CSET Science Vocab 2

Subjects : cset, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. This primary component of chromosomes carries an organisms genetic code.






2. The tissues aquatic animals use to breath in water.






3. Cell division consisting of prophase - metaphase - anaphase - and telophase - that usually creats in two new nuclei - each with a full set of chromosomes.






4. A cell with two copies of each chromosome.






5. Plants that live through more than one growing season.






6. A disease related to lower levels of insulin.






7. An organism's unique place in the environment.






8. A process through which organisms make nutrients available to cells.
