely that genes are on seperate -
correct answers chromosomes; recombination rate of 100% is impossible
respiration in cells in the absence of oxygen - correct answers fermentation
membrane potential - correct answers electrical charge difference that exists
across a cell membrane
Gibberellins - correct answers stimulate growth in leaves and stems
small openings in the stem that allow oxygen in and carbon dioxide out -
correct answers lenticels
,stomates - correct answers openings in lower epidermis that allow carbon
dioxide into the leaf and water and oxygen out of the leaf
guard cells - correct answers responsible for forming stomates and cuticle is
thin waxy
inquiry that gives the student the question and the results to examine - correct
answers confirmation inquiry
why are yeasts ascomycetes? - correct answers they form asci with
ascospores during sexual reproduction
granulocytes - correct answers neutrophil, basophil, eosinophil
what makes genetically modified organisms different from another organism -
correct answers d n a
base or alkali - correct answers substance that can donate a hydroxide ion
arsenic pollutes what in the body first - correct answers globulin of hemoglobin
then distributes it everywhere
capsules - correct answers thin stalks produced when moss reproduces;
sporophyte stage
receptors for steroid hormones are located in - correct answers plasma
membrane, cytosol and nucleus of target cells
,detritvores - correct answers mites earthworms and snails are this type of
hereotroph
how much energy is lost from one trophic level to the other? - correct answers
90 percent
s phase synthesis phase - correct answers part of the cell cycle which d n a is
replicated; it occurs between g 1 and g 2
cilia - correct answers play an important role in lung defense against
unwanted particles, they are hair like structures
sinoatrial node - correct answers rhythmic contractions of the human heart
darwin said that the mechanisms of evolution was - correct answers natural
selection
species on earth today descended from - correct answers common ancestral
species - darwin
motor neurons are also called - correct answers efferent neurons
intercellular space and cell wall spaces of plant roots are collectively known as
- correct answers the apoplast
IgE - correct answers immunoglobulin responsible for seasonal allergies
, genetic disease that appears early then increases severity with each
generation - correct answers anticipation- it usually happens with mutations in
trinucleotide repeat regions and parent of origin effects
compound microscope max magnification - correct answers 2000X
pyramidines - correct answers cytosine thymine uracil
dynein - correct answers partners with microtubules inside of cilia and
eukaryotic flagella
behavioral ecology - correct answers study of evolutionary and ecological
basis of animal behavior
haploid number of chromosomes for human - correct answers 23 because
humans have somatic cells with 46 chromosomes
labellum - correct answers sponge like comes from the head of a housefly
used to mop up fluids
mercury - correct answers when used for mining gold, its harmful to the
environment
fission - correct answers nuclear energy uses this to generate power
Nuclear power is made via the conversion of the energy released from the
nucleus of an atom, typically nuclear fission. When a relatively large fissile
atomic nucleus (usually uranium-235 or plutonium-239) absorbs a neutron, a
