Answer: Confirm the presence of alcohol in an individual.
All of the above
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.
The given statement "wilderness ecosystems are dynamic, complex, and often fragile, and may be impacted by human use and activities occurring both within and outside wilderness boundaries," is true.
Wilderness ecosystems
The wilderness ecosystem is the ecosystem that has been left undisturbed by humans. There are many areas on the planet that are considered wilderness such as the Great Barrier Reef, the Amazon forest, etc. They are rich in both flora and fauna diversity.
In the United States, a total of 42× 
ha is under the protection of the National Wilderness Prevention System. They are the lands devoted to the protection of the natural ecosystem. Such an arrangement had to be made due to human encroachment and various other factors that affect the wilderness ecosystem. The main threats to the wilderness ecosystem are
- Using the land for recreational uses
- Grazing by livestock
- Forest fire
- Pollution
- Global warming
- Invasion of alien species
- The unnatural flow of water due to diversions, dams, impoundments, etc.

Answer:
10 chromosomes
Explanation:
If the plant has 20 chromosomes, its sperm (the pollen) will have 10.
Why?
Because when this sperm (pollen) fertilizes a plant egg (?) they must end up with a total of 20 chromosomes for the plant baby.
Alfred Wallace and Charles Darwin where both the theorists
behind the natural selection mechanism by which animals evolve to adapt in
their environment. Distinctively, Wallace was the co-author of the theory by
which his expeditions made him discover the processes that act on how evolution
occurs which he relayed to Darwin. However, as both peers in the theory of
evolution it seems to have arose that Wallace never became popular on this idea
unlike Darwin.
