Answer:
A. Cell
B. Organ
C. Tissue
Explanation:
cell: The smallest unit of life capable of independent reproduction. Generally contains nucleic acid, cytoplasm, a cell membrane, and many other proteins and structures.
organ: A structure made of different tissues that work together to perform physiological functions.
Tissues: A group of similar cells with the same origin that work together to perform the same function.
The second edition of bergey's manual of systemic bacteriology is largely based on of prokaryotic classification.
<h3>What does bergey's manual of systemic bacteriology talk about?</h3>
Since publication of the first edition of Bergey's Manual of Systematic Bacteriology, it has become recognized throughout the world as the principal monographic work in the field of prokaryotic biology. Like a dictionary to a writer, the Manual is usually the first reference that a microbiologist consults when questions arise regarding the characteristics of an unfamiliar species or an unknown strain that bears some similarity to a more familiar one.
While the first edition has served the community well for many years, it has become outdated. As a result, the editorial board of Bergey's Manual Trust, in collaboration with more than 500 of the world's leading authorities in prokaryotic systematics, is in the process of revising Bergey's Manual of Systematic Bacteriology so that it reflects current thinking and advances in the field.
With this information, we can conclude that Phylogenetic classification is now broadly accepted as the preferred method of representing taxonomic relationships among prokaryotes and eukaryotes alike.

The study of a living being is called biology. There are two types of species that are living and these rare plants and animals.
The correct answer is described as follows
<h3>What is taxonomy?</h3>
- The classification of the species and arranging them into different hierarchy levels is called taxonomy.
The criteria for the classification is changed over periods of time and still changing as we are developing in modern science.
The first classification has used the habitat to classify the species. After that various scientists came they start to classify the species in a different manner.
The other classification is based on the cell wall and cell organization.
After that, the final classification is based on the 5 different criteria out of which the criteria are:-
- cell level
- cell organisation
- mode of nutrient
- mode of reproduction
- tissue level
Hence, the answer is mentioned as described.

Answer:
Explanation:
The world is in constantly changing, as in life, the beings living on this planet and the whole system that we are in synergy with and that is part of the life and existence of each being. These changes are the phenotype, the genotype of each being, as the changes and alterations due to environmental and internal transformations. The cells are in constantly changing, walking together with the weather, temperature, climate change by natural and man-made means, genetic mutation and natural selection.
Natural selection acts on the phenotype, or observable characteristics of an organism, such that individuals with favorable phenotypes are more likely to survive and reproduce than those with less favorable phenotypes. Gradually, the idea of plurality of existing species was developed and obtained from the evolutionary process, where natural selection prioritized some intraspecific variations through the struggle for survival of the fittest.
