Oral ingestion or swallowing is the
administration method that takes the longest time for the drug to reach the
brain. When using this method, the drug is swallowed through the mouth, moves to

than it does with other methods of administration such as injecting.
Answer:
C. phylum
Explanation:
According to the Carolus LInnaeus (1707-1778), He identified the system of classification of organisms into seven taxa which includes: Kingdom, Phylum, Class, Order, Family, Genus, species.
Kingdom:
The highest category into which organisms are classified and in which the whole of nature could fit.
Phylum:
A category used in the classification that consists of one or several similar or closely related classes. It is known as PHYLUM in classification of animal species and DIVISION in plant species.
Class:
One or several similar or closely related orders. Similar classes are said to be grouped into PHYLUM.
Order:
One or several similar or closely related families. Similar orders form a
CLASS.
Family:
One or several similar or closely related genera. Similar families are grouped into an ORDER.
Genus (pl. genera):
A number of similar or closely related species. Similar genera are grouped into a FAMILY.
Species:
A group of similar individuals that can breed and produce fertile offspring.
Similar and related species are grouped into a GENUS.
I have encountered this question before, and the given diagram shows no producers. Moreover, it consists of pictures of five organisms, with no relationship being shown between them. Therefore, in order to make the model more accurate, Maria should add B. The sun and arrows to show the flow of energy.
