WITH ANSWERS.
Symbiosis- - correct answer -A type of direct community
interaction between pairs of species that are intimately and
physically connected, with a smaller species (symbiont) living in
or on the body of a larger species (host). These direct interactions
are described using the term symbiosis, which translates to
"together living."
Synthesis- - correct answer -Protein Synthesis. The process of
producing protein chains (polypeptides) by linking together
relatively simple amino acid monomers.
synthesis (S)- - correct answer -This is the second phase of
Interphase in the cell cycle where the DNA undergoes replication
in preparation for cell division.

Telophase- - correct answer -This is the final stage of mitosis. In
telophase, new nuclear envelopes form around the separated
chromosomes at each pole of the cell, the chromosomes unfold
back into chromatin, nucleoli reappear, and the cell continues to
elongate.
telophase I- - correct answer -The final stage of Meiosis I—the
homologous chromosome pairs reach the poles of the cell,
nuclear envelopes form around them, and cytokinesis produces
two separate cells.
telophase II- - correct answer -The final stage of Meiosis II—
nuclear envelope forms around each set of chromosomes and
cytokinesis occurs, producing four daughter cells, each with a
haploid set of chromosomes.
template strand- - correct answer -The DNA strand used by DNA
polymerase or RNA polymerase to attach complementary bases
during DNA replication or RNA transcription.
Transcription- - correct answer -Reading the DNA and encoding
an mRNA molecule with information to be taken to protein-
synthesizing regions of the cell.

transfer RNA (tRNA)- - correct answer -The type of RNA, directly
involved in protein synthesis, that transports amino acids to
ribosomes to be incorporated into an emerging protein.
Translation - correct answer -- Synthesis of a polypeptide from the
information in an RNA sequence.
trophic level - correct answer --Groupings of species in a
community based on their feeding relationships. These food-
based groupings are called trophic levels. Trophic level 1 is
composed of producers that form the base of all ecosystems.
Organisms in level 1 are eaten by organisms in level 2; organisms
in level 2 are eaten by organisms in level 3; organisms in level 3
are eaten by organisms in level 4, and so on.
trophic levels- - correct answer -Any of the sequential stages in a
food chain, occupied by producers at the bottom and in turn by
primary, secondary, and tertiary consumers. Decomposers
(detritivores) are sometimes considered to occupy their own
trophic level.

Vacuole- - correct answer -A type of vesicle containing mostly
water that is found in the cytoplasm of eukaryotic cells. Vacuoles
are specialized mainly for storage. Their membranes do not fuse
with the membranes of other cellular components.
Vesicle- - correct answer -A membranous sac in the cytoplasm of
eukaryotic cells used to isolate and transport materials in a cell.
water cycle- - correct answer -The biogeochemical cycle through
which water moves between the oceans, atmosphere, glaciers,
soil, and fresh water.
Waxes- - correct answer -Nonpolar lipids that form protective
layers on plants and animals. Waxes are the simplest lipids in
nature, consisting of two long hydrocarbon chains linked in the
middle by an ester group.
Adaptation- - correct answer -The adjustment or changes in
behavior, physiology, and structure of an organism to become
more suited to an environment.
