Is it ethical to feed live food to exotic pets? Abstract Live food items are often fed to exotic pet species whether they be birds‚ amphibians‚ reptiles or mammals. This raises issues of welfare‚ both of the animals fed live prey items and the prey itself. Concerns over live food welfare are particularly marked in the feeding of vertebrate prey items and evidence presented here shows the prolonged time taken for rodents to die‚ this fuelling these concerns. And yet the welfare of all exotic

Ebola Ebola is the virus Ebolavirus (EBOV)‚ a viral genus‚ and the disease Ebola hemorrhagic fever (EHF)‚ a viral hemorrhagic fever (VHF). The virus is named after the Ebola River Valley in the Democratic Republic of the Congo (formerly Zaire)‚ which is near the site of the first recognized outbreak in 1976 at a mission hospital run by Flemish nuns. It remained largely obscure until 1989 when several widely publicized outbreaks occurred among monkeys in the United States. The virus interferes

CHIKV has recently re-emerged causing millions of infections in countries around the Indian Ocean characterized by climate conditions favourable to high vector density. Importation of human cases to European regions with high density of suitable arthropod vectors (such as A. albopictus) may trigger autochthonous outbreaks. The clinical signs of CHIKV infection include non-specific flu-like symptoms‚ and a characteristic rash accompanied by joint pain that may last for a long time after the resolution

History of evolutionary thoughtFurther information: History of evolutionary thought The proposal that one type of animal could descend from an animal of another type goes back to some of the first pre-Socratic Greek philosophers‚ such as Anaximander and Empedocles.[11][12] Such proposals survived into Roman times. The poet and philosopher Lucretius followed Empedocles in his masterwork De Rerum Natura.[13][14] In contrast to these materialistic views‚ Aristotle understood all natural things‚ not

Cell Structure - Cell Organelles 1. What is cell theory? Cell theory asserts that the cell is the constituent unit of living beings. Before the discovery of the cell‚ it was not recognized that living beings were made of building blocks like cells. The cell theory is one of the basic theories of Biology. 2. Are there living beings without cells? Viruses are considered the only living beings that do not have cells. Viruses are constituted by genetic material (DNA or RNA) enwrapped by a protein

Consequently‚ no emphasis has been placed on the vagaries of sexual and asexual reproduction among various fungi in this Test Bank. Instead‚ new questions assess students’ abilities to think logically about fungal morphology‚ genetics‚ and ecology. Two new sets of scenario questions deal with the biology
