½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the

Abdominal Aortic Aneurysms (AAA) are usually asymptomatic and found incidentally on ultrasound‚ CT‚ or on physical exam as a pulsating abdominal mass. If becoming symptomatic‚ most commonly it presents as mid-abdominal pain that radiates to the lower back. Pain could be constant or intermittent‚ or be worse with pressure applied to the area. Severe pain and a tearing sensation felt in the back is associated with dissection and should be treated as an emergency. AAA are more often found in older males

He is most famous for his ready-made artwork called “Fountain” 1917‚ a urinal which was not made by Duchamp‚ the only modification made to the urinal was a signature signed by Marcel Duchamp which was not his. This caused controversy over whether this was really an artwork. In saying this‚ Marcel Duchamp‚ his ready-mades (‘Bicycle Wheel”1913 and “Fountain”1917) and the use

The geological record does not support Darwin’s theory because there are no intermediate species found in fossils and sometimes groups display abrupt modifications. However‚ this can be the result of changes in the earth’s surface‚ unfitting conditions for fossil formation‚ the destruction of existing fossils‚ and the lack of discovery of fossils. Darwin uses these possibilities to argue against the naturalists

Additionally‚ undesired modifications may lead to the functional loss of a particular gene and also result into reduced fitness of the edited cells. 2.
