1) Hunting
Hunting for food (subsistence hunting) trade (commercial hunting) and fun (sport hunting) has resulted in the decrease of species. Examples: Dodo, cheetah, musk deer and blue whale..

These cancers are located in the epithelial lining of internal organs or glands. For e.g., Breast cancer, Stomach cancer etc., Cancers of epithelial glands are called Adenoma. About 85% of all tumours are of this kin..
1) Morphallaxis
In this type, regeneration occurs mainly by the remodelling of existing tissues and the re-establishment of boundaries, thus involving very little new growth. As a result, the regenerated individual is much smaller initially. It subsequently increases its size and becomes normal after feeding. This..

It is a positive inter specific interaction in which both the partners are mutually benefitted and increase the chance of their survival. However, the interaction is not obligatory for their survival as both can live without this interaction. For e.g., a) Crocodile bird (Pluvianus aegyptius) enter..

These chromosomes occur in the oocytes (germcells in the ovary) of amphibians and in some insects. They are extremely large synapsed homologous chromosomes which can be seen in the diplotene stage of prophase-I in meiosis. They measure about 1500 to 2000 in length. A lampbrush chromosome consist..

These are many organisms which appear different in their developmental stages. For e.g., a) Frogs and Salamanders The adult and larval stages of frogs, toads (tadpole) and salamander (axolotyl) do not resemble in structure and function. Tadpole larva of frog is a fish like larva fou..
