Answer:
C. The atmosphere
Explanation:
The atmosphere is chock-full of carbon due to emissions from living organisms, geological processes, and the production of energy by humans. Trees obtain most of their carbon from atmospheric carbon due to its abundance. Also, the sun provides them with the light energy for photosynthesis, while decaying organisms provide ammonia.
Answer:
The correct answer is option e. "that the protein being studied does not contain disulfide bonds in its quaternary structure".
Explanation:
Reducing agents, such as ß-mercaptoethanol (BME) or dithiothritol (DTT), are elements or compounds that break down disulfide bonds. These agents reduce the disulfide bonds and prevent the oxidation of the thiol groups of the cysteine residues that form the disulfide bonds. If one protein that was not treated with a reducing agent have the same electrophoretic behavior than a protein that was treated with a reducing agent in a SDS-PAGE experiment, then the results most likely indicate that the protein being studied does not contain disulfide bonds in its quaternary structure.
Answer:
a) You can think of independent and dependent variables in terms of cause and effect: an independent variable is the variable you think is the cause, while a dependent variable is the effect. In an experiment, you manipulate the independent variable and measure the outcome in the dependent .
b)Explain. A dark brown mouse is more likely to escape predation under a full moon on a dark-colored soil most likely because it is less visible to the eye of the owl
