threshold wavelength where photoelectrons have no energy, i.e. Work function = hc/wavelength.Rearrange for wavelength and substitute. Wavelength = 2*10^-7 m.

There are 4 stages to the response of B lymphocytes upon contact with antigens. These are antigen presentation, clonal selection, clonal expansion and differentiation. During antigen presentation the lymp...

C10H22 (l) + 11.5O2 (g) --> 10CO(g) + 11H20 (g)Incomplete combustion so the products are CO and H2O, remember to include state symbols as the question asks for gaseous products.

Diffusion is the process where water molecules move from a negative water potential to a more negative water potential through a semi permeable membrane.

Using the elimination method to remove the variable x, we need both equations to have the same values of x. To do this we find the lowest common multiple of the x values: the lowest common multiple of 3 a...
