Plot the three isotherms on a log-log scale. b. Plot the heat of adsorption as a function of coverage. c. Is the Langmuir adsorption isotherm a good assumption?

Lamarck believed that an individual could acquire phenotypic changes during their lifetime, and those changes would be passed on to the offspring. Choose the statement below that describes the problem with this idea, but why we still consider Lamarck's idea a contribution to evolutionary thinking. Acquired traits are not heritable, but Lamarck's idea was important because he verified Darwin's process of natural selection. Acquired traits are heritable, but not part of the genetic makeup of the organisms. Acquired traits are not heritable, but Lamarck's idea was important because he was the first to propose a process for evolutionary change.

Acquired traits are heritable, and Lamarck's idea was important because he proved that Darwin's idea of variational evolution was incorrect.

Required information Potential Misstatements in the Revenue Cycle Read the overview below and complete the activities that follow. The revenue cycle is a major cycle for most companies. Accounts receivable, revenue, and other accounts are tested through this cycle. Often there are misstatements found, including errors and/or fraud by the client. CONCEPT REVIEW: It is important in testing any cycle, especially revenue, to realize that misstatements will occur and to try to distinguish between errors and fraud. Many instances of misstatement are based on the inappropriate recognition of

A block of polyisoprene rubber with a square cross-sectional area of \( 25 \mathrm{~mm}^{2} \) and length of 40 cm is stretched using a tensile force of 10 N . The tensile strain on the rubber is 0.20. The sides of the block shorten the same amount because of the square crosssection. The molar density of the polyisoprene is \( 9.1 \times 10^{-5} \mathrm{~mol} / \mathrm{cm}^{3} \). a. Calculate the work per unit volume and the total work done on the rubber if the stress was applied at room temperature. b. Estimate the molecular weight between crosslinks for this sample. c. If the Young's modulus of this sample is a good estimate of the plateau shear modulus and the density of polyisoprene is \( 0.91 \mathrm{~g} / \mathrm{cm}^{3} \), what would be the entanglement molecular weight for this sample? d. Find the actual entanglement molecular weight of polyisoprene. Is the Young's modulus an over-estimate or under-estimate of the plateau shear modulus?

You are the Director of Procurement and had oversight for the sourcing processes regarding a turnkey project that resulted in the award of a contract for the design, construction, installation, testing and commissioning of a new electricity transmission substation at APAM. The civil works lot within the entire programme of works approved, leading to the award costs Gh2.5m. the contractor is currently onsite and had initiated a change request (CR) in respect of additional works that will expand the civil works scope. The said CR had gone through the project management change control governance regime and the said CR had been approved from a technical perspective. REQUIRED: a) Assuming that the total project cost was Ghs10.07m, determining the approving authority for the tender outcome/recommendation. b) From a commercial perspective, and as the Procurement lead, outline the cause of action(s) and the methodology you would use to ascertain the total cost of the approved CR from the Project Change Control Board.
