2 Main Types of Speciation | Evolution | Biology

Speciation is the method of formation of new species. A species can be defined as one or more populations of interbreeding organisms that are reproductively isolated in nature from all other organisms.

Absorption of Foodstuff in Human Body | Biological Processes | Biology

Absorption is the process by which the end products of digestion pass through the intestinal epithelium and enter the blood stream. Attempts have been made to explain the mechanism of absorption on the basis of known physico-chemical principles. The following factors are believed to be involved in the process: i. Diffusion: This depends upon the relative concentration of the substances [...]
