BIO 1001 COMPLETE LATEST YORKU
BASED MIDTERM 1 ACTUAL SET WITH
QUESTIONS AND CORRECT/VERIFIED
ANSWERS
CELL THEORY - correct answer-✅o All living organisms are composed of one or more cells.
o The cell is the basic unit of structure and organization in organisms.
o Cells arise from pre-existing cells.
THEORY - correct answer-✅o Scientific theories are testable explanations supported by facts gathered
over time
o Not speculative guesses
o Is tested, well-substantiated, unifying explanation for a set of verified, proven factors
o Evidence-based overarching explanations for general class phenomena
o General = many testable hypotheses related to it
o Supported by large body of evidence = tested multiple ways
o Predictive powers = must fit observations not used in formulating the theory
AN EXPLANATION FOR A VERY GENERAL CLASS OF PHENOMENA
Hypothesis - correct answer-✅o To be useful, hypothesis must:
Clearly establish mutually exclusive alternative explanations for a phenomenon.
Generate testable predictions.
o Needs to be able to be tested empirically
o Suggested explanation for an observable phenomenon or reasoned prediction
o Leads to testable predictions
o A proposed explanation for a tightly focused question
null hypothesis - correct answer-✅o There is no statistical significance between the two variables
o "No difference"
o The one that scientists try to disprove
- specifies what we should see when the hypothesis being tested isnt corretct
Alternatie Hypothesis - correct answer-✅o One that states that there is a statistical significance
between the two variables
o The one scientist is trying to prove
o Must be tested independently of the null hypothesis
Controls - correct answer-✅Group that doesn't receive treatment
Importance: used to determine results without treatment and can be statistically use to see if there is a
difference between the control and treatment/experimental group
- checks for factors other than the one bieing tested that may change the experimenters results
Constant Conditions - correct answer-✅Keeping factors/variables the same between experiments
• Ex. temperature
-eliminates alternative explantions for the results
Repeatability of Tests in Scientific Experiments - correct answer-✅Tests must be repeatable so that it
may be tested by multiple sources & proven to be viable
- by repeating tests the amount of noise in the data caused by usual individuals or sircumstances is
reduced
Evidence vs. Proof - correct answer-✅Proof is conclusive, final
, Evidence allows other possibilities
Believe vs Accept - correct answer-✅Acceptance might not believe in it but 'it is what is it', realistic view
point
Believe YOU believe something is true even if it is not prove to be true
Function vs Purpose - correct answer-✅Function what something does/ particular role assigned to
something
Purpose the 'why' behind the function
Pattern Vs Mechanism - correct answer-✅Pattern regularity in the world
• May be man made or an abstract idea
• Repeats in a predictable manner
Mechanism
• system of causally interacting parts and processes that produce one or more effects
• used to explain phenomena
o ex. natural selection is a mechanism of biological evolution
Observational Study vs. Experimental Study - correct answer-✅Observational Study Not manipulating
an independent variable
• Techniques:
• Qualitative methods: e.g. interviews
• Participant observation e.g., journal
Experimental Study Manipulating an independent variable
• BEST ONE Randomized Controlled Trail (RCT) because of control group
Correlation Vs. Causation - correct answer-✅CORRELATION DOES NOT EQUATION CAUSATION lol
Confusion of correlation and causation.
• E.g. "Global warming, earthquakes, hurricanes, and other natural disasters are a direct effect of the
shrinking numbers of pirates since the 1800s."
Prediction - correct answer-✅o What you think is going to happen
o Sometimes based on evidence or facts but not always
o Something that can be measured and that must be correct if a hypothesis is valid
Refute - correct answer-✅o To prove wrong by argument of evidence; can be shown false or erroneous
Pseudoscience - correct answer-✅o FAKE NEWS LMAO
o Collection of beliefs or practices mistakenly regarded as being based on scientific method
o Ex. those big huge yoga balls and increase in stability (false but people believe in it)
Anecdotal evidence - correct answer-✅o evidence in the form of stories that people tell about what has
happened to them
Irreducible complexity (irreducibly complex) - correct answer-✅o Idea that certain biological systems
cannot evolve by successive small modifications to pre-existing functional systems through natural
selection
o Started because this prof (Michael Behe (hehe)) said that evolution could not explain complex
molecular mechanisms
This ideology was based on the FAKE fact that evolution relies on improvement f functions (IT RLLY
DON'T THO LOL)
Intelligent Design - correct answer-✅o The theory that life or the universe cannot have arisen by chance
was designed and created some intelligent entity
Theistic Evolution - correct answer-✅o God-guided evolution are views that regard religious teachings
about God as compatible with modern scientific understanding about biological evolution. Theistic
evolution is not in itself a scientific theory, but a range of views about how the science of general
evolution relates to religious beliefs in contrast to special creation viewsTheory of
