You may need to refer to the article ‘Liking’ is Believing from our weekly tasks. WEBSITE: ‘Liking’ is Believing   The study in the article examined the effect of social approval on people’s belief in fake news stories. The article reports: “Over 600 social media users participated in the two-part study. They were asked to look at two of the tweets, read the news stories linked to the tweets, and retweet the one they thought that others should read, adding an original comment encouraging others to do so. Up to 20 UCSB undergraduate research assistants “liked” the retweets — that is, clicked a heart under each message — in specific, randomly assigned amounts. Some tweets received no hearts, while others received 5, 10, 15 or 20.”   Identify the population  of the study

Electric airplanes, including passenger electric airplanes, are on the horizon. Airplanes are now being powered by electric battery power. The next two questions will ask you about corporate business diversification strategies we studied that an existing company can pursue into new industries. Each answer must apply a different corporate business diversification strategy and you must select a unique company for each answer.   In total, you will identify two different corporate diversification strategies into new industries and a relevant company for each strategy. Using one type of corporate diversification strategy for an existing company, identify an existing company that would use this type of corporate diversification strategy to compete in the electric airplane industry. Apply that corporate diversification strategy the company would use by explaining why that strategy is relevant in these circumstances and how that company would pursue it. Using a different type of corporate diversification strategy for a different but existing company, identify that other company that would pursue this type of corporate diversification strategy to compete in the electric airplane industry. Apply that second corporate diversification strategy this other company would use by explaining why this diversification strategy is relevant in these circumstances and how this other company would pursue it.

Full 360° Room Scan You must perform a slow and complete 360° scan of your entire testing environment using your webcam or laptop camera. This step helps ensure exam security and must be done properly. Instructions: Pick up your camera (or rotate your laptop carefully) and slowly show the entire room. Include: The desk surface Under the desk Behind your monitor/laptop Ceiling and floor area Move slowly and steadily—do not rush this step. Check your second (side-angle) camera, ensure it’s already positioned and clearly showing your side profile, desk, hands, and screen. An incomplete or rushed scan will result in your test being flagged for review. Click ‘Next Question’ once you have completed this step.

You are running an enzyme assay that uses the co-enzyme NAD. Its activity is measured in terms of NADH produced. You have obtained the following data: Total volume of assay is 3.0 mL Sample volume is 0.5 mL Absorbance change 7 minutes is 0.350 The molecular extinction coefficient of NADH is 6.22 x 10-3 L/μmol-1/cm-1 and the light path is 1 cm. Calculate the enzyme activity in IU/L.

You are given a series of 6 tubes. In the first tube is 4.5 mL of saline. In each of the following tubes is 6 mL of saline. 0.5 mL of serum is added to the first tube and 2 mL of this is then transferred to each of the following tubes. The final 2 mL is discarded. The total (substance) dilution in tube #3 is:

You are making up a standard curve for an albumin assay. The standard values that are needed are: 1.0 g/dL; 2.0 g/dL; 4.0 g/dL; 6.0 g/dL; 8.0 g/dL; and 10.0 g/dL. You have at your disposal 100 mL of a 30 g/dL stock solution. What is the volume of stock and dilution needed to make 5 mL of the 2.0 g/dL standard?

0.5 mL of serum is used in an ALT test. The change in absorbance is measured at 340 nm using a 2 mL reaction mixture. The initial absorbance reading was 0.63. The reading after 3 minutes was 0.41. What is the ALT in IU?

Convert 750 microliters to milliliters.

Which is NOT an interference for the urine reagent strip test for leukocyte esterase?

A quantitative D-dimer immunoassay test is performed on a patient using an automated instrument. The value is 1160 ng/mL (110-240 ng/mL). Which of the following best fits this result?
