Take a quick CLEP sample test with our FREE CLEP practice sample questions! These are a quick preview of what kind of information you'll be studying in our CLEP Study Guide for this subject. You can also use these CLEP sample test questions to gauge how ready you are to take your CLEP test. How do you know when you are ready? A good way to tell is when you can flip open our CLEP study guide, put your finger on a page, any page, and be able to define and explain what it is you're pointing out. That takes effort. Studying for a CLEP test does take effort, but based on your previous and current experience, there may be CLEP tests that you can take with little or no study. Taking a practice CLEP test can tell you if you are ready, it can give you an idea of the content of the CLEP test, it can tell you how difficult or easy your CLEP test will be.

CLEP Practice Test Answer Key:
- A:) Karl Lohmann.
- D:) Inverse proportion relation.
- A:) Cell volume and cell surface area ratio.
- C:) Anther. Pollen is found in the anther, where it is formed in pollen sacs.
- A:) Calvin cycle. This reaction takes place in the stroma of photosynthetic plants. The Calvin cycle is a part of photosynthesis, however, it isn’t the entire process.
- D:) Krebs cycle. The Krebs cycle is important to metabolism because it is how the body breaks down carbohydrates to produce energy.
- B:) T-C-G-G-A-T. This can be determined because adenine always pairs with thymine and guanine always pairs with cytosine.
- B:) Non-reducing sugar.
- B:) ot-1, 4 linkage.
- E:) Phylogeny. The study of phylogenics includes the study of different primitive characteristics and derived characteristics to determine line of descent.
