BIO 101 LAB FINAL PAPER 2026 FULL
QUESTIONS AND SOLUTIONS VERIFIED A+
●● subjective observation.
Answer: observer-specific observations, qualitative
●● hypothesis.
Answer: tentative explanation of cause and effect based on underlying
observed phenomena, must be testable
●● independent variable.
Answer: the cause
●● dependent variable.
Answer: the effect
●● control variable.
Answer: all the factors are the same as the test group, except this one
factor being tested is left in its normal, unmanipulated state
●● protocol.
Answer: description of steps in a scientific investigation
, ●● occam's razor.
Answer: if there are several explanations that might fit an observation,
the simplest is most probable and therefore best
●● prokaryotes.
Answer: unicellular organisms that lack membrane-bound organelles,
including a nucleus; most abundant organisms in the world and found in
virtually every known habitat; reproduce mostly asexually
●● eukaryotes.
Answer: cells with true nuclei and membrane-bound organelles
●● domain Bacteria.
Answer: bacteria and cyanobacteria/blue-green algae
●● nitrogen fixation.
Answer: bacteria converts nitrogen into forms that can be used by plants
●● decomposers.
Answer: bacteria break down dead plants and animals, and thereby
return the organic materials to the system to be used by other organisms
