BIO 107 EXAM WITH 100% CORRECT
ANSWERS
What is the membrane bound organelle found in plant BUT NOT animals cells?
Function? - Answer-Chloroplast & its function is PHOTOSYNTHESIS which converts
light energy
Differences between Prokaryotic & Eukaryotic cells? - Answer-Prokaryotic cells are
smaller, & have no nucleus or membrane bound organelles
Eukaryotic cells are bigger & more complex & they have nucleus or several membrane
bound organelles
What does it mean to denture a protein? - Answer-To disrupt or change its 3-D shape
which makes it to lose its function. Breaks the weak bonds & causes denature from
changes in temp, or different processes
Which cell existed first? - Answer-Prokaryotic cells existed first.
What is endosymbiosis theory? - Answer-Endosymbiosis theory Is organelles of
eukaryotic cells which are descended from formerly free living prokaryotic, like the
mitochondria & chloroplasts
What are Enzymes? Function? - Answer-proteins that help speed up metabolism, or the
chemical reactions in our bodies
What are monosaccharides? - Answer-simple sugars (glucose, fructose, galactose)
What are disaccharides? - Answer-short chain carbohydrates (sucrose, maltose)
What are polysaccharides? - Answer-complex long chains of carbohydrates (cellulose,
starch, chitin)
What is biology? - Answer-the study of living things/life
What does it mean for an organism to be alive? - Answer-it generally exhibits
characteristics like cellular organization, metabolism, homeostasis, growth and
development, reproduction, response to stimuli, and evolution over time
, How are living things organized? - Answer-in a hierarchical system, from non-living
components like atoms and molecules to the entire living planet, the biosphere.
Main properties of life - Answer-Organization, energy use, maintenance of Internal
Stable State(Homeostasis), reproduction, growth & development, adaptation/evolution
Homeostasis - Answer-the ability of an organism to maintain constant internal
conditions or "steady state"
Science - Answer-body of evidence based process for acquiring knowledge about the
natural world
Why is science is important/major scientific achievements - Answer-germ theory,
genome editing, antibiotics, DNA:molecular structure, sequencing, theory of evolution
by natural selection, vaccines, the internet, etc
Scientific Method - Answer-observation, hypothesis, experimentation, analysis,
conclusion, report OR observation, questions, hypothesis, experiment, interpret results,
conclusion, result
hypothesis - Answer-an informed, logical, & plausible explanation for observations of
the natural world STATMENT
theory - Answer-generalization drawn from robust hypotheses
What is in your experiment - Answer-Independent variable(manipulated variable)
Dependent variable(response to manipulation)
Standardized variable(held constant)
Control group(untreated group)
Treatment group(Manipulated group)
Chemical reactions during metabolism power life would be - Answer-Respiration
Digestion
Photosynthesis
What is matter - Answer-anything that takes up space and has mass
What is an element? - Answer-A pure substance that cannot be broken down by
chemical means into other simpler substances
Chemical element broken down(ex. Oxygen) - Answer-8=atomic number
Oxygen=element
O=symbol
15.9994=Atomic Mass
