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.
Explanation:
los seres vivos pueden considerarse sistemas abiertos porque cada ser vivo es un sistema complejo constituido por un conjunto de subsistemas que interactúan y funcionan por un objetivo en común, la conservación y la continuidad de la vida.
Cilia and flagella are hair-like projections in a cell that help to move a single cell. Animals and plant cells lack cilia or flagella because they do not have the need to move about.
Bacteria have flagella to help them move.
