Horns vs Antlers : the Key Differences
Horns vs Antlers : the Key Differences :- Among the many remarkable adaptations found in nature are horns and antlers. Due of their initial similarity, these remarkable structures are frequently mistaken for one another. But in terms of form, development pattern, function, and the animals that have them, horns and antlers are quite different. The… Read more: Horns vs Antlers : the Key Differences
Modifications of Aortic Arches in Vertebrates
Modifications of Aortic Arches in Vertebrates Modifications of Aortic Arches in Vertebrates :- Basic embryonic plan. In a typical vertebrates embryo, the major arterial channels include a ventral aorta, a dorsal aorta and usually 6 pairs of aortic arches connecting ventral aorta with the dorsal aorta. Blood leaves the heart through ventral aorta which runs… Read more: Modifications of Aortic Arches in Vertebrates
Circulatory System in Vertebrates
Circulatory System in Vertebrates Circulatory System in Vertebrates :- In order to carry on vital life processes, all animals, from the simplest protozoans to the most complex vertebrates, required that — (1) Food absorbed through digestive tract and oxygen collected in respiratory organs, must be transported to all parts of the body, continually, for metabolism.… Read more: Circulatory System in Vertebrates
Hantavirus: Symptoms, Causes, Prevention
Introduction Hantavirus is a rare but potentially serious viral infection that spreads mainly through contact with infected rodents and their droppings, urine, or saliva. Although uncommon, hantavirus infections can become life-threatening if not diagnosed and treated early. Increased awareness about rodent-borne diseases and recent global discussions around hantavirus outbreaks have made it important for people… Read more: Hantavirus: Symptoms, Causes, Prevention
Respiratory System in Vertebrates
Respiratory System in Vertebrates Respiratory System in Vertebrates :- Every cell in a living organism consumes oxygen (02) during oxidation of substances resulting in the release of heat and energy and production of carbon dioxide (C02). This C02 acts as a poison for protoplasm unless removed from the body. The term respiration is used in… Read more: Respiratory System in Vertebrates
Digestive System in Vertebrates
Digestive System in Vertebrates Digestive System in Vertebrates :- Oxygen, water and food are necessary for the continuance of life. 02 enters the body through the agency of respiratory system, but water and food are first taken into the digestive tract of every living being. Associated with the tract are its derivatives or accessory organs,… Read more: Digestive System in Vertebrates
Integument or Skin and its Derivatives in Vertebrates
Definition of Integument The term integument is applied to the outermost protective covering of the animal body, the skin, and its various derivatives. Skin also includes the conjunctiva of eyeballs and external surface of eardrums. It is directly continuous with the mucous epithelial lining of mouth, rectum, nostrils, eyelids and urinogenital ducts. Functions of integument… Read more: Integument or Skin and its Derivatives in Vertebrates
Types of Feet in Birds
Types of Feet in Birds The types of feet in birds are also modified variously in accordance with the character of the environment and the manner of locomotion 1.Cursorial or running feet :-In running birds, the legs are powerful and the number of toes is reduced. The hind toe may be elevated, reduced or absent.… Read more: Types of Feet in Birds
Placenta in Mammals (Placentation)
Placentation in Mammals What is Placenta Modes of embryonic nutrition differ in different mammals. Prototheria or monotremes (Tachyglossus, Ornithorhynchus) are oviparous like most reptiles and birds. They produce large, heavily yolked and shelled eggs. The vitelline vessels developed in the wall of yolk sac carry yolky nutrients to the developing embryo. There is no uterine… Read more: Placenta in Mammals (Placentation)
Apis indica (Honey Bee)
The Indian honey bee, Apis indica, is a subspecies of the Asian honey bee. In India, Pakistan, Nepal, Myanmar, Bangladesh, Sri Lanka, Thailand, and mainland Asia, it is one of the most common bees encountered and domesticated. It is perfect for beekeeping because it is generally non-aggressive and seldom displays swarming behavior. It resembles the… Read more: Apis indica (Honey Bee)
Melolontha (Beetle)
The genus Melolontha belongs to the Scarabaeidae family of beetles. This genus includes the European cockchafers. Insects classified as beetles belong to the superorder Holometabola and the order Coleoptera. They differ from most other insects in that their first pair of wings are hardened into wing-cases, or elytra. With over 400,000 recognized species, the Coleoptera… Read more: Melolontha (Beetle)
Moth
Moth belong to the order Lepidoptera, which also includes butterflies. Moths are distinguished by their dark or dull-patterned wings. The group is paraphyletic with regard to butterflies (suborder Rhopalocera), and neither subordinate taxon is used in current classifications. Previously, they were classed as suborder Heterocera. The great majority of the order consists of moths. Moths… Read more: Moth
