metabolism:

deactivates the drug.

converts the drug into a substance that can be used for energy.

creates substances that are more water soluble than the parent drug.

converts ethyl alcohol to acetic acid.

all of the above

a forensic toxicologist must accomplish a number of tasks in order to reach conclusions about the role of a drug in causing a death. which of the following is not one of these tasks?

Determine the role that tolerance may play in a case.

Explanation:

The field sobriety test is a standard field test which is done by the police officer to determine whether the person suspected of impaired driving is intoxicated with drugs or alcohol. This confirms the presence of alcohol in an individual driver.

Metabolism is a process of conversion of complex food particles or drugs or alcohol into water soluble metabolites so that these can be excreted out from the body readily. The metabolism process deactivates the potent drug, it converts the drug into substances which can be used for producing energy for metabolic reactions. The ethyl alcohol is also converted into acetic acid which is less potent metabolite, which can be excreted out from the body.

A forensic toxicologists is a scientists who performs the laboratory based tasks for identify the origin and concentration of drugs. They also determine the conversion of drug into metabolites in the body. Such a scientists have no role in observing and determining the tolerance of drug in a particular case this is the role of forensic psychologists.

there are plastid colour pigment organelle containing a verity of colours

              plastids contain of three organelles 1) chloroplast   (2)   chromoplast   (3)   lecoplast

            the verities of colours are present in chromoplast rather than green so, petals of sun flavour colour is due to chromoplast.
