DNA sequences from virtually any living organism could be inserted into a bacterium and the bacterium would be able to use the sequences to make the same proteins that the original organism did. In what way does this provide evidence for evolution? (4 points) Since bacteria are able to use DNA from other organisms, they must have evolved from them as a common descendant. Bacteria must be less evolved than higher organisms, since they can still make proteins from the DNA of other organisms. Since foreign DNA was added to the bacteria, it evolved beyond higher organisms. Since the genetic code is the same across species, these species must have inherited it from a common ancestor.

Mid-Level Exercises MyITLab - Metropolitan Zoo Gift Shop Weekly Payroll Grade Analysis As the manager of the gift shop at the Metropolitan Zoo, you are responsible for managing the weekly payroll. Your assistant developed a partial worksheet, but you need to enter the formulas to calculate the regular pay, overtime pay, gross pay, taxable pay, withholding tax, PICA, and net pay. In addition, you want to include total pay columns and calculate some basic statistics. As you construct formulas, make sure you use absolute and relative cell references correctly in formulas. Open the c02mPgrol workbook and save it as e02mPayroll_LastFirst. Study the worksheet structure and read the business rules in the Notes section. Use IF functions to calculate the regular pay and overtime pay based on a regular 40-hour workweek in cells ES and FS. Pay overtime only for overtime hours. Calculate the gross pay based on the regular and overtime pay. Abram's regular pay is $398. With 8 overtime hours, Abram's overtime pay is $119.40. Subtract the deduction per dependent and subtract that from the gross pay. With two dependents, Abram's taxable pay is $417.40. Use a VLOOKUP function in cell 15 to identify and calculate the federal withholding tax. The VLOOKUP function returns the applicable tax rate, which you must then multiply by the taxable pay. Calculate FICA in cell J5 based on gross pay and the FICA rate, and calculate the net pay in cell K5. Copy all formulas. Use Quick Analysis tools to calculate the total regular pay, withholding tax, FICA, and net pay on row 17. Apply Accounting Number Format to the range C5:C16. Apply Currency Number Format to the range D5:D16. Use the Format Cells dialog box to apply Top and Double Bottom Borders to the range C5:K16. Add a statistics area (the range C12:K23) and format the calculations as Number format with 2 decimal places for the totals. Add a title on the left side. Save and close the workbook. Based on your instructor's directions, submit the e02hLoans2c workbook.

You want to confirm if this table is in normal forms. Which answer is FALSE? Student ID Last Name First Name Phone No License No Ticket No Date Violation Code Violation Type Fine 15634 10/17/10 2 No parking permit $25 38249 Brown Thomas 111-7804 BRY 123 16017 11/13/10 1 Expired parking meter $15 14987 10/05/10 3 Handicap violation $100 82453 Green Sally 391-1689 TRE 141 16293 11/18/10 1 Expired parking meter $15 17892 12/13/10 2 No parking permit $25 This is not in the 3rd normal form because there are two columns that depend on the non-key column, Violation Code. This is not in the 2nd normal form because violation date and code are independent of student ID. This is not in the 2nd normal form because the student information doesn't depend on all the primary keys. This is not in the 2nd normal form because there are non-key attributes determining the fine. This is not in the 1st normal form because there are multiple values in a row.
