SAT Subject Test: Biology

Subjects : sat, science, biology
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.

14. Describes cells that have a double set of chromosomes in homologous pairs (2n)






15. The creation of certain strains of specific traits through control of breeding






16. The law by which genes on different chromosomes are inherited independently of each other






17. An animal with a constant body temperature






18. A nitrogen base such as cytosine - thymine and uracil; when joined with sugar or phosphate - a component of nucleotides and nucleic acids
