Anyone know anything about the Biology CLEP Exam?

[spatts]

Yeah...I was thinking I should add: "Then I changed my course of study for 4 years, and ended up 4 years behind, yadda yadda yadda."

I would still be enrolled if I had the time and money. I love to learn. Especially in a small group setting. Particularly if the group is full of critical thinkers...those perspicacious few.

CLEP makes it faster and cheaper though.

This is off topic. but are you smart, or do you just study alot. I don't get it. Getting a B.S. in biochem & a B.S. in engineering at the same time.



Anyway warik, i'd recommend getting a syllabus from your biology class, the official study guide & learn the main ideas of the chapters. You should pass doing that.

Thats a good question.

I never really liked Bio-chem until i started training seriously.
After that, I just ate book after book.
When you have a passion for something, you just strive to
know more and more and more.....LOL

Study a lot? No, not really. But I do read a lot.

My mother tells me I'm lazy.......LOL

She's partly right. I coast in some classes using just my intelligence.

I need to learn to work hard.

[spatts]

That was my problem. I never had to crack a book. So when I got to the genetics school, and had to actually STUDY, I didn't know how. Got my arse put in its place by those "slow and steady wins the race" folks.

 

[Puc]

Warik if you think you have the clap you can get a test done at planned parenthood. you do not have to know anything about its biology. they have counselors to work with you on that.

1) which of the following is not part of th structure of the nucleus?


D) Centroles

-----------------------------------------------------------------------------------------2)Site Of Amino Acid addition to a polypeptite chain?

A) Ribosomes
-----------------------------------------------------------------------------------------3) Polar Covalent bonds, such as those in a water molecule occur whenever?

Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion). In a polar covalent bond, the bonding electrons will spend a greater amount of time around the atom that has the stronger affinity for electrons. A good example of a polar covalent bond is the hydrogen-oxygen bond in the water molecule.

Water molecules contain two hydrogen atoms (pictured in red) bonded to one oxygen atom (blue). Oxygen, with six valence electrons, needs two additional electrons to complete its valence shell. Each hydrogen contains one electron. Thus oxygen shares the electrons from two hydrogen atoms to complete its own valence shell, and in return shares two of its own electrons with each hydrogen, completing the H valence shells.

-----------------------------------------------------------------------------------------
4) Which of the following statements is correct concerning Enzyme-Catalyzed Reaction?


* Enzyme - Wikipedia, the free encyclopedia
* Enzyme catalysis - Wikipedia, the free encyclopedia
-----------------------------------------------------------------------------------------5) Which of the following is TRUE of the cytoskeleton in a typical animal cell?

http://en.wikipedia.org/wiki/Cytoskeleton

-----------------------------------------------------------------------------------------6) Which of the following treatments would be least likely to destroy the activity of an enzyme in a solution?

-----------------------------------------------------------------------------------------7) which of the following will function in packaging proteins for secretion?

E) Golgi Apparatas
-----------------------------------------------------------------------------------------8) In Muscle cells, Fermentation and aerobic respiration are similar in all the following aspects EXCEPT?
Muscle cells require oxygen.
Fermentation requires no oxygen.
Aerobic Respiration sometimes requires oxygen.
-----------------------------------------------------------------------------------------9) Red Blood cells, add water, cells swell and burst, why?
The red blood cells swell when placed in distilled water, because of osmosis.
There are no salts or any other molecules dissolved in the distilled water, but the red blood cell has many molecules dissolved in its cytoplasm.
Because Osmosis states that water tends to move toward regions where there is more solute, the distilled water moves into the red blood cell throughout the plasma membrane, and the cell gets bigger/swells. If this happens for too long, the red cells will actually burst (called Lysis) and die. The Hemoglobin (protein that binds to oxygen we breathe to deliver the oxygen to the cells in our body) in red blood cells is what makes them red, so when the lysed cells spill the hemoglobin out into the water, it turns pink.
-----------------------------------------------------------------------------------------
10) Cells of Higher plants and those of higher animals have which of the following in common?
They are eukaryotic and have a true nucleus with chromosomes and a nuclear envelope and which divides by mitosis.
-----------------------------------------------------------------------------------------
11) The primary structure of a protein is formed by?
Primary structure - the amino acid sequence of the peptide chains.
The primary structure is held together by covalent or peptide bonds, which are made during the process of protein biosynthesis or translation.
The sequence of the different amino acids is called the primary structure of the peptide or protein.
The primary structure of a protein is determined by the gene corresponding to the protein. A specific sequence of nucleotides in DNA is transcribed into mRNA, which is read by the ribosome in a process called translation. The sequence of a protein is unique to that protein, and defines the structure and function of the protein.
-----------------------------------------------------------------------------------------
12) Which of the following is true of the major component of plant cell walls?
Cellulose
-----------------------------------------------------------------------------------------
13) All of the following compounds contain nitrogen EXCEPT?
Glucose

-----------------------------------------------------------------------------------------
14) Which of the following are the required starting materials for the Calvin Cycle?
The starting materials for the Calvin cycle are carbon dioxide and a five-carbon molecule called RuBP.
The Calvin Cycle uses carbon atoms from carbon dioxide in the air, energy from ATP, and electrons and hydrogen atoms from NADPH to produce a series of organic molecules. Some of these organic molecules are used to make sugars and other substances needed for energy and growth. Other organic molecules return to the beginning of the cycle, enabling the capture of carbon dioxide to continue.
-----------------------------------------------------------------------------------------
15) In a eukaryotic cell, grana are found in which of the following organelles?
Chloroplasts also contain an extensive internal system of interconnected membrane-limited sacs called thylakoids, which are flattened to form disks; these often are grouped in stacks called grana and embedded in a matrix, the stroma.
-----------------------------------------------------------------------------------------
16) The metabolic reactions at the krebs cycle occur in the mitochondria in which of the following?
Humans, Mammals, and Animals.
-----------------------------------------------------------------------------------------
17) Ribosomes are composed of?
Ribosomes are composed of RNA and protein. A ribosome is a large molecular complex (organelle), composed of several proteins and ribonucleic acid that reads messenger RNA and thereby synthesizes proteins. Ribosomes are composed of one or two very large rRNA molecules and many smaller protein molecules. The smaller proteins probably act as building blocks to create polypeptides using the rRNA as a scaffold.

[miscreant]

Here's the secret to a CLEP.

1) Find out how many answers you need to get right to pass. This is usually in the 40-46 range.

2) Start the test. Go through the test and answer every question you KNOW is right. Mark these off with an A by the question when you answer it.

2) Now go through the test and answer any questions that may have their answers in the question of another question:
for instance, you may find a question that says "In what year did Bob discover Fred?", then several questions later, the question is "When Bob discovered Fred in 1975, what was the result"...Get the point. You have to go through the test once to see if this happens.

3) Now count up how many questions you have answered RIGHT so far (at this point, you have many questions unanswered). If it is sufficiently greater than the required score, then stop - you are done.

Why?

Because you are DINGED 1/4 point for every wrong answer. The key to CLEPing is to NOT just answer all the questions, but only answer enough to pass, because wrong answers count AGAINST you.

4) If you have not answered a confortable amount above the required, then go through the test and find the ones you have the best chance of getting right - one's you can eliminate down to a 50/50 chance, and answer enough of those to get you decently past the required passing number.

Good luck!

Miscreant, that's a very good strategy. No doubt that could work very well on other exams too. Just reading all the questions first, if you have time, could really provide the direction you want to go in which questions that you answer first.

I bet you did really well on the CLEP when you did it with the strategy that you had because it's very smart.

 

[Luepert]

I just finished my freshman year of high school. I had biology as a core class so I decided to try the clep. My only preparation was reading through my own notes once and I got a 62. 6 credits! SCORE!

But anyways that's just me, I would recommend actually studying a lot like I did during the actual school year.
