cell‚ allowing it to survive and participate in the functioning of the larger organism. http://micro.magnet.fsu.edu/cells/plantcell.html Animal cell The animal cell is a typical eukaryotic cell. It ranges in size between 1 and 100 micrometers and is surrounded by a plasma membrane‚ which forms a selective barrier allowing nutrients to enter and waste products to leave. The cytoplasm contains a number of specialized organelles‚ each of which is surrounded by a membrane. There is only

Chromosomes in prokaryotes consist of a single nucleic acid molecule which can be either DNA or RNA. There is comparatively little genetic material for example E.coli genome is 1200 micrometres while a single human chromosome is between 12000 and 73000 micrometers in size. Unlike in eukaryotes the genetic material in viral prokaryotes can be single or double stranded RNA or DNA. It can also be linear or circular. Only in viruses can the genetic material be RNA. For example in HIV the virus can infect a host

Fitness Testing Flexibility- For flexibility you can do the sit and reach test. The advantages of this are it is relatively cheap‚ not much equipment is needed apart from a box with measurements on and a magnet to move on it. A disadvantage for the traditional sit and reach procedure is that people with long arms and/or short legs would get a better result‚ while those with short arms and/or long legs are at a disadvantage. The modified sit and reach test controls for this‚ as the zero mark is

The infrared spectrum yields direct information about the presence or absence of key functional groups. "The region of the infrared spectrum which is of greatest interest to organic chemists is the wavelength range 2.5 to 15 micrometers which correspond to approximately 4000 to 600cm-1"(Young). "When atoms or molecules absorb light‚ the incoming energy excites a quantized structure to a higher energy level. The type of excitation depends on the wavelength
