Why are catalysts used during the cracking process?
Generally platinium or palladium though other metals may be used. These are quite expensive metals. It's important these do not get "poisoned", ffor example in catalytic converters if lead fuel is used the lead will bond irreversibly to the metal and stop all sites where chemical reactions may happen on the surface. Whereas normally chemicals will chemisorb, react and the products will desorb due to volatility or the elevated temperature of operation.
Why are you not a big cell?
this is because inside a cell, substances move by diffusion, which is very slow, but will do on a molecular leveldiffusion is when particles move from a place where there are lots of them together, to where there are less particles or they are further apartdiffusion only works across small distances because it is so slowif you were just a big cell, nutrients diffusing into your surface would not travel quickly enough to get to the places where they are needed because the distances are too bigso cells have to be small ffor diffusion to be effectivealso, toxic waste products building up inside would not diffuse out quickly enough and would damage the systemsthis is why we have a complex intake and transport system, so we can get nutrients to the cells, and then toxic products can be removed quicklyAlso, the cells within your body have developed to be very different and perform specific roles, eg nerve cells which transmit signals. all these systems could not possibly be performed within one cell
How does a volcano affect the natural environment?
Volcanoes affect the earth in many ways. The first being that they destroy much of the area surrounding them and in some cases lower the earths temperature by many degrees. Earthquakes are a side affect of volcanoes. When a volcano explodes it covers the ground (most likely) with ash and or lava which over time turns into rock forming new land and rocks. It also can destroy cultures and preserve them like with Pompei. And animals and humans have lost their lives.
