Praxis. Science Subtest (5005)
Soil erosion - answer a geological process that adds new rock to the surface of the
Earth
lunar cycle - answer new moon, waxing (thin) crescent, first quarter, waxing gibbous, full
moon, waning gibbous, third quarter, waning crescent,
perspiring - answer not a way in which mammals keep themselves warm in winter
all objects would hit the ground at the same time - answer what would happen in a
vacuum if a feather and two stones of different weights were dropped simultaneously
from a height of 10 ft.?
metric ruler - answera laboratory instrument most appropriate to use in determining the
volume of a large block of wood of unknown density
a scientific hypothesis - answerit is a testable proposal that may lead to experimentation
the broadest category in the biological taxonomy - answerSpecies
biological taxonomy - answerKingdom, Phylum, Class, Order, Family, Genus, Species
(Think: "Kids Prefer Cheese Over Fried Green Spinach")
order of planets from the sun - answerMercury, Venus, Earth, Mars, Jupiter, Saturn,
Uranus, Neptune, Pluto (Think: "My Very Easy Method Just Speeds Up Naming
Planets")
earth's layers - answercrust, mantle, outer core, inner core
atom - answermade up of protons (positive charge), neutrons (no charge), and
electrons (negative charge). protons & neutrons are inside the nucleus. electrons are
the smallest particle & they are in the shell's orbit
density - answermass of an object divided by its volume. mass is measured in grams
while volume is measured in liters or milliliters. volume: l x w x thickness then you divide
by mass
chemical change - answerany change that results in the formation of new chemical
substances
homeostasis - answerhow bodies regulate themselves. it is the survival of cells.
organisms & population can maintain it in an environment when they have a steady
, level of births & deaths. describes the survival of organisms in an ecosystem & the
successful survival of cells inside an organism
all of his male offspring - answersome human traits are carried by genes on the Y
chromosome. a man will transmit these traits to _____________.
chlorine compound when added to swimming pools - answerdestroys bacteria through
an oxidation reaction
potato with the nail will cook faster because heat will be conducted into the potato -
answerscenario: 2 campers bake potatoes in a fire. both wrap their potatoes in
aluminum foil. one camper sticks a large nail through her potato. what is likely to
happen after the potatoes are placed in the fire?
renewable energy resource - answernaturally replenished on a human timescale, such
as sunlight, wind, rain, tides, waves, and geothermal heat
nonrenewable energy sources - answerwe rely on energy to provide us with electricity,
hot water & fuel for our cars. most of this energy comes from fossil fuels, such as coal,
oil & natural gas. if we use them all up, we can never get more during our lifetime
a star's evolution - answernebula, star, red giant, red dwarf, white dwarf, supernova,
neutron
further, slower - answerthe _____________ away from the sun a planet is, the
______________ the planet's orbital speed, therefore, the longer it takes the planet to
make one, complete revolution
commensalism - answeran association between 2 organisms in which one benefits and
the other derives neither benefit nor harm
eukaryotic cells - answercontain membrane-bound organelles, including a nucleus. they
can be single-celled or multi-celled such as you, plants, fungi & insects
prokaryotic cells - answerdo not contain a nucleus or any other membrane-bound
organelle. bacteria are an example of these
endoplasmic reticulum - answerorganelle in the cell. functions as a manufacturing &
packaging system.
nucleus - answeracts as the cell brain. helps control eating, movement & reproduction
cytoplasm or cytosol - answerfluid that fills a cell
golgi apparatus - answergathers simple molecules and combines them to make
molecules that are more complex. it then takes those big molecules, packages them in
