Phagocytosis. This involves the complete engulfing of a extracellular particle or cell to form a intracellular phagosome. The phagosome then fuses with a lysozome to form a phagolysozome. The lysozymes in the phagolysozome digest the particle or cell (this case Paramecium). The other type of endocytosis is called pinocytosis.
A virus is not a living thing. It is made of genetic material inside a protein coat. A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. It is an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
The study of artificial selection by Darwin helped him to establish his theory of evolution via natural selection. One of the animals Darwin examined in detail was the domestic rock pigeon. In the 1850s breeding of pigeons was an ancient past time, thus, Darwin decided to keep and breed the pigeons by himself.
While studying pigeons, Darwin established scrupulous determinations of their skeletons and wondered at the breeds' distinct colors, behaviors, and proportions. He also observed the patterns of inheritance of various features, and he demonstrated that birds of very distinct breeds can, however, generate fertile offspring. Thus, supporting the theory that they all originated from a single species.
