BIO 101 LAB MIDTERM UNC ACTUAL
EXAM PAPER 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ Beaker.
Answer: Identify the piece of lab equipment.
◍ Lab Report- Introduction.
Answer: Identify the topic, give background context, and state the
hypothesis. It should briefly review background information, summarize any
prior observations, and explain why the experiment was designed a certain
way. The goal is to lead the reader to the hypothesis, clearly connecting the
independent variable to the dependent variable.
◍ Lab Report- Materials and Methods.
Answer: Should clearly explain how the experiment was conducted in
enough detail for someone else to replicate it. Describe your procedures,
including how and how often samples were collected, number of trials, and
any controls used. Do this without just listing materials; paragraph format.
AVOID: tables, charts, and figures in this section.
◍ Graduated cylinder.
Answer: Identify the piece of lab equipment.
◍ Triple beam balance.
Answer: Identify the piece of lab equipment.
◍ Flask.
Answer: Identify the piece of lab equipment.
◍ Lab Report- Results.
Answer: Should clearly and objectively present your experimental findings.
, Summarize the key data and describe overall trends or patterns without
repeating detailed numbers already shown in tables or figures. Reference
these visuals directly in your text and include any important results not
shows in them. Focus only on reporting what you found- do not interpret the
results or discuss whether they support your hypothesis.
◍ Lab Report- Discussion.
Answer: Interprets and explains your results in relation to your hypothesis
and the process studied. It should address whether your data supports your
hypothesis, what the results mean, how the control helps interpretation, and
how your findings compare to existing knowledge. Avoid broad
conclusions, and focus on relevant strengths and weaknesses rather than
vague claims like "human error." End with a properly formatted list of
references for any cited material.
◍ Pipette pump.
Answer: Identify the piece of lab equipment.
◍ Lab Report- Appendix.
Answer: All Tables and Figures should be numbered, titled, and placed in an
Appendix. Titles must clearly describe what is shown, and symbols should
be explained. Design Tables and Figures to present results clearly and
efficiently, showing the relationship between the independent and dependent
variables. Avoid vague labels like "Trial 1" and use descriptive treatment
names. If multiple trials are done, present the final one to summarize results
for interpretation in the Discussion.
◍ Pipette.
Answer: Identify the piece of lab equipment.
◍ Transfer pipette.
Answer: Identify the piece of lab equipment.
◍ Volvox.
Answer: Kingdom: ProtistaPhylum: ChlorophytaEukaryoteOuter cells

of the cellLower end of oral groove is cytopharynx- forms food vacuole
Becomes Anal poreContractile vacuoles- remove excess fluidTwo types of
nuclei: macronucleus and micronucleusConjugation: two cells exchange
micronuclei and thus genetic material
◍ Euglena.
Answer: Kingdom: ProtistaPhylum: EuglenophytaUnicellularPhotosynthetic
and contains chlorophyllPhagocytosis- posses the ability to surround and
ingest food particlesMove using flagella
◍ Amoeba.
Answer: Kingdom: Protista Phylum: Amoebazoa UnicellularHeterotrophic
Uses pseudopods to move and feed
◍ Hot plate.
Answer: Identify the piece of lab equipment.
◍ Test tube clamp.
Answer: Identify the piece of lab equipment.
◍ Test tube rack.
Answer: Identify the piece of lab equipment.
◍ Human epithelial cells.
Answer: Kingdom: AnimaliaPhylum: ChordataHumans are multicellular,
these are individual cellsFeature prominent nuclei, particularly when stained
◍ Elodea.
Answer: Kingdom: PlantPhylum: MagnoliaphytaCell wall and
chloroplastsNucleus may or may not be visible Experience plasmolysis
