Passive transport is the movement of materials through the cell membrane without the use of energy.
Answer:
A. Species
Explanation:
Species is the most specific level of classification in taxonomy.
One mnemonic that can be used to remember the order of ranks is:
Dear King Philip Came Over For Good Soup
This stands for domain, kingdom, phylum, class, order, family, genus, species.
And, this is in order of the most broad to the most specific rank.
So, A is the correct answer.

Cell Hypothesis is one of the fundamental standards of science. Credit for the plan of this hypothesis is given to German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.
Cells need nutrition in order to get the required elements. Which specific foods provide specific elements, and what do those elements do in the cell?
...
The major macromolecules are:
carbohydrates and lipids - made of carbon, hydrogen, and water.
proteins - provide nitrogen and sulfur.
nucleic acids - provide phosphate.
The relative shortness of time they have been separated is the most important for explaining why there are equal numbers of snapping shrimp species on either side of the isthmus.
Speciation is the process of forming new species.
There are five main types of speciation:
- Allopatric speciation
- Sympatric speciation
- Peripatric speciation
- Parapatric speciation
- Artificial speciation
Although allopatric speciation is the most common type of speciation, all five types are described in more detail in the following sections.
Allopatric speciation occurs when one population is physically separated by a geographic barrier and slowly evolves into two separate species. With separation into different environments comes different environmental pressures that shape natural selection, the survival of the most fit organisms in the environment. These different environments allow for different traits to be selected.
Over time, the selection can create entirely new species. For example, snapping shrimp are a group of shrimp that were separated by the Isthmus of Panama across the Caribbean Sea. Over time, the selective pressures were so different that the populations of shrimp evolved into different species.
