2026 Questions and Answers
Systems - Correct answer-A set of interconnected components
Open System - Correct answer-Where inputs and outputs can flow freely
throughout the system.
Closed System - Correct answer-Where inputs and outputs are limited in some
way.
Inputs - Correct answer-Something that comes into the system.
Outputs - Correct answer-Something that is produced by the system
Feedback - Correct answer-When a system produces an output that interferes with
the way an input is analyzed
Modeling A System - Correct answer-A way to study and understand the system.
Example of physical model - Correct answer-Structure of a DNA molecule.
Example Of A Conceptual Model - Correct answer-A flowchart

,Mathematical Model - Correct answer-A mathematical model can be used to
predict something
Simulations - Correct answer-Help us visualize Ex. Gizmos
Emergent Property - Correct answer-A characteristic that is not found in the
components part of a system.
Abiotic - Correct answer-A non-living thing.
Biotic - Correct answer-A living thing.
Levels Of Organization - Correct answer-Atom, Molecule, Organelle, Cell, Tissue,
Organ, Organ System, Organism, Population, Community, Ecosystem, Biome,
Biosphere
Characteristics Of Life - Correct answer-Made of one or more cells, Grows and
develops, Has organization, Reproduces, Requires energy, Maintains homeostasis,
Responds to stimuli, Adapts over time.
Homeostasis - Correct answer-Ability of an organism to maintain its internal or
external environment. All organ systems work together to achieve homeostasis.
Feedback Loop - Correct answer-A series of cellular communications between
specific organs to make a response to the perceived environmental change

, Stimulus, Receptor, Integrating Center (decides how to respond), Effector (does the
response), Response (the action that prevents stimulus).
Negative Feedback Loop - Correct answer-When the response inhibits the
stimulus.
Hypothesis - Correct answer-Should be stated as "if-then-because" if (independent
variable - describe how it will change) then the (dependent variable - describe the
effect), because (explain background that supports the rest of the hypothesis)
Independent Variable - Correct answer-That variable that is being changed, the
variable that is being manipulated.
Dependent Variable - Correct answer-The variable that changes as a result of the
independent variable.
Control Group - Correct answer-What your results are compared to.
Constants - Correct answer-Things kept the same throughout the experiment.
C.E.R - Correct answer-First sentence states the claim, the second states the
evidence, third provides reasoning (link connecting the claim to the evidence).
Element - Correct answer-Determined by the number of protons in the nucleus
Compounds - Correct answer-Atoms of different elements bonded together
