TYPES OF BEAKS IN BIRDS

Introduction : Types of Beaks in Birds The entire modem avian world is characterized by the absence of teeth. The upper and lower jaw bones become elongated to form a peculiar beak or bill covered by a horny sheath called as rhamphotheca. The modification of forelimbs into wings deprived birds of some of their normal

Spermatogenesis Spermatogenesis can be studied through histological preparation of tissues (testis) or by squash technique or heat dry Giemsa technique. For histological studies, testis of Albino rat is taken out after chloroforming rat. After fixing testis is 10% formaline, its sections are cut through microtomy process. Stain sections in haematoxylin and eosin, dehydrate, clear in
