Reversible (but Tight) Binding to an Antibody An an-tibody binds to an antigen with a Kd of 5 3 10□8 M. At what con-centration of antigen will Y be (a) 0.2, (b) 0.5, (c) 0.6, (d) 0.8?

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
