Practice Questions & Answers
commensal relationship - ---✔✔✔ANSWER----form of a symbiotic
relationship, two organisms live in close association with each other. One benefits
while the other is neither harms or benefites. +/0 relationship
polysome - ---✔✔✔ANSWER----cluster of ribosomes
notochord - ---✔✔✔ANSWER----a semi-rigid rod in the dorsal part of all
chordates, this remains as a semi-rigid chord, although in highrt chordates it is seen
only in the embryo and as a vestigial organ.
-a flexible material made out of similar material to cartilage. If a species has
notochord it is by definition it is a chordate. Ex: fish, birds, mammals
enzymes - ---✔✔✔ANSWER----proteins, typically work best at pH7.2
electron transport chain - ---✔✔✔ANSWER----directly produces the pH
gradient by pumping protons out of the mitochondrial matrix. the proton gradient is
used to make ATP.
,closed circuit - ---✔✔✔ANSWER----has continuity and allows current to
flow in it
as you go from left to right across a period, what happens to electrons - ---
✔✔✔ANSWER----electrons are added one at a time, the electrons of the
outermost shell experience an increasing amount of nuclear attraction becoming
closer and more tightly bound to the nucleus.
voltage drop - ---✔✔✔ANSWER----happens as current passes through a
resistance, represents an energy loss, this energy is usually dissipated in the form of
heat.
what temperature does water at sea level boil - ---✔✔✔ANSWER----212F,
100C, 373K
logy - ---✔✔✔ANSWER----lethargic, lacking in energy or vitality, mental
and physical slowness
gametes - ---✔✔✔ANSWER----sex cells (sperm and egg), humans have 23
chromosomes in each sex cell (made of 22 autosomes), 1n, haploid because they
have half as many as regular human cells. In a regular cell (not sex cell) there is a
total of 46 chromosomes in each cell or a set of 23.
,regular cells - ---✔✔✔ANSWER----2n, or diploid a set of 23 chromosomes
or 46 chromosomes
sexual reproduction simplified - ---✔✔✔ANSWER----a sperm which is
haploid (n) with 23 chromosomes combines with an egg which is also haploid (n)
with 23 chromosomes to form a zygote (2n) which creates 46 chromosomes or
diploid then it forms an embryo which turns into a fetus.
autosomes - ---✔✔✔ANSWER----In a diploid or 2n human cell there are 46
chromosomes. 2 sex cells (one from mom, one from dad) join with 44 autosomes
(23 from mom 23 from dad). Mom and dad have identical cells called autosomes.
*These are essentially chromosomes that both mom and dad posess that are not
determinants of the zygotes gender (the sex cells do this).
Mom has 22 autosomes, and dad has 22 that each will donate.
In addition to the 22 chromsomes that mom and dad will both donate, 1 more
chromosome has to be added to make 23 chromosomes in total This is the sex
chromsome which determines the sex of the baby. These sex cells are not identical
like autosomes because there is either an X chromsome or a Y chromsome that can
be donated. Mom can donate only an X chromosome. Dad can donate either an X
or a Y chromosome.
sporophytes and how they reproduce simplified - ---✔✔✔ANSWER----
sporophyte is just another name for a plant. some sporophytes produce oversized
ovaries which presents itself as a fruit. There is a remains of a flower on one end of
it. If you cut into the ovary there are fertilized ovules or seeds. Inside of the seed is
an embryo or fertilized egg. When we plant a seed we should be able to grow a
, sporophyte through mitosis. Many sporophytes produce a flower which is diploid
(2n). Through meiosis sporophytes (2n) produce spores which are haploid (n). One
cell in the sporangia undergoes meiosis. At the end we get 4 haploid cells or two
diploid cells. A bunch of haploid cells create a gametophyte. Some of these
gametophytes differentiate into gametes. When a grain of pollen reaches the
entrance of an ovary, it releases the sperm that fertilizes the egg and creates a
zygote or egg. The zygote/egg develops by mitosis into an embyro within an
ovule/seed which is inside of an ovary that starts the process all over again.
genotype - ---✔✔✔ANSWER----determines genetic code (female: XX.
male XY) the father is the one that determines what the sex of the child will be
because the mom can only donate an X chromosome.
terse - ---✔✔✔ANSWER----short, abrubt
fawn (v.) - ---✔✔✔ANSWER----act in a servile manner, attempt to please
jeer - ---✔✔✔ANSWER----taunt, ridicule
query - ---✔✔✔ANSWER----question
disinterested - ---✔✔✔ANSWER----impartial, unbiased
pathetic - ---✔✔✔ANSWER----sad
