greek words: cyto- cell‚ and metry - measurement. So cyto-metry is about making cell measurements. To elaborate‚ flow cytometry is a technique for analysing particles (cells in this case) which are suspended in a fluid stream by flowing the cells past an interrogation point. A light source is directed on to a hydrodynamically focused stream to create a zone for interrogation. As cells flow through this interrogation zone they scatter the light‚ at this point any fluorescent compounds that are inside

the fish species by destroying their homes. Overexploitation is a huge risk‚ and this became very evident when the wolf population in Yellowstone was wiped out. Every wolf was hunted and killed in Yellowstone‚ and once the wolves were gone‚ the ecosystem became very unbalanced and many species started to either die out or be overpopulated. As for methods to help sustain species‚ core reserves and wildlife corridors are very effective methods. Core reserves are natural areas for organisms away from

Ecosystem Preservation versus Conservation Earth is composed of many different ecosystems and each one is a "dynamic complex of plant‚ animal‚ and micro-organism communities interacting with the non-living environment as a functional unit" (Protecting Threatened Ecosystems‚ 2004). These ecosystems are an intricate part of the human lifecycle as they provide us with our water‚ food and energy. Since mankind is in a take and take some more relationship with the ecosystems‚ many of them have had their

The main ecosystem I will focus on will be the habitats that tigers live in. More specifically I will focus on the effects that tigers have on their ecosystem and what would happen if tigers we to unfortunately go extinct. The tiger is one of the biggest components in its ecosystem besides for humans. Without tigers in their ecosystem their environment would completely fall
