Glucocorticoid secretion increases in response to stress. Which of the following
hormones will cause the adrenal gland to release glucocorticoids?
Growth hormone (GH)
adrenaline
Anti-diuretic hormone (ADH)

During labor, the baby's head pushes against the mother's cervix causing nerve
impulses to transmitted to the brain to stimulate release of oxytocin from the
pituitary gland into the blood stream. Increased levels of oxytocin in the blood
stream stimulate uterine contractions which results in the baby's head pushing
against the mother's cervix. The process repeats causing more and more
oxytocin to be released into the blood stream stimulating stronger and more
frequent contractions.
Is this an example of negative feedback?
a.Yes
b.No

Which of the following accurately describes the typical transmission of an
electrical signal through a neuron?
a.cell body>dendrite>axon
b.axon>dendrite>cell body
c.axon>cell body>dendrite
d.dendrite>cell body>axon

Which of the following is defined as a small gap between transmitting and
receiving neurons?
a.cell body
b.axon
c.synaptic terminal
d.synaptic cleft

Fill in the blanks with the correct word(s).

In the central nervous system (CNS), neurons bundled together are called Blank 1.[ ]
. In the peripheral nervous system (PNS), neurons bundled together are
called Blank 2 [.]

When you performed the "ruler catching" experiment, which of the following
accurately describes the muscles used to catch the ruler?
a.sensory receptors
b.integration centers in the brain
c.effector cells

When a response "skips" the integration process where the brain makes a decision about
how to respond to a stimulus, how would we describe this action by the nervous system? In
other words, if a response to a stimulus is made involuntary without conscious thought,
how would the relay system used by the nervous system be described?
a.neural integration

The management estimates total sales for the period January, 2019 through June, 2019 based on actual sales from the immediate past six months. The following assumptions are made:  The Sales were $140,000 in July 2018 and then the sales grew by 2% each month in the first three months (i.e., from August to October 2018) and by 5% in the next two months (i.e., in November and December 2018). The sales are expected to grow by 1% each month thereafter.  35% of the Sales are collected in the same month. 33% of the sales are collected in the following month. 31% of the sales are collected after two months and the remainder are not collected.  The Purchases are 70% of each month’s sales and paid in the same month.  Wages and Salaries are $25,000 each month and paid in the same month.  Other administrative expenses are $15,000 and paid in the same month.  Depreciation expense is $5,000 each month.  An electrical device worth $30,000 will be purchased in April 2019. 50% of the amount due will be paid immediately and the balance will be paid in May, 2019.  The company had previously taken a loan of $125,000. The annual interest rate on the loan amount is 5%. The interest is paid twice a year in June and December each year. Assume that no principal repayments are made in this period, only interest payments are made.  The company pays rent of $3,500 quarterly (in March, June, September, and December each year).

Questions: 1. Determine the total cash inflows, the total cash outflows, and the expected change in cash for each month from January to July, 2019. Show your work in excel using excel functions. Based the findings, explain in your own words whether the company should borrow/invest and how much and in which months. [4.50 points]

2. Describe in your own words some of the short-term borrowing options that the company may adopt. Please write your answer in another tab on the same excel file, no need to upload another Word Document file or type your answer elsewhere. [0.50 points]

Write the class Complex that supports the basic complex number operations. Such operations are addition (+), subtraction (-) and multiplication (*) of complex numbers, and multiplication (*) of a complex by a scalar (float or int). All methods must return (not print) the result. Class also supports the rich comparison for equality (= =)

• - Check the doctest for object behavior examples.

• - You must use the special methods for those 4 operators in order to override their behavior

• - You will need other special methods to achieve a legible object representation.

• - Multiplication by scalar and by another complex number use the same operator, so you must check the type of the object in order to decide which operation you have to perform

• - Rich comparison returns a Boolean value

• - The rest of the methods must return a new Complex object, this means the original

  objects should not change after the operation is performed.

• - Test your code, this is how you ensure you get the most credit out of your work!!

• - When returning error messages, make sure your string contains the word ‘error’

• - You are not allowed to modify the constructor or any given code.

• - Hint: Section 3.3.1. Basic customization (__eq__) and Full Section 3.3.8. Emulating numeric types inhttps://docs.python.org/3/reference/datamodel.html#emulating-numeric-types

  Write the property method conjugate into the Complex class. The complex conjugate of the complex number z = x + yi is given by x – yi

Remember, you are not allowed to modify the given constructor. The method conjugate must be a property method, otherwise, no credit will be given. Property methods are discussed in the video lectures!

Starting Code:

--In the GSS, the original race variable was coded as: whites=1, blacks=2, others=3. Which of the following possibilities is the best way to recode this variable into a dichotomy with “white” as the reference category?

a.) whites=1, non-whites=2

b.) non-whites=1, whites=2

c.) whites=0, non-whites=1

d.) whites=-1, non-whites=+1

-- Another word for the reference group is:

a.) the omitted variable

Emilio (DSM-IV Casebook, p. 189-190)

Emilio is a 40-year-old man who looks 10 years younger. He is brought to the hospital, his twelfth hospitalisation, by his mother because she is afraid of him. He is dressed in a ragged overcoat, bedroom slippers, and a baseball cap, and wears several medals around his neck. His affect ranges from anger at his mother ("She feeds me sh*t . . . what comes out of other people's rectums") to a giggling, obsequious seductiveness toward the interviewer. His speech and manner have a childlike quality, and he walks with a mincing step and exaggerated hip movements. His mother reports that he stopped taking his medication about a month ago, and has since begun to hear voices and to look and act more bizarrely. When asked what he has been doing, he says "Eating wires and lighting fires." His spontaneous speech is often incoherent and marked by frequent rhyming and clang associations (speech in which sounds, rather than meaningful relationships, govern word choice).

Emilio's first hospitalisation occurred after he dropped out of school at age 16, and since that time he has never been able to attend school or hold a job. He has been treated with medication during his hospitalizations, but doesn't continue to take medication when he leaves, so he quickly becomes disorganised again. He lives with his elderly mother, but sometimes disappears for several months at a time, and is eventually picked up by the police as he wanders in the streets. There is no known history of drug or alcohol abuse.

QUESTION ON OFFER & ACCEPTANCE

Linda has decided to sell her car and parks it outside her house with a notice on the front windscreen stating: “For sale; pristine condition; one owner; £4,750 or near offer. Please call at 1 Farmers Road or Telephone 0201-123456. First person to agree on a price will get the car”.

On Monday at 9.00am, Eunice sees the car, but as she was running late for a dental appointment, she telephones Princess from work at 10.00am, and makes an offer of £4,500, which Linda says she would like to consider.

Eunice says that she will assume Linda has accepted her offer unless she hears from her by 9.00pm that evening, a proposal to which Linda agrees.

At 11.00am on Monday, Daniel calls at Linda’s house, but Esther, Linda’s daughter, was the only person at home. He therefore leaves a note reading; “Monday 11.00am. Please keep the car for me. Here is a cheque for £4,750, Daniel”. Maxwell leaves the cheque together with the note on a desk in Linda’s study.

At 12.15pm on that same Monday, Mark passes by the car and sees the notice, and within a few minutes, posts a first class letter of acceptance together with a cheque for £4,750, using the post box at the end of the street. Unfortunately, Mark misaddresses his letter, so it arrives on Friday.

At 3.00pm on Monday, Linda decides to accept Eunice’s offer and posts a letter of acceptance to Eunice’s business address, saying: “I agree to sell on your terms. Because of the lower price, can you pay in cash”?

At 9.30pm on Monday, Linda reads Daniel’ acceptance and immediately telephones Eunice’s business address, leaving a message on the telephone service answering machine: “Ignore the letter you will receive, deal off, Linda”. Eunice is away on business and only listens to the tape on Wednesday evening.

Please help me answer this question.

Linux Fundamentals part 3

Below are questions related to the command line use of Linux.  You can use the videos, man pages, and notes to answer these questions. 

Remember that Linux is CASE SENSITIVE.  Rm and rm are NOT the same command.  I will count off totally for a question if you do not take this into account.

For each command give me the ENTIRE COMMAND SEQUENCE.  If I ask you  'What command would I use to move the file one.txt to the parent directory and rename it to two.txt?", the answer is NOT 'mv'. That is only part of the command. I want the entire command sequence.

10. Find all files under the current directory with an accessed time was more than 2 days ago.

11. I have a file called 'BackupLogs.tar.bz2' in my home directory (because you made it from Questions 4 and 8, right? Right!). I want to uncompress and unarchive the files in it. What single command would I use?

12. I have a file called BackupLogs.tar.bz2 and I want to uncompress and ONLY uncompress the file (NOT uncompress and unarchive). What command would I use?

13. I want to search for all files in the directory ~/Documents which contain the keyword "add", case sensitive, and as the whole word only. Words like addendum, addition, etc, should not be found in the results; just 'add'. Additionally, I only want to see the name(s) of the file(s) that have matches as a result of running the command. This means your result should show not the keyword hit AND surrounding text, but rather suppress that output and instead display just the file name. What command would I use? This may sound complicated, but break down each step and use the man page.

14. I have a large file named walloftext.txt and I want to view only the first 5 lines of the file. What command would I use?

15. Same as file as Question 14, but I want to view only the last 7 lines.
