Bacteria and Viruses are the main objects of study in the field of genetics for two reasons: bacteria are chosen because of their simplicity. Viruses are an interesting area of study because they survive by placing their own genetics into other organisms. This gives rise to the possibility of transplanting foreign and possibly beneficial DNA and RNA into hosts that previously did not have those helpful genes.
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
No - the main goal of genetic engineering - is to eliminate weaknesses in the subject organism. Example 1 - Creating a strain of wheat that is resistant to disease False A+ls - Awesomeness399 :P

Probably because there is no need, or use, to create several objects based on the main class.
Main method in java is always static as main method id the only method from where the program execution starts,and as we all know that main method is defined inside a class so JVM needs to make a object of the class to call the method and objects are build inside the main method ,so to execute the main method it has to make objects of the class but objects are build inside main method so that's the reason that main method is static so that JVM can execute the main method without making its object as static members can be called by class anme only
Easy answer: Bacteria are alive and viruses probably are not.
Bacteria are single-celled organisms that can replicate themselves. By this, I mean that they have all the genetic material to replicate (DNA & RNA). Viruses, in contrast, contain a piece of genetic material that is encapsulated by a protein coat known as a capsid. Because viruses only have a portion of genetic material, they have to infect a host organism and inject its material into the host and use the host to do the work for the virus. Since bacteria can "live" on its own and viruses cannot, bacterial infections can be treated with medications while viral cannot. In comparison of size, viruses are about 100 times smaller than bacteria. About of 90% of known bacteria live in a symbiotic relationship with humans. This means that the presence of bacteria is beneficial to both the bacteria and humans. In comparison, most viruses feed of the host to produce more viruses... therefore having no benefit to the host.

Microbes are sorted into these 4 groups: Viruses, Fungi, Bacteria and Protozoa
The three main types of microbes are fungi, bacteria and viruses. Bacteria are usually smaller than fungi and virus is the smallest type of microbe.
All bacteria are microbes, but not all microbes are bacteria. Viruses and fungi are the other two main types of microbes, or microorganisms.
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
Viruses require host cells, whereas cells provide their own replication mechanisms.
There are six major groups of microorganisms: Algae, Bacteria, Fungi, Helminths, Protozoa, and Viruses A mnemonic = All Boys Find Help Pronouncing Viruses In my book it says there are 5 Algea , Protazoa , Fungi, Prions and Viruses
Aerobiology is the study of organic particles. Some of the main concepts in aerobiology are bacteria, small insects, pollen grains, as well as viruses.
characteristic feactures of bacteria Bacteria: they are prokaryotic cells that absorb nutrients from the environment or produce their own nutrients, through light energy or other processes. In addition, bacteria have cell walls and plasma membranes for protection, DNA/RNA for function, and use Flagellum and their slime layer to move. Viruses: they are not cellular and aren't able to reproduce outside a host cell. they are obligate intracellular parasites. In addition, viruses are made of protein capsids, surface proteins, and DNA/RNA to inject into the host cell.
