Use the Law of Cosines to determine the indicated angle theta (in degrees) shown in the following figure. (Round your answer to one decimal place.)theta =

An archery bow is drawn a distance d = 0.55 m and loaded with an arrow of mass m = 0.094 kg. The bow acts as a spring with a spring constant of k = 191 N/m, and the arrow flies with negligible air resistance. To simplify your work, let the gravitational potential energy be zero at the initial height of the arrow.

Part E Choose the explanation why certain mutations in the regulator gene (

) of the lac system result in maximal synthesis of

-galactosidase, permease, and transacetylase even in the absence of the inducer (lactose). Such mutations provide modified proteins that associate with the promoter activating transcription. Such mutations provide modified proteins that associate with the promoter not allowing transcription to occur. Such mutations provide modified proteins that associate with the operator activating transcription. Such mutations provide modified proteins that are unable to associate with the operator to shut off transcription.

14. (20 pts) (a) Provide a plausible curved arrow mechanism for the reaction below. Be sure to draw structures for all key intermediates and major products (organic and inorganic), and show formal charges and electron flow with curved arrows. All curved arrows must begin from either a bonding pair or lone pair of electrons. (b) Identify all the proton transfer steps in the mechanism and provide their mechanistic purposes. Follow the examples in the lecture note.
