Bio WGU Study For OA C190 Questions With Verified
Answers
Speciation- - ANSWER -Speciation is the formation of new biological
lineage as one species splits into two or more species.
speciation event- - ANSWER -When an existing species splits or
branches into two or more new species that evolve independently of
each other.
Species- - ANSWER -A group of organisms whose members can and
will breed with each other to produce fertile offspring.
Steroids- - ANSWER -A type of lipid composed of a common carbon
ring structure. Examples include testosterone and cholesterol.
Sustainable technologies- - ANSWER -Solutions that meet human
economic and social needs while preserving the productivity or
biodiversity of ecosystems over a long period of time.
Symbiosis- - 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- - ANSWER -Protein Synthesis. The process of producing
protein chains (polypeptides) by linking together relatively simple amino
acid monomers.
, synthesis (S)- - ANSWER -This is the second phase of Interphase in the
cell cycle where the DNA undergoes replication in preparation for cell
division.
Telophase- - 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- - 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- - 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- - ANSWER -The DNA strand used by DNA
polymerase or RNA polymerase to attach complementary bases during
DNA replication or RNA transcription.
Transcription- - ANSWER -Reading the DNA and encoding an mRNA
molecule with information to be taken to protein-synthesizing regions of
the cell.
transfer RNA (tRNA)- - ANSWER -The type of RNA, directly
involved in protein synthesis, that transports amino acids to ribosomes to
be incorporated into an emerging protein.
, Translation - ANSWER -- Synthesis of a polypeptide from the
information in an RNA sequence.
trophic level - 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- - 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.
Anaphase- - ANSWER -A stage within the mitosis phase of cell
division (also known as cell reproduction). Anaphase starts when sister
chromatids separate from each other and ends when each set of
separated, sister chromatids arrives at the opposite poles of the cell.
anaphase I- - ANSWER -The third stage of Meiosis I—the two
homologous chromosomes separate and migrate toward opposite poles.
anaphase II- - ANSWER -The third stage in Meiosis II—the
centromeres separate and the sister chromatids (now individual
chromosomes) move toward the opposite poles of the cell.
artificial selection- - ANSWER -Deliberate mating between two
individuals who were selected based on desired traits.
, asexual reproduction - - ANSWER -A type of reproduction where
genetically identical offspring are created from a single parent. This type
of reproduction does not utilize meiosis or gametes. Bacteria and fungi
are examples of organisms that reproduce in this manner.and fungi are
examples of organisms that reproduce in this manner.
Atom- - ANSWER -The basic unit of matter that cannot be further
broken down without losing its unique properties. One atom consists of
a dense nucleus surrounded by a cloud of electrons.
Autosomal- - ANSWER -Describes a trait associated with alleles
located on autosomes (non sex chromosomes).
autosomal chromosome- - ANSWER -A chromosome not involved in
sex determination.
biogeochemical cycle- - ANSWER -The processes that transfer
chemical elements between biotic and abiotic components in an
ecosystem. There are several main cycles: the water cycle, the carbon
cycle, the nitrogen cycle, and the phosphorus cycle.
Biome- - ANSWER -A large naturally occurring community of plants
and animals occupying a major habitat. Examples include tropical forest
and arctic tundra.
Biomes- - ANSWER -A pattern of distribution of ecosystems across the
globe, where similar environmental conditions lead to similar animal
and plant adaptations. Examples of biomes include tropical rainforests,
deserts, and tundra.
