organ
organ system organism
3. what are the characteristics of life? ✓✓ Correct answer movement
responsiveness
respiration absorption
secretion digestion
assimilation- changing of absorbed substances into chemically ditterent forms circulation

5. define homeostasis ✓✓ Correct answer maintaining of a stable enviroment
6. what is a homeostatic mechanism ✓✓ Correct answer monitors aspects of internal environment and corrects as needed
*negative feedback mechanism
7. define matter ✓✓ Correct answer anything that takes up space and has mass
, 8. element ✓✓ Correct answer composed of chemically identical atoms
9. atom ✓✓ Correct answer smallest particle of atom, basic unit of matter
10. what are structure of an atom ✓✓ Correct answer
nucleus protons
neutron electrons
11. define nucleus, proton, electron, neutron ✓✓ Correct answer nucleus- central part of atom
proton- positive charge electron-
negative charge neutron- no electrical
charge
12. ionic bond ✓✓ Correct answer formed when electrons are transferred from one atom to another
