The three evidence that support the existence of plants on Antarctica are:
- Climate;
- Pollen;
- Herbivorous animals;
Apart from the plant fossils found on Antarctica, there are few other evidence that suggest that plants existed in the past on the now frozen continent. Some of those evidence for the existence of plants on Antarctica are the pollen found in the rocks and fossils of organisms, the climate records, as well as the herbivorous animals.
The pollen is only released by the plants, thus that is a sure indicator that plants were occupying this part of the world.
The climate records on Antarctica that can be seen in the rock layers, suggest that for most of its existence, Antarctica had a warm and wet climate, which is perfect conditions for the plants to thrive.
The herbivorous animals are feeding themselves on plant material, so since there's fossils of herbivores in Antarctica, it for sure is an evidence that there were plants existing in order for them to feed and be able to live in there.
B
An inorganic mineral is not composed of anything that was once alive
Explanation:
Organic minerals made from life. They mainly make up the biosphere and examples are minerals in plants and animals. Even after the death and decomposition of the living organisms, the minerals from the decomposition are considered organic. Organism matter is mainly made up of carbon and hydrogen.
Inorganic material, on the hand, are not derived from life and include substances like metal elements and inorganic salts.

Answer:
Hormones are the body's chemical messengers. They carry information and instructions from one set of cells to another. The endocrine system influences almost every cell, organ, and function in the body.
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.
