select any five bones in the body and provide the following for each:

  • A locational description using proper regional AND directional terminology
  • An identification of a synovial joint this bone is a part of and a description of any features of that bone that are associated with the identified joint
  • A description of the movement that is possible at the identified joint

(e.g. – The occipital bone of the skull is found in the posterior, inferior portion of the cranial cavity. It articulates with the atlas at the atlanto occipital joint. The occipital condyles of the occipital bone articulate with the superior articular facets of the atlas (or C1 vertebra). The atlanto occipital joint consists of two condyloid (or ellipsoid) synovial joints, allowing flexion and extension and a small amount of lateral flexion.)

W71) I am study Excel Functions. Please answer in detail using Excel functions.

Parking Tickets – The Chicago police department claims that it issues an average of only 60 parking tickets per day. The data below, reproduced in your Excel answer workbook, show the number of parking tickets issued each day for a randomly selected period of 30 days. Assume σ =13.42.   State the null and alternate hypotheses, as well as the claim, which (hint!) is in the null hypothesis. Is there enough evidence to reject the group’s claim at α = .05?   (As with all of these exercises, use the P-value method, rounding to 4 digits.) (Hint: so since we know the population standard deviation, use the standard normal distribution z-test .) (Monday class)

                                                            Digital Clock with LCD Display

write the code for the function header:

#include "mbed.h"

#include "TextLCD.h"

     

1. In this lab, you will redo a digital clock this time with the LCD display and in the format of HH:MM:SS (HH is the hour from 0 -- 23, and MM is the minute from 00 -- 59, and SS is the second from 00-59)

2. Design the circuit that properly connects the LCD display to the mbed platform. Include your connection diagram in the Experiment Results of your lab report.

3. Based on the hardware design from step 2, design your code to implement the digital clock. Upon reset of the board, the clock should reset to 00:00:00, then changed to 00:00:01 after 1 second, and 00:00:02 after another second, etc.

4. Test your digital clock with an accurate clock (e.g. the clock in the computer). Explain the test process and what you observe while carrying out the test process. Is your digital clock accurate? If it is not, explain what you think might be the cause of the inaccuracy. "Calibrate" your digital clock by modifying your code to be as close to the accurate clock as possible. Include the details of your calibration process in your lab report.

I am more interested in the coding. Thanks

(b) Under the steady-state, how many of the 50,000 in the labor force are employed and how many are employed each month? How many of the unemployed become employed each month?

(c) Suppose p = 0.08 and q = 0.32. What is the steady-state unemployment rate and how many workers move from employment to unemployment each month?

Two structures of alanine can be drawn that have a net charge of zero, but the predominant form of alanine at its pI is zwitterionic. Why is alanine predominantly zwitterionic rather than completely uncharged at its pI? What percent (to one significant figure) of alanine molecules would be in the completely uncharged form at the pI? Hint: pK1 of alanine is 2.35 and pK2 is 9.87.
