Designer Experiments
This variable is what the scientist manipulates in an experiment.
What is an independent variable?
This type of bond involves the unequal sharing of electrons between atoms.
What is a polar covalent bond?
This model describes the cell membrane as a flexible phospholipid bilayer with proteins embedded throughout that can move sideways.
What is the fluid mosaic model?
The specific site of the Krebs Cycle.
What is the mitochondria matrix?
This suffix, from the Greek word "lyein" meaning "to loosen," means decomposition, dissolution, breaking down, or separation.
What is -lysis?
In an experiment testing fertilizer on plant growth, this group receives no fertilizer and is used for comparison.
What is a negative control group?
This subatomic particle varies by number between isotopes of the same element.
What are neutrons?
This two-worded term refers to when molecules continue to move across a membrane in both directions at equal rates
What is dynamic equilibrium?
This metabolic process is responsible for the production of bubbles in champagne.
What is alcohol fermentation?
Supported by evidence such as double membranes, circular DNA, and independent replication, this theory describes the evolutionary origin of mitochondria and chloroplasts.
What is the Endosymbiotic Theory?
This type of graph is used to determine whether there is a correlation between two quantitative variables.
What is a scatter plot?
The chemical reaction that connects monomers together to form a polymer.
What is dehydration synthesis?
This describes a solution that contains a lower concentration of solute compared to the cells placed in it.
What is hypotonic?
This is the reduced version of the dinucleotide coenzyme involved in cellular respiration.
What is NADH?
This molecule, also known as a "ribozyme" because it is made up of half RNA and half enzyme, is essential for cellular function.
What is a ribosome?
In an experiment testing whether microorganisms arose spontaneously, Louis Pasteur used this specially shaped piece of glassware to allow air to enter while trapping airborne particles, keeping the broth sterile.
What is an S-shaped flask?
This level of protein structure includes alpha helices and beta sheets.
What is secondary structure?
This organelle is the site of ribosome synthesis.
What is the nucleolus?
Named out of sequence, this protein is the site of an electron excitation event yielding NADPH, despite being discovered after its counterpart.
What is Photosystem I?
This term was adopted into scientific language around the 1870s to describe the central, kernel-like part of the cell that houses its genetic information.
What is -karyo?
This drug was discovered by accident in 1928 when Scottish bacteriologist Sir Alexander Fleming noticed that mold inhibited the growth of Staphylococcus bacteria on a contaminated Petri dish, a breakthrough that earned him a share of the 1945 Nobel Prize.
What is penicillin?
This bond connects nucleic acid monomers together to form polynucleotides.
What is a phosphodiester bond?
This organelle is responsible for producing steroids.
What is the smooth endoplasmic reticulum?
This crucial enzyme is involved in the carbon fixation phase of the Calvin Cycle by attaching atmospheric carbon dioxide to a five-carbon sugar.
What is RuBisCO?
This organelle, named after the Latin word for "eyelash" or "eyelid," was the subject of Dr. Elsa's PhD research.
What are cilia?
