BSC 1010C EXAM I REVIEW (ch. 1-5) QUESTIONS
WITH COMPLETE SOLUTIONS
based on questions 1-3, what do all carbon atoms (and ions)
have in common? Correct Answers the number of protons, in
this case 6 protons
based on the nuclear atom model, what do hydorgen atoms (and
ions) have in common? Correct Answers they all contain 1
proton
Compare discovery science versus hypothesis-based science,
including inductive versus deductive reasoning Correct Answers
Discovery Science:
- focuses on describing nature through careful observation and
data collection. It often involves making detailed observations
and gathering large amounts of data, which can lead to general
conclusions.
This approach uses inductive reasoning, where specific
observations are used to make broader generalizations. For
example, observing numerous instances of a particular bird
species and noting their behaviors to form general conclusions
about the species.
- helps build foundation of knowledge.
Hypothesis-Based Science:
- involves formulating a specific, testable hypothesis and
conducting experiments to test it. This approach uses deductive
reasoning, where a general principle or theory is used to make
predictions about specific cases. For example, if you have a
hypothesis that a certain nutrient affects plant growth, you
,would design an experiment to test this hypothesis and make
predictions based on existing theories.
- tests and refines knowledge through experimentation.
describe a situation where you would want to use a
stereomicroscope as opposed to a compound microscope?
Correct Answers you would want to use a stereomicroscope
when wanting to view larger specimen, a situation where this
would occur is if you were to view a whole flower under the
microscope.
Describe and explain the properties of cohesion, adhesion, and
surface tension. Correct Answers Cohesion:
- is when water molecules stick together, thanks to hydrogen
bonding. It's like a big water molecule group hug! Cohesion
gives water its high surface tension, allowing some insects to
walk on water without sinking.
Adhesion:
- is when water molecules stick to other substances. Think of
water droplets sticking to a window. This happens because water
is attracted to other materials through intermolecular forces.
Surface Tension:
- is like the "skin" on the surface water caused by the cohesive
forces between water molecules. It's why water forms droplets
and can support objects on its surface. Surface tension is what
allows water striders to glide on water without sinking.
cohesion keeps water molecules together, adhesion makes them
stick to other things, and surface tension gives water its unique
, behaviors like forming droplets and supporting small objects on
its surface.
Describe how science is both a process and a body of
knowledge. Correct Answers process:
- science involves the systematic study of the natural world
through observation, experimentation, and analysis to develop
explanations and predictions about phenomena. It's all about
asking questions, forming hypotheses, conducting experiments,
and drawing conclusions based on evidence.
- more inductive reasoning
body of knowledge:
- encompasses facts, principles, theories, and laws derived from
the scientific process. This knowledge is constantly evolving as
new discoveries are made and existing theories are refined or
replaced. So, science is not just about what we known now, but
also about the continuous growth and expansion of our
understanding of the world around us.
Describe how the density of water changes as it cools toward its
freezing point. At what point is water most dense? How does
this affect the behavior of bodies of water through the seasons,
and why is this relevant to living things? Correct Answers as
water cools down, it's like a magic trick happening! Water is
most dense at 4 degrees Celsius, which is a bit unexpected,
right? Most liquids get denser as they cool, but water plays by
its own rules. When water reaches 4 degrees Celsius, it's like a
density party - all the water molecules get cozy and pack
together as tightly as possible.
