NUR 101 Biology Midterm Exam5
1. Observation - correct answeract of noticing and describing events or processes in a
careful, orderly way.
2. Inference and Hypothesis - correct answerInference- logical interpretation base on
what scientists already know(can lead to hypothesis)
hypothesis- scientific explanation for a set of observations that can be tested in ways
that support it or reject it
3. Designing Controlled experiments - correct answerTesting a scientific hypothesis
often involves designing an experiment that keeps track of various factors that can
change, or variables. When ever possible, a hypothesis should be tested by an
experiment in which only one variable is changed. All of the other variables should be
kept unchanged, or controlled.
4 biological macromolecules - correct answercarbohydrates (CH2O), lipids, proteins,
nucleic acids
4. Collecting and analyzing data - correct answerScientists make detailed records of
experimental observations, gathering information called data.
5. Drawing Conclusions - correct answerScientists use experimental data as evidence
to support, refute, or revise the hypothesis being testes, and to draw a valid conclusion.
8 characteristics of life - correct answer• Made up of cells
• Based on a universal genetic code
• Obtain and use materials and energy
• Grow and develop
• Reproduce
• Respond to environment
• Maintain a stable internal environment
• Change over time
Abiotic - correct answernon-living
Abiotic things ... biotic things - correct answeraffect
activation energy - correct answerenergy that is needed to get a reaction started
Adaptation - correct answerheritable characteristic that increases an organism's ability
to survive and reproduce in an environment.
Alcohol fermentation - correct answerYeasts and a few other microorganisms use
alcoholic fermentation, which provides ethyl alcohol and carbon dioxide. A summary of
, alcoholic fermentation after Glycolysis is Pyruvic acid + NADH (arrow) Alcohol + CO2 +
NAD(small +)
atoms - correct answerthe basic unit of matter
ATP - correct answerAn important compound that cells use to store and release energy,
also called as adenosine triphosphate.
Autosome - correct answerchromosome that is not a sex chromosome; also called
Autosomal chromosome
Autotrophs - correct answerorganism that is able to capture energy from sunlight or
chemicals and use it to produce its own food from inorganic compounds; also called a
producer
balanced equations for cell respiration - correct answer6O2 + C6H1206 (arrow) 6CO2 +
6H20 + Energy
balanced equations for photosynthesis - correct answer6CO2 + 6H20 (arrow( Light)
C6H1206 + 6O2
biogeochemical cycle - correct answerprocess in which elements, chemical compounds,
and other forms of matter are passed from one organism to another and from one part
of the biosphere to another
biological community - correct answerassemblage of different populations that live
together in a defined area
Biology - correct answerScientific study of life
biome - correct answera group of ecosystems that share similar climates and typical
organisms
biosphere - correct answerpart of Earth in which life exists including land , water, and air
or atmosphere
Biotic - correct answerliving
Cancer - correct answerdisorder in which some of the body's cells lose the ability to
control growth. Cancer cells do not respond to the signals that regulate the growth of
most cells. As a result, the cells divide uncontrollably.
Carbohydrate - correct answerCarbohydrates are sugar polymers. Carbohydrate is
carbon and water. C6H1206 is the same as C1H201 (ratio is 1.2.1). Starch, Cellulose,
and glycogen are polysaccharides which is a type of carbohydrate. Good energy source
and structure.
