Review of Related Literature HISTORY OF VERMICOMPOSTING Vermicomposting‚ as an industrial process‚ was originally developed to remove unwanted organic materials from the agricultural and industrial waste streams. The derived product: earthworm castings‚ is now recognized as a high value material which‚ when blended with soil‚ can restore soil tilth by correcting the imbalances caused by the over-utilization of petrol-chemical based fertilizers; thus enabling crops and plants to naturally combat pests

is survival. Nervous system structures vary in the animal kingdom. In lower forms of animals‚ we can see different types of nervous systems. Cnidarians have a network of loosely arranged nerve cells throughout their bodies‚ forming a nerve net. Flatworms such as planarians exhibit a rudimentary brain with nerve cords traversing the length of their bodies. Mammals have highly evolved nervous systems. They have large brains which process information and sense organs located near the brain. The human

Cysticercosis is a disease caused by ingestion of the eggs of Taenia solium. Neurocysticercosis occurs when the tapeworm parasite infests the central nervous system (CNS). This infection is becoming increasingly common in places such as‚ Latin America‚ Central America‚ and Southeast Asia. Immigration has increased the area of infection and stopped the confinement to certain geographical areas. These infections occur via fecal-oral route and can come from fresh produce. Most of the infections can

Forensic entomology is using insect biology to determine specific aspects of a crime. It can be used to determine time of death‚ whether or not a body has been moved‚ and also if the victim had been intoxicated with any substances. Insects are also prime examples of Locard’s principle when solving a crime. The history of forensic entomology dates back to as early as the thirteenth century‚ and is still been developed today. There have been many cases involving forensic entomology to help solve

Task one A). How do living things interact? Living things find a way to live off the land. Not with artificial flavouring or stuff like that. But it may not last unless we take good care of it. Living things interact by: 1). Viruses Learn about viruses and their surroundings‚ and how they are created. What is a Virus A virus s a small‚ NONLIVING particle that invades and then reproduces inside a living cell. Viruses are considered nonliving because they are not cells. They cannot: * use energy

Asexual Reproduction in Animals Group 3 Nina Bansil Kenneth Calabia Josef Franz Cruz I. Introduction Asexual reproduction is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. Only one parent is involved in asexual reproduction. A more stringent definition is agamogenesis which refers to reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚ bacteria‚ and protists

Infection Control in the Workplace Every health care worker plays a vital part in helping to minimise the risk of cross infection – for example‚ by making certain that hands are properly washed‚ the clinical environment is as clean as possible‚ ensuring knowledge and skills are continually updated and by educating patients and visitors. Standard precautions (formerly known as universal precautions) underpin routine safe practice‚ protecting both staff and our residents from infection. By applying
