magnum
3. what is a Basin Shaped pelvis: the pelvis supports and balances the tor-
so, serving as the body's center of gravity
4. what is Valgus the femurs point toward the knees to shift the center of
angle at the knee gravity more easily
5. what is Non-Op- the toes of the foot are in line to efficiently direct downward
posable big toe force toward the ground.
6. what is alterna- Plants have a life cycle with two distinct stages, the
tion of genera- GAMETOPHYTE stage and the SPOROPHYTE stage.
tion in plants Cycling between theses two is known as alternation of
generations. In the HAPLOID GAMETOPHYTE stage, ga-
metes which are reproductive cells, are produced through
mitosis. The male and female gametes fuse to form a
diploid zygote, which then develops into the sporophyte.
The mature sporophyte produces spores through meiosis
and the spores undergo mitosis to produce the haploid
gametophyte.
7. What is radial can be split into two identical halves by drawing a plan
symmetry through their longitudinal axis in more than one direction
with their mouth forming one end of this axis. ( jellyfish,
anemones, corals, comb jellies, adult sea urchins and
starfish) animals have a top and bottom but not clear left
or right or front or back
8. What is Bilateral : can be divided into two mirrored halves by a sagittal
symmetry plane through their midline, splitting the animal into the
left and right sides. Bilaterally symmetric animals are

loss landscapes or change land - use patterns for develop-

as habitat fragmentation. Habitat fragmentation can limit
the natural range of organisms and create artificial inter-
actions with humans and other orginisms ( deer having to

21. What are inva- are species that are not native to a region are said to
sive species? be nonnative or invasive. Not all nonnative species are
invasive. Invasive species can lead to significant econom-
ic and environmental harm, and many invasive species
have been introduced to an area by human activity.

27. Freshwater Bio- Lakes and rivers comprise less then 2 percent of the

running or standing water. Running water include streams
and rivers

36. What is a chemi- when elements join, their atoms are held together. The
cal bond electrons are the part of the atom that form bonds.
37. What is a ionic : involve one atom losing one or more electrons and
bond another atom gaining the electrons that were lost by the
first atom. When atoms form iconic bonds they lose or
gain electrons to achieve stability.
38. What is covalent they share electrons to achive a full outer shell instead of
bonds gaining or losing electrons. Covalent bonds can be single,
double, or even triple bonds ( involving one, two, or three
electrons)
