Water has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds‚ this raises its melting and boiling points‚ i.e. its boiling point would be -120¢ªC rather than 100¢ªC. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. <br> <br>Water has been called

like tiny sea animals‚ algae and waste. Sea cucumbers have eight to 30 tube feet around their mouths. With these tube feet‚ sea cucumbers feast. The sea cucumber scans the sands of the ocean floor for dead plant and animal remains‚ much like an earthworm would do on land. When the sea cucumber accidently swallows sand‚ they pass it out of their bottom. The sea cucumber moves very slowly across the ocean floor. Some kinds of sea cucumbers move their muscles slowly to get around‚ and some sea cucumbers

water plays a significant part in this. In plants water is responsible for making the cells of the plant turgid by osmosis and therefore providing support‚ particularly in the leaves of the plant. Animals with hydrostatic skeletons‚ for example the earthworm‚ rely on water for support. The pressure of the fluid (water) beneath the ring of muscles means that the animal cannot be compressed and therefore keeps its shape. A

Abstract Forensic science continues to shape the world of justice‚ fueling crime investigations and signifying the progress of modern technology. While forensic science encompasses a multitude of techniques‚ the literature to follow will focus on the art of forensic autopsy. Though autopsies are more often used for purposes unrelated to crime‚ they play such a crucial role in murder investigations‚ that this field of forensic science has a large impact on where the investigation should begin

CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

gases‚ organic matter‚ living organisms‚ and plants (Thien‚ 2002). The soil is said to be stable structurally and chemically thus is considered an outstanding medium for soil organisms such as bacteria‚ fungi‚ protozoa‚ nematodes‚ arthropods‚ and earthworms. The potential habitats of these soil invertebrates are the spaces within the surface litter‚ holes in soil aggregates and pore spaces‚ root channels‚ etc. Soil arthropods are vital link in the food chain as decomposers. They play important roles

introduction of European pigs to Hawaii had similar effects on the native species‚ although‚ due to a scarcity of protein in natural Hawaiian forests‚ the European pig population did not grow as rapidly as the goats until the 1900s with the introduction of earthworms and foreign plants which made up large portions of the pigs ’ diets (Stone and Loope 1987). European pigs and goats are both primarily grazing animals‚ meaning their diet consists mostly of plant life found near the ground. Rats‚ mice‚ and mongooses
