Unit 1 Review
The data or observation that is described using numbers.
What is... Quantitative
The weak attraction between the positive hydrogen and negative oxygen of two different water molecules.
What is... Hydrogen Bond
An organism that lacks a true nucleus and membrane-bound organelles.
What is...Prokaryote
An organism that obtains energy from non-living sources like sunlight or chemicals.
What is... Autotroph
The result or outcome that you measure in an experiment
What is... Dependent Variable
The testable prediction about what you think will happen in an experiment.
What is... Hypothesis
Provides structure and support for the body. Structure always contains N-C-C.
What is... Protein
Movement of particles from high to low concentration without using energy until evenly spread.
What is...Diffusion.
The organelle where photosynthesis occurs in plants.
What is... Chloroplast
A well-tested explanation for a wide range of observations or results, supported by a lot of evidence.
What is...Scientific Theory
The conclusion or explanation you make based on your observations and what you already know.
What is... Inference
The polar charge of water allows it to dissolve other polar substances.
What is... Versatile Solvent
A lipid bilayer that surrounds the cell, separating the inside of the cell from the environment and controlling what enters and leaves the cell.
What is...Cell Membrane.
A sugar that is made by plants during photosynthesis.
What is... Glucose
Stores and transmit genetic information used to make proteins. Structure is made of phosphate, sugar, and base.
What is... Nucleic Acid
A group in an experiment that does not receive the independent variable; it’s used to compare results.
What is... Control Group
A substance that speeds up the rate of chemical reactions.
What is...Catalyst
The main molecule cells use to store and release energy.
What is... Adenosine Triphosphate (ATP)
The reactants of photosynthesis.
Carbon Dioxide
Water
Sun's Energy
More solute inside the cell; water moves in, and the cell swells.
What is...Hypotonic
The factor that is changed on purpose or tested in an experiment.
What is... Independent variable
The process that occurs when a protein loses the ability to function and is destroyed.
What is... Denature.
A solution with more solute outside the cell; water moves out, and the cell shrinks.
What is...Hypertonic.
The products of Photosynthesis.
Oxygen
Glucose
Contain enzymes that help digest and remove waste materials.
What is.., Lysosome.
