...Worksheet2- Brittani Wright
1. a) Define a cell. A cell is the basic unit of life b) What is a unicellular organism? An organism that consists of only one cell c) Can a cell be multicellular? No because a cell is the smallest unit of life, cells can however join together to start forming something else
2. a) What is a difference between prokaryotic and eukaryotic cells? b) What is one significant similarity? Prokaryotic cells do not have a neucleus and Eukaryotic cells do have a nucleus. One similarity is that both are covered by a cell membrane and contain RNA as well as require energy
3. Which type of microscopy provides a 3d view of the surface of an object? Scanning electron microscope
4. Would you find proteins inside cells or cells inside proteins? (Choose one answer.) Protein inside cells
5. Which type of molecule travels through an aquaporin? Small, lipid-soluble molecules
6. Explain the basic organization (main components) of a plasma membrane. Include at least 4 distinct parts in your description. A plasma membrane is composed of a phospholipid bilayer in which proteins are embedded. The hydrophilic heads of phospholipids are a part of the outside surface and the inside surface of the membrance. The hydrophobic tails make up the interior of the membrane. The plasma membrane is asymmetrical. Carbohydrate chains are attached to the outside surface, and cytoskeleton filaments are attached to the...

(Polynomials)
Key Concepts
Constants : A symbol having a fixed numerical value is called a constant.
Example : 7, 3, -2, 3/7, etc. are all constants.
Variables : A symbol which may be assigned different numerical values is known as
variable.
Example :
C - circumference of circle
r - radius of circle
Where 2 &
are constants. while C and r are variable
Algebraic expressions : A combination of constants and variables. Connected by
some or all of the operations +, -, X and
Example :
is known as algebraic expression.
etc.
Terms : The several parts of an algebraic expression separated by '+' or '-' operations
are called the terms of the expression.
Example :

Degree of a polynomial in one variable : In case of a polynomial in one variable the
highest power of the variable is called the degree of the polynomial.

NCTM Addenda Series/Grades 9-12
The Park and Planning Commission decided to consider three factors when attempting to improve the daily profits at their sports facility:
❖ The number of all-day admission tickets sold
❖ The cost of operating the facility
❖ The price of each all-day admission ticket
After carefully analyzing their operating costs, they found that it would be impossible to cut them further.
Daily Operating Costs
Advertisements $ 55.00
Employees’ pay 310.00
Heat, lights, taxes, food, rent 435.00
Knowing that the maximum number of potential patrons is 200, the Park and Planning Commission decided to vary the price of each admission ticket to see what effect this change might have on the number of tickets sold. After much experimentation, they collected the following sales data:
Ticket Price [in $] Average Number of Tickets Sold

SCI 241 Nutritional Study Worksheet
Resource: University of Phoenix Library and the Internet
Select one of the following topics to research:
Coffee or caffeine
Eggs
Low-fat diets
Low-carb diets
Other nutrition topic approved by your instructor
Research your topic using 2 nutrition articles that discuss your topic, but provide opposing viewpoints. Use the Internet, the University Library, or the search links provided in the Week 2 Electronic Reserve Readings to locate the articles.
Write 50- to 200-word responses to each of the following questions based your findings. Use your own words and provide examples to support your answers.
1. What topic did you choose? Discuss the position of each of the two articles you selected.
I choose eggs for this assignment. Each artlice talks about different nutritional value of eggs. For example one article focuses on how eggs can affect a persons hunger and in return help them maintain a healthy calorie count which can help them to maintain a healthier weight. The second article focused on how eggs are with cholesterol.
2. What health claims are stated in the articles, such as drinking coffee every day will lower one’s risk for cancer?
The first article I read talked about eggs helping you control a hunger. They claimed that eggs are healthier alternative to control your hunger. They did a study on a group od obese...
