Alcohol dehydrogenase (ADH) catalyzes the oxidation of ethanol (CH3CH2OH) to acetaldehyde, which is then fed into pathways to make fatty acids or to be used as a fuel source. The human body can therefore tolerate a certain amount of ethanol. However, the body cannot tolerate methanol (CH3OH). When methanol is ingested, ADH acts on it, breaking it down to formaldehyde, which is toxic to the human body. Emergency medical treatment for methanol poisoning includes intravenous injection of ethanol. Which statement provides the simplest, most likely explanation for how ethanol acts to prevent harm from methanol ingestion? a. Ethanol acts to protect ADH from irreversible denaturation by methanol.
b. Ethanol acts as a competitive inhibitor of methanol to decrease the rate of methanol oxidation by ADH
c. Ethanol acts as an allosteric activator to increase the rate of methanol oxidation by ADH.
d. Ethanol acts to dilute the concentration of methanol in the body.
e. Ethanol acts as an irreversible inhibitor of ADH to shut down its ability to carry out methanol oxidation.

Aneuron is stimulated with an electric pulse. the action potential is detected at a point 3.70 cm down the axon 0.0052 s later. when the action potential is detected 7.20 cm from the point of stimulation, the time required is 0.0063 s. what is the speed of the electric pulse along the axon? (why are two measurements needed instead of only one? )

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
