Answer:
New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups
Hope it helps :)
Phagocytosis is when a cell encloses a particle completely to form a phagosome. The process was originally evolved for the acquisition of nutrients by certain specialised cells. In multicellular animals, the process has been adapted to form a part of the immune system. Here, debris and pathogens are ingested by a macrophage, which then fuses with a lysosome to form a phagolysosome. Here, enzymes and toxic peroxides digest the pathogen.
Answer:carbon, hydrogen, and sometimes other elements such as nitrogen, sulfur, oxygen, or phosphorus.
Explanation:
The speciation process is best defined as the development of a new species (c).
Very small things on the order of micrometers/smaller that cannot be resolved with a light microscope. Things like viruses, non mitotic DNA, certain bacteria/cells can only be resolved via an electron microscope.
