We have decided to start an intervention to help older adults experiencing loneliness. We have paired these older adults up with young professionals who visit them at least twice a month and talk to them on the phone once a week. We want to see how this is impacting the loneliness score of both parties to see if we should roll this out at other facilities.  What type of research design would be best here: case study, descriptive, or experimental? Why? What sorts of results will I get? Make sure to include the scenario in your answer.

The trade name of gabapentin is Neurontin.

What is the role of histone acetyltransferase (HAT) in chromatin remodeling? (a) Removes acetyl groups to silence genes.  (b) Adds acetyl groups to activate gene expression.  (c) Breaks DNA strands to enable transcription.  (d) Binds transcription factors to recruit RNA polymerase.

Which of the following statements about reaction orders in the rate law expression is correct? Select all that apply.  

A chemical reaction with dinitrogen pentoxide (N2O5) occurs where the rate law expression was determined to be rate = (0.080 1/min)[N2O5]. If the initial concentration of N2O5 is 0.30 M, what is the concentration after 2.6 minutes of reaction?

Consider the chemical reaction shown below and the experimental data obtained for this reaction to answer parts A-E below. Part A: calculate the order with respect to S [blank1] Part B: calculate the order with respect to O2 [blank2] Part C: calculate the overall reaction order [blank3] Part D: calculate the specific rate constant for this reaction. Round your answer to 1 decimal place and do not include units in your answer.  [blank4] Part E: which of the below options (a-e) are the correct units for the rate constant in part D? Type your letter answer (lowercase) in the box below. [blank5] a. 1/Ms b. 1/Ms2 c. 1/M2s d. M/s e. M2s

The statement CREATE VIEW view_sa3ASSELECT *FROM vendorsWHERE vendor_state NOT IN (“CA”,”MI”,”WI”,”AZ”);

The statement CREATE VIEW view_sa3ASSELECT vendor_name, AVG(invoice_total) AS avg_of_invoicesFROM vendors JOIN invoices ON vendors.vendor_id = invoices.vendor_idGROUP BY vendor_nameHAVING AVG(invoice_total)>21ORDER BY vendor_name;

When this query is executed, the result set will contain SELECT vendor_name, COUNT(*) AS number_of_invoices,        AVG(invoice_total – payment_total – credit_total) AS balance_due FROM vendors v   JOIN invoices i   ON v.vendor_id = i.vendor_id  WHERE (invoice_total – payment_total – credit_total) >=     (SELECT AVG(invoice_total – payment_total – credit_total)     FROM invoices) GROUP BY vendor_name ORDER BY balance_due DESC;

When this query is executed, the result table will contain one row for SELECT i.vendor_id, MIN(i.invoice_total) AS smallest_invoiceFROM invoices i    JOIN      (SELECT vendor_id, AVG(invoice_total) AS average_invoice     FROM invoices     GROUP BY vendor_id     HAVING AVG(invoice_total) >=88) vendors_temp   ON i.vendor_id = vendors_temp.vendor_idGROUP BY i.vendor_idORDER BY smallest_invoice;
