WGU C190 Bio Elaborate Study
Questions with Verified Answers
1. Biology - ANSWER the scientific study of life
2. Characteristics of Life - ANSWER a. Be made of materials organized in a
hierarchical pattern.
b. Use energy and raw materials to survive
c. Sense and respond to changing environments and maintain internal stability,
or homeostasis.
d. Grow, develop, and reproduce.
e. Be part of a population that evolves.
3. The Cell - ANSWER the smallest unit that displays all characteristics of life
4. Matter - ANSWER Any substance that has mass and takes up space. All
matter can be classified as biotic or abiotic.
5. covalent bond - ANSWER A chemical bond that involves sharing a pair of
electrons between atoms in a molecule
6. Meiosis 1 - ANSWER (reduction division) during this stage the number of
chromosomes in the parent cell are divided in half because of homologous
chromosomes are separated.
7. Ecosystem - ANSWER A system that includes all living organisms (biotic
factors) in an area as well as its physical environment (abiotic factors)
functioning together as a unit. Supplement. An ecosystem is made up of
, plants, animals, microorganisms, soil, rocks, minerals, water sources and the
local atmosphere interacting with one another
8. Biosphere - ANSWER The biosphere is the zone of air, land and water
where organisms exist. It is commonly known as the global sum of all
ecosystems
9. Commensalism - ANSWER a relationship between individuals of two
species in which one species obtains food or other benefits from the other
without either harming or benefiting the latter.
10.Predation - ANSWER A of symbiotic relationship between two organisms
of unlike species in which one of them acts as predator that captures and
feeds on the other organism that serves as the prey.
11.Symbiosis - ANSWER Sometimes beneficial, sometimes harmful, these
relationships are essential to many organisms and ecosystems, and they
provide a balance that can only be achieved by working together.
12.Competition - ANSWER An interaction between organisms or species in
which both the organisms or species are harmed
13.Parasitism - ANSWER A non-mutual relationship between species, where
one species, the parasite, benefits at the expense of the other, the host
14.Herbivory - ANSWER When animals eat plants or plant-like organisms,
and a herbivore is a type of animal that eats plants or plant-like organisms
15.Nitrogen Cycle - ANSWER continuous series of natural processes by which
nitrogen passes successively from air to soil to organisms and back to air or
, soil involving principally nitrogen fixation, nitrification, decay, and
denitrification.
16.What is responsible for Nitrogen Fixation? - ANSWER Bacteria
17.Four Phases of Cell Division - ANSWER - G1, cell growth
- S, duplicating DNA
- G2, continues to grow/checks DNA for mistakes
- M, cell divides
18.Acronym for Mitosis - ANSWER I P P M A T C
I nterphase
P rophase
P rometaphase
M etaphase
A naphase
T elophase
C ytokinesis
Interphase (mitosis) - ANSWER - DNA is copied
- centrazomes are replicated
Prophase (mitosis) - ANSWER - DNA condenses
- Mitoic spindle forms
