AND ANSWERS GUARANTEE A+
✔✔Prokaryotes, known as _________, break down dead and dying organisms and
release vital elements such as carbon, nitrogen, and phosphorous into the environment.
- ✔✔decomposers
✔✔In the Linnaean classification system, the largest and broadest category, which
encompasses all the other taxa, is the ______. - ✔✔domain Explanation: domain can
be eukarya, archea, or bacteria
✔✔Give an example of a specific type of extremophile and describe the type of
environment it would live in. - ✔✔Thermophile; they live in volcanoes
✔✔Name a tertiary consumer - ✔✔carnivores
✔✔Bacteria that cause illness through the production of exotoxins and endotoxins are
considered _______. - ✔✔pathogenic
✔✔________ reproduction gives rise to new offspring from a(n) _______ organism. -
✔✔asexual
single
✔✔describe coeloms - ✔✔fluid filled cavities
✔✔describe acoelomates - ✔✔have no true body cavity but still meets other
classifications requirements to be considered an animal
✔✔describe eucoelomates - ✔✔has a true coelom that surrounds a gut
✔✔describe pseudocoelomates - ✔✔may appear to have a fluid filled cavity but cells
lining the space are not continuous
✔✔By what process do most protists reproduce? State whether this process is sexual
or asexual. - ✔✔binary fission
asexual
✔✔In deuterostome development, a spiral cleavage occurs in the cell mass. - ✔✔false
In deuterostome development, a radical cleavage occurs in the cell mass.
, ✔✔A relationship between two organisms in which only 1 organism benefits while the
other remains unharmed or unaffected is best described as: - ✔✔commensalism
✔✔___________ have a peptidoglycan cell wall and an outer membrane composed of
various biological __________. - ✔✔cyanobacteria
macromolecules
✔✔Explain why a researcher would choose to study a bacterium instead of a human
when researching human disease. - ✔✔simpler organisms that do not pose serious
ethical risks are preferred in biological research
✔✔Organisms found in the Archaea domain are single-celled, microscopic organisms
with a prokaryotic cell structure and reproduce by binary fission. - ✔✔true
✔✔Which of the following cycles is maintained through environmental processes such
as decomposition, plant uptake, and the weathering of rocks? - ✔✔phosphorus
✔✔The thoracic cavity of Eucoelomates houses which organs/structures?
LAST - ✔✔heart and lungs
✔✔Which type of chemical reaction is used to join monomers in order to form
polysaccharides and involves the loss of only water molecules? - ✔✔dehydration
✔✔Describe the difference between anabolism and catabolism - ✔✔anabolism: sum of
all the chemical reactions that REQUIRE energy. forming chemical bonds
catabolism: sum of all the chemical reactions that RELEASE energy. breaking of
chemical bonds
✔✔Compare and contrast aerobic and anerobic respiration. - ✔✔Aerobic Respiration:
requires the consumption of O2, the terminal electron acceptor is oxygen, primary
process used in the human body
Anaerobic Respiration: does not require the consumption of oxygen, oxygen is not the
terminal electron acceptor
✔✔Describe the products of each of the two main phases of glycolysis. - ✔✔-Products
of the investment phase: G3P and DHAP
-Products of the payoff phase: 2 ATP, 2 Pyruvate, 2 NADH
