...Unit 5: P1 Main functions of the cell membrane The cell membrane is the outer cover for a cell, and something that lets things out and into the cell. The function is to protect the interior of the cell by allowing some substances into the cell, and also blocking some substances from coming in. Main functions of the nucleus The nucleus is the centre of the cell which controls things. Nuclei contains genetic material e.g. DNA and also controls the cells growth and reproduction. In red blood cells, the nucleus is lost during development and is the only cell that is able to survive without a nucleus. The nucleus contains information that is transferred to the next generation. Main functions of the cytoplasm Cytoplasm is the material inside of the cell, generally clear and jelly like that fills the inside of cells. This is where the chemical reactions take place and where the fluid is able to flow slowly. The cytoplasm supports the cell and allows organelles to freely move throughout the cell. Glycogen and melanin are the chemicals that are the basic living materials that a cell needs, they also are responsible for skin and hair colour. Main functions of the mitochondria The mitochondria generates the energy to power the cell through respiration. Mitochondria: [pic] The mitochondria is the powerhouse of the cell it provides energy to the cell through respiration.The food that we eat is broken into simpler molecules like carbohydrates, fats and etc in our bodies.

...shalom kpogho What is Accounting? Accounting is the process of keeping financial accounts in check and stored in records for future references. Every business have to keep in check of their accounting data so that they know how much they have spent. How much goes in and how much goes out. There are many ways businesses keep record of data in the business by using a cash flow sheet, profit and loss account and a balance sheet. All these ways of keeping the business updated about the money they use, lose and make helps them for the future will let them know what to avoid or what to do again in order for that certain thing to happen again. Recording transactions Recording transactions of a business is to keep record of how much is being spent or how much is being sent to the company. Many keep record of this in a journal or documented so they have history of previous transactions made by the business. For example HM customs and revenue keep monthly transactions made by the public so they keep it as a data in their system of people who have made transactions with them. Annual and property transactions are also kept in a database with HM so they have all the transactions of the UK. Monitoring activity Monitoring activity of a business is key as you need to keep an eye on what the business is doing for example what transactions are being made and what money is being taken out or being put into the business and what the money is being spent on.

...ANATOMY AND PHYSIOLOGY P2, P3 4/27/2015 Khadra Ali | P1 – Outline the functions of the main cell components The human body is made up of millions of tiny cells that can only be seen under a microscope, cell also vary in shape and size. Cells are the basic structural of all living things. The human body is poised of trillions of cells. They give structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of them. Cells all have different sizes, shapes, and jobs to do. Each cell has a different function. The actual definition of cells is the smallest structural unit of the body that is capable of independent functioning, it consisting of one or more nuclei; it has a cytoplasm, and various organelles which are all surrounded by a cell membrane. There are four main parts to a cell; Plasma/Cell membrane, Cytoplasm, Nucleus and Cell Organelles. Plasma/Cell membrane: The plasma/cell membrane is a phospho-lipid-protein bi-layer; the lipids are small fatty molecules in two layers (bi-layer) with larger protein molecules inserted at intervals partly or completely through the bi-layer. The lipid molecules are phospholipids, the two lipid chains are insoluble in water and the phosphate head is water soluble. The fluid which surrounds the cells and the cytoplasm are watery environments next to the phosphate heads. Protein molecules create channels...

...Additional information Please demonstrate why you believe you are suitable for the post you are applying for. Being a sub warden I believe the duties of a sub warden would entail dealing with noise complaints, admitting locked out students or new arrivals to their rooms, providing support at social events organized by Claredale staff e.g. open days. Being an out of hours point of call for information and assisting students with finding the information they seek. Perform locking and opening duties at the required times e.g. opening the laundrette. I believe I would assist in fire drills and act as a link between residents and residence staff. I’m also aware that upholding the rules of Claredale house, could entail breaking up unauthorised parties and writing reports to hand in to residence staff. Past experience I’ve had experience being the liaison between students and members of staff. At Redhill Academy, I was house captain. We conducted team meetings to discuss how to improve the school experience. The goal was to get a range of students involved in activities, to promote a positive environment. Whilst walking around the school, students would come up with ideas and it would be our job to relay these suggestions to members of staff; form tutors or the head of house. Part of being house captain was ensuring we were positive role models for the rest of the school, this meant adhering to school rules at all times. I would adopt this attitude with the rules at Claredale. Wetherspoons...

... Quantity Conversely, a change in quantity demanded occurs as a response by consumers to a change in a commodity price. It is referred to as a movement along a demand curve (Frank, Ben and Louis 76). In the graph below, the initial price is P0 and the corresponding quantity demanded is Q0, however, when the price changes to P1, quantity demanded also changes to Q1. This represents a change in quantity demanded from Q0 to Q1. P D0 P1 B P0 A D0 Q1 Q0 Quantity A change in quantity supplied is caused by a change in the price of the commodity itself. It is referred to as a movement along a supply curve. Initially the price of a commodity is P1 but a fall in price to P2 leads to a fall in the amount of quantity demanded from Q1 to Q2.

...Chapter 6: CPU Scheduling • • • Basic Concepts Scheduling Criteria Scheduling Algorithms Operating System Concepts 6.1 Basic Concepts • Maximum CPU utilization obtained with multiprogramming. • CPU–I/O Burst Cycle – Process execution consists of a cycle of CPU execution and I/O wait. – Example: Alternating Sequence of CPU And I/O Bursts – In an I/O – bound program would have many very short CPU bursts. – In a CPU – bound program would have a few very long CPU bursts. Operating System Concepts 6.2 1 CPU Scheduler • The CPU scheduler (short-term scheduler) selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them. • A ready queue may be implemented as a FIFO queue, priority queue, a tree, or an unordered linked list. • CPU scheduling decisions may take place when a process: 1. Switches from running to waiting state (ex., I/O request). 2. Switches from running to ready state (ex., Interrupts occur). 3. Switches from waiting to ready state (ex., Completion of I/O). 4. Terminates. • Scheduling under 1 and 4 is nonpreemptive; otherwise is called preemptive. • Under nonpreemptive scheduling, once the CPU has been allocated to a process, the process keeps the CPU until it releases the CPU either by terminating or by switching to the waiting state. Operating System Concepts 6.3 Dispatcher • Dispatcher module gives control of the CPU to the process selected by the short-term scheduler;...

...is lower than that of its trading partner. 1.1 Technology and markets The Ricardian model assumes that production uses only 1 input (labor), with constant returns to scale. This assumption means that the technology in each country and each sector is entirely determined by the labor requirement per unit of output. The other assumptions are that (a) labor moves freely between sectors within a country, but (b) labor cannot move between countries. Assumption (a) implies that in a particular country, the wage must be the same in both sectors; assumption (b) means that the wage need not be the same (and typically is not the same) in the two countries. In addition, all agents are price takers, i.e. there is perfect competition. In my example, the unit labor requirements are unit labor requirement Corn (good 1) US Canada au = 1 1 Umbrellas (good 2) au = 1 2 ac = 3 ac = 6 1 2 Table 1, Labor requirements 1 (Corn is good 1, umbrellas are good 2.

...CHAPTER 15 Problem 1 Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 24 customers per hour or 0.4 customers per minute. a) What is the mean or expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period.
