Cellular respiration
What kind of microscope would you use to view a slide containing the bacteria escherichia coli?
Compound microscope
Why was it better to measure transmittance in the photosynthetic activity experiment?
DPIP causes a reaction that goes from blue to colorless
What is the test that can be used to detect proteins that are produced in GM crops?
ELISA
The first offspring produced from a monohybrid cross are called the __________
F1 generation
Websites are always a scholarly peer-reviewed source?
False
In the process of diffusion, molecules always tend to flow up a concentration gradient.
False, molecules flow down a concentration gradient because flowing up requires work and energy
Standard deviation tells you the accuracy of your data.
False. Standard deviation measures the precision of your data. Percent error measures accuracy of your data

What is the thermostable DNA polymerase that performs the polymerization in PCR?
Thermus aquaticus (Taq)
After an enzyme is denatured due to a limiting effect, the enzyme cannot catalyze the reaction anymore.
True
DNA is more resistant than proteins to processing and can be extracted from highly processed foods.
True
Independent variables are usually plotted on the X-axis. Dependent variables are usually plotted on Y-axis.
True
