Because electrons are “pulled” towards the oxygen.
Speciation is the
process by which new and distinct species are formed. One of the most important
factors necessary for speciation to occur is the genetic isolation of two
populations. This genetic isolation can, over long periods of time, cause these
two groups to become genetically incompatible. Factors that can lead to this
genetic isolation include geographic separation and hostility among population
groups.

Answer:D
Explanation:All things are made up of atoms but only living things are made of cells.
For staining flagella of bacteria use actively motile organisms 20 to 24 hours old, allow to diffuse in sterile water 20 to 30 minutes, transfer droplets of the suspension to clean slides and let evaporate without spreading. Then treat 2 to 4 minutes with the following mordant: tannic acid 10 or 20%, 50 cc.; ferric chloride 5%, 10 to 15 cc.; carbol fuchsin (Ziehl-Nielson), 5 cc.; hydrogen peroxide 3%, 6 to 8 cc. Wash and stain 2 to 3 minutes with a mixture of basic fuchsin, saturated alcoholic, 10 cc.; anilin oil (1 part) and 95% alcohol (3 parts) mixed, 5 cc.; distilled water, 30 cc.; acetic acid, 4%, 1 cc. Wash thoroly with water.
