Viruses are not considered living structures because they do not exhibit all the properties of life. While they can replicate and evolve, they lack the ability to carry out metabolic processes, respond to stimuli, or maintain homeostasis independently. Viruses rely on host cells to reproduce, making them dependent entities.
A viral species refers to a group of viruses that share similar genetic characteristics and are considered to be evolutionarily related. This classification helps in organizing viruses based on their genetic makeup and biological properties. Viral species are named and defined by the International Committee on Taxonomy of Viruses (ICTV).
The study of biology is based on the idea that there is a wide diversity of living organisms in the natural world, and that these organisms interact with each other and with their environment in complex ways. By understanding the structures, functions, and behaviors of living organisms, biologists aim to uncover the principles that govern life processes and the interconnectedness of all living things.
Viruses can only infect specific cells that have the necessary receptors on their surface for the virus to attach to. Each virus is adapted to infect specific types of cells based on these interactions. This specificity limits the range of cells that a virus can successfully infect.
Two branch types of chemistry are organic chemistry, which focuses on studying carbon-based compounds, and inorganic chemistry, which studies non-carbon-based compounds. Organic chemistry deals with the structure, properties, and reactions of organic compounds, while inorganic chemistry focuses on studying the properties and behaviors of inorganic compounds.
Molecules. Atoms combine through chemical bonds to form molecules, which are stable structures that exhibit unique physical and chemical properties based on the types and arrangement of atoms within them.
The grouping of viruses is based partly on their genetic material (DNA or RNA), mode of replication, morphology, and characteristics of their host cell. These factors help define different families, genera, and species of viruses. Additionally, viruses may also be grouped based on their structural and biochemical properties.

All life on earth is based on DNA except for some viruses which only have RNA.
kill viruses, bacteria, fungi, and parasites. This plant has many active compounds like triterpenes, proteins, flavonoids, alkaloids, and steroids. A group of amino acid-based proteins called MAPs protect against plant viruses.
Materials are composed of atoms and molecules that are arranged in specific patterns or structures. These atoms and molecules determine the properties and characteristics of the material. Common materials include metals, ceramics, polymers, and composites, each with unique properties based on their atomic structure and bonding.
This is likely a misunderstanding or confusion. California cities are not part of the periodic table, which lists elements based on their chemical properties and atomic structures.
The Seven Properties of Life:-made up of cells-reproduction-based on genetic code-growth and development-need for materials and energy-response to environment- maintaining internal balance
Viruses are typically classified based on their genetic material (DNA or RNA), protein coat structure, size, and mode of replication. They are categorized into families, genera, and species based on these characteristics. Classification of viruses is constantly evolving as new information is discovered about their genetic makeup and biological properties.

presence or absence of an envelope.
Each element in the periodic table has unique properties based on its atomic structure, such as number of protons, electrons, and neutrons. The differences in properties between elements are due to variations in these atomic structures, which affect the element's chemical and physical behavior.
