Solution Steps

Step 1: Identify the plant structures

The images depict cross-sections of a _Tradescantia pallida_ stem at increasing magnification. We need to identify the labeled structures.

Step 2: Determine the structures based on location and morphology
  • A: Cuticle
  • B: Epidermis
  • C: Cortex (parenchyma cells)
  • D: Sclerenchyma
  • E: Cortex (parenchyma cells)
  • F: Sclerenchyma
  • G: Phloem
  • H: Xylem
  • I: Cambium
  • J: Sclerenchyma
  • K: Phloem
  • L: Xylem
  • M: Vascular bundle
  • N: Pith
  • O: Pith (parenchyma cells)
  • P: Cortex (parenchyma cells)

Final Answer:

The structures labeled A-P in the images of _Tradescantia pallida_ stem cross-sections are: A-Cuticle, B-Epidermis, C-Cortex (parenchyma), D-Sclerenchyma, E-Cortex (parenchyma), F-Sclerenchyma, G-Phloem, H-Xylem, I-Cambium, J-Sclerenchyma, K-Phloem, L-Xylem, M-Vascular bundle, N-Pith, O-Pith (parenchyma), P-Cortex (parenchyma).

A model rocket is launched with an initial upward velocity of 40 m/s. The rocket's height h (in meters) after t seconds is given by the following: h = 40t - 5t^2 Find all values of t for which the rocket's height is 15 meters. Round your answer(s) to the nearest hundredth. (If there is more than one answer, use the "or" button.) t = [] seconds

7) Format columns G - K as currency with no decimals. 8) Sort the table on Last Name (column D). 9) Change the table style to one you like. 10) In cell L22, create an IF formula that puts "NYC" in column L if column F is "New York", if not put "Other." Copy this formula to the remaining rows in column L. 11) Filter the table for any employee hired between 1/1/2013 and 12/31/2013. In Cell G40, type (do not use a formula) the results for count of employees. 12) Clear the filter. 13) Filter the table for any employee with a last name that begins with M. In cell G42, type (do not use a formula) the results for the total Annual Compensation. Clear the filter. 14) Insert a comment in cell H26 that includes your name and "This salary seems high." 15) Rename the tab (sheet name) to Payroll Data and change the tab color to Blue 16) Enter your name as a center header, save the file, and submit your file.
