With the aid of clear sketches, highlight two major difference between homogeneous and heterogeneous nucleation. b) The iron–iron carbide eutectoid reaction is and is fundamental to the development of microstructure in steel alloys. On cooling, austenite, with an intermediate carbon content, transforms to a ferrite phase, having a much lower carbon content, and also cementite, with much higher carbon. Figure 4.1 is a temperature-timetransformation (TTT) diagram for the said process at 675℃. i. Determine how long it takes for austenite...

Formins can promote actin filament assembly via nucleation. This has been shown to occur directly under the plasma membrane in response to activation of membrane receptors. a) What major class of proteins is responsible for recruiting formin to the membrane and activating it? b) How many formin proteins are needed for nucleation to begin? c) What other actin-binding protein can bind to formin to promote nucleation?
