CSET Subject 2: Science

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. Is the smallest unit of an element that still has the properties of that element.






2. Because carbon bonds readily with a variety of different elements and compounds - making possible the great chemical complexity necessary for life.






3. A bond formed when atoms share one or more of their valence electrons.






4. Force = Mass X Acceleration






5. Radioactively decay back into their 'normal' forms over time






6. 1. producer 2. primary consumer 3. secondary consumer 4. tertiary consumer 5. decomposer

12. Phase where spindle grows and which cuts the cell






13. 1. inner core 2. outer core 3. mantle 4. crust






14. Within compounds - the various atoms making up molecules are held together by...






15. A group of subjects upon which a hypothesis is tested.






16. A group which resembles the experimental group in all other ways - but on which the hypothesis is not tested. In some clinical trials the control group is given a placebo.






17. 1. convergent 2. divergent 3. transform






18. 1. the more massive either or both bodies are - the greater the gravitational force between them. 2. the further apart two bodies are - the lesser the gravitational force between them.

33. When the Moon or the Sun are pulling at perpendicular angles we get less extreme tides.






34. An atom with an imbalanced charge






35. Has a pair of chromosomes






36. Thin - flexible barrier around a cell; regulates what enters and leaves the cell
