Organic Molecules

Fats/lipids notice the amount of Hs to Os Notice the presence of C,H, and O and the complexity

Notice the presenc of N, C, and H.

Sugars also have C,H, and O in a 2 to 1 ratio

They can form chains and become large and complex

Define carbohydrates and list their functions.
The simplest carbohydrates are sugar monomers, the monosaccharides; be able to give examples and their functions.
A polysaccharide is a straight or branched chain of hundreds or thousands of sugar monomers, of the same or different kinds; be able to name common polysaccharides and state their function(s) in a cell.
Define lipids and list their functions.
Distinguish a saturated fat from an unsaturated fat.
Describe proteins and cite their general functions.

Graphs, yes sir!

Control vs experimental
I am looking for a good explanation of the independent and dependent variable. Check back
Got it !
Question: What's a variable?
Answer: A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables-independent and dependent.

Question: What's an independent variable?
Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.

Question: What's a dependent variable?
Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.
Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable:
(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).

For example:
(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).

Sylvester Welcome September 2007
Just wanted to begin the blog for our class. I wanted to welcome you to our class and start a blog where I can put important info.I am using the website atwww.regentsprep.orgThe first topic and questions to review are the ones related to living vs. nonliving thingsThere are practice questionsWhat are some similarities and differences between living and nonliving things?What are organic compounds? What is there antonym?How are fats, lipids, carbohydrates, proteins, amino acids, and DNA similar?How can viruses, chlorophyll, and mitochondria cause problems for categorizing?What does the acronym CHNOPS stand for?What is an acronym?What info could I get from typing in biology at the websites www.ask.com and www.about.com?How could I get in touch with Mr Sylvester? email is odontocete917@yahoo.comCan I start practicing for the test by taking questions for practice on this topic?
