Question Consider a perfectly competitive market where the demand for the good is given by Q=761-5p, where Q denotes the quantity demanded at price p. On the supply side, the industry supply function is given by Q=-8+7p. The government imposes a per-unit tax on consumers equal to t=7.761 Derive the market equilibrium in the presence of this tax. Determine the share of the tax paid by consumers and enter it below. (Remember that you must always enter just a number in decimal form.)

A researcher is interested in the proteins that E-cadherin binds to. She expresses full-length E-cadherin as well some truncated constructs of the protein in a mouse cell line that does not express any other cadherins. The scheme of constructs is shown in figure A, (E represents the extracellular domain, TM the transmembrane domain and C the cytoplasmic domain). She labels the cells with 35S methionine for 16 hours, homogenizes them in detergent, and an antibody raised against the extracellular domain of the cadherin E-cadherin to pull-down (co-immunoprecipitate) E-cadherin and any associated proteins. She then analyses the immune precipitates by electrophoresis by SDS-PAGE, followed by autoradiography to make the labelled proteins visible. In lane 1 of figure B, the antibody precipitates three major proteins in cells transfected with a plasmid expressing the full-length intact cadherin. These proteins are not precipitated from untreated control cells.
