Answer:A. Protists B. Bacteria C. Animals D. Plants E. Fungi F. Archaea
Explanation:viruses are small non-living particles that contains hereditary materials.viruses attack cells of other organisms such as plants , bacteria ,archaea etc.
Viruses are acellular and contains either DNA or RNA.they cannot synthesis protein as they lack ribosomes ,so they use the ribosomes of the cell they have invaded to synthesize they proteins they need.
A virus usually has a central core surrounded by an outer protein coat called capsid.
Viruses can reproduce only within the living host cells and they are specific to the type of cells they attack.they attack plants through insect vectors or through openings on the plants.
Viruses can affect bacteria by injecting their nucleic acids through the cell wall and into the bacteria cell.such viruses are called bacteriophages.
A) <u>Mutation</u> is the original source of variations for plants and other organisms which develops differences among their respective species
Explanation:
Genetic variation leads to the natural differences between each individual and among individuals of a species. The main cause for this variation is due to alleles that cause variations in the composition of genes or the DNA sequences.
A mutation is a genetic variation which leads to the creation of a new allele in a species population. Each variation in the DNA sequence leads to an allele formation and each allele leads to a difference in character or trait between individuals since they are the alternate version of the original genes.
Although genetic variations could be brought about by crossing over, random fertilization, or independent assortment; mutation is the original source because it provides the basic raw material for all the evolutionary changes.
