Darwin called the ability of an organism to survive and reproduce in its environment fitness.
Some organisms were fit to do all of these things, whereas others were not.
Non-human life differs from that because the environments are covered with like sewers, buildings, and roads. Green spaces such as parks, backyards, and undeveloped lots are scattered in among the developed areas instead of all connected together. Plants and animals have to deal with exposure to toxins from vehicles and loss of habitat and food sources.
<span>Cells are difficult to see in light microscopy,so to help visualize the structure of cell ,dyes are used to impart a particular color to cells.
Eukaryotic cells have both acidic and basic components so,
Hematoxylin and Eosin staining is the standard method of staining used for an eukaryotic cell.
Hematoxylin is a basic dye that binds to negatively charged DNA and RNA and is blue in colour.Eosin is pink in color and it binds to positively charged particles like the mitochondria and other components of cytoplasm.</span>
