pyramid shaped age structure diagram shows Answer: population is growing rapidly
type of leave made up of leaflets Answer: compound leaves
RNA Answer: single stranded, sugar component is ribose
DNA and RNA are both Answer: polynucleotides
the study of genes Answer: genomics
if the recombination rate is 50% it is very likely that genes are on seperate Answer:
chromosomes; recombination rate of 100% is impossible
respiration in cells in the absence of oxygen Answer: fermentation
membrane potential Answer: electrical charge difference that exists across a cell
membrane
Gibberellins Answer: stimulate growth in leaves and stems
small openings in the stem that allow oxygen in and carbon dioxide out Answer:
lenticels
stomates Answer: openings in lower epidermis that allow carbon dioxide into the leaf
and water and oxygen out of the leaf
guard cells Answer: responsible for forming stomates and cuticle is thin waxy
inquiry that gives the student the question and the results to examine Answer:
confirmation inquiry
why are yeasts ascomycetes? Answer: they form asci with ascospores during sexual
reproduction

,arsenic pollutes what in the body first Answer: globulin of hemoglobin then distributes it
everywhere
capsules Answer: thin stalks produced when moss reproduces; sporophyte stage
receptors for steroid hormones are located in Answer: plasma membrane, cytosol and
nucleus of target cells
detritvores Answer: mites earthworms and snails are this type of hereotroph
how much energy is lost from one trophic level to the other? Answer: 90 percent
s phase synthesis phase Answer: part of the cell cycle which d n a is replicated; it
occurs between g 1 and g 2
cilia Answer: play an important role in lung defense against unwanted particles, they
are hair like structures
sinoatrial node Answer: rhythmic contractions of the human heart
darwin said that the mechanisms of evolution was Answer: natural selection
species on earth today descended from Answer: common ancestral species - darwin
motor neurons are also called Answer: efferent neurons
intercellular space and cell wall spaces of plant roots are collectively known as Answer:
the apoplast
IgE Answer: immunoglobulin responsible for seasonal allergies
genetic disease that appears early then increases severity with each generation
Answer: anticipation- it usually happens with mutations in trinucleotide repeat regions
and parent of origin effects
compound microscope max magnification Answer: 2000X
pyramidines Answer: cytosine thymine uracil
dynein Answer: partners with microtubules inside of cilia and eukaryotic flagella
behavioral ecology Answer: study of evolutionary and ecological basis of animal
behavior
haploid number of chromosomes for human Answer: 23 because humans have
somatic cells with 46 chromosomes
labellum Answer: sponge like comes from the head of a housefly used to mop up fluids
mercury Answer: when used for mining gold, its harmful to the environment

, fission Answer: 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 fission of the atom often results.
Fission splits the atom into two or more smaller nuclei with kinetic energy and also
releases gamma radiation and free neutrons. A portion of these neutrons may later be
absorbed by other fissile atoms and create more fissions, which release more neutrons,
setting up a nuclear chain reaction.
reciprocal altruism Answer: possible explanation for altruism that occurs between non
related individuals; 'return the favor'
two genes have same locus Answer: if they occupy the same position on homogenous
chromosomes
photosynthetic protists are Answer: algae
where do lymphocytes originate Answer: bone marrow
adherens junction Answer: anchors cells to each other by attachments between cells
called cadherins
main solute transported by phloem Answer: sucrose
homologies Answer: similar characteristics due to relatedness in regard to evolutionary
theory
little sponges of hydrogen ions Answer: bases
proteins made by free ribosomes are Answer: made to function with the cytosol
anabolism Answer: chemical process that synthesizes body tissue
muscle and nervous tissue are unique to Answer: animals
primary structure of a protein Answer: unique sequence of amino acids in protein
path pollen takes in an angiosperm to reach plants female gametophyte Answer:
stigma style ovary ovule embryo sac
mouth and nose Answer: where chemoreceptors are located
found in sperm cells Answer: flagellum mitochondria nucleus
night length Answer: Night length, not day length, controls flowering and other
responses to photoperiod. Long-day plants cannot flower if the nighttime exceeds the
critical night length (or critical photoperiod). Short-day plants cannot flower if the
nighttime is less than the critical photoperiod.
