BIO1100 ACTUAL EXAM SCRIPT 2026
COMPLETE QUESTIONS AND ANSWERS
GRADED A+
◉ Science: Answer: Knowledge that covers general truths or the
operation of general laws, especially when acquired and tested by
the scientific method (knowledge about the natural world).
◉ Hypothesis: Answer: A suggested explanation for an event, which
can be tested.
◉ Scientific Theory: Answer: A generally accepted, thoroughly
tested, and confirmed explanation for a set of observations or
phenomena.
◉ Scientific Laws: Answer: Describe how elements of nature will
behave under certain specific conditions, often expressed in
mathematical formula.
◉ Control: Answer: The component in an experiment that is not
affected by
changes occurring from the independent variable. The
component used for comparisons.
,◉ Independent Variable: Answer: The component that varies or is
manipulated by the researcher (what we expect will influence
dependent variables).
◉ Dependent Variable: Answer: The response or results that is
measured (happens as a result of the independent variable).
◉ Basic Science: Answer: AKA "pure" science seeks to expand
knowledge regardless of the short-term application of that
knowledge.
◉ Applied Science: Answer: Aims to use science to solve immediate
problems (problems as defined by the researcher).
◉ Homeostasis: Answer: Maintaining internal balance.
◉ Evolution: Answer: The process of gradual change during which
new species arise from older species.
◉ Know the steps of the scientific method and understand the
process: Answer: A method of research with defined steps that
include
,experiments and careful observations (a guideline and can be
altered to fit many different research projects).
1.) Make an observation
2.) Ask a question
3.) Form a hypothesis
4.) Make a prediction
5.) Create and perform an experiment
6.) Collect and analyze data & results
7.) Report the results
◉ Step 1: Make an observation Answer: Observe something of
interest.
Example: You observe your neighbor's garden is full of healthy,
beautiful plants.
◉ Step 2: Ask a question Answer: Question something about what
you observed.
Example: You wonder what your neighbor does to make them so
healthy, you ask him and he says he uses a phosphate-based
fertilizer.
, ◉ Step 3: Form a hypothesis Answer: Formulate a possible answer
to the question (a hypothesis must be testable. it should also be
falsifiable, meaning
that it can be disproven by experimental results. a hypothesis can be
disproven, or eliminated, but it can never be proven).
Example: You hypothesize that phosphate makes plants grow big
and healthy.
◉ Step 4: Make a prediction Answer: Make a prediction based on
your hypothesis.
Example: You predict If you add phosphate to your plants, then they
will grow bigger and healthier.
◉ Step 5: Create and perform an experiment Answer: Create an
experiment to test your hypothesis (an experiment has
requirements: it can have only 1 variable. everything except the
variable must be exactly the same. it must contain a control group
and an experimental group).
Example: Control flower with no phosphate and 3 other flowers with
varying amounts of phosphate added and everything else (water,
sun, etc) stays the same.
