- 7. the long-term absence from the diet of one or more essential nutrients
- 8. eats other animals (meat)
- 11. gets rid of nitrogenous metabolites and other waste products
- 12. regulate solute movement between internal fluids and the external environment
- 13. composed of carbon atoms attached to other atoms, such as hydrogen, oxygen and nitrogen
- 14. specialized epithelial cells that regulate solute movement
- 17. eat mainly autotrophs (plants)
- 18. adding toxins and other solutes from the body fluids to the filtrate
Down
- 1. regulates solute concentrations and balances the gain and the loss of water
- 2. expend energy to control water uptake in a hypoosmotic environment and loss in a hyperosmotic environment
- 4. are isoosmotic with their surroundings and do not regulate their osmolarity
- 5. the act of eating
- 6. the solute concentration of a solution, determines the movement of water across a selectively permeable membrane
- 9. reclaiming valuable solutes
- 10. a nutrient that is needed in small amounts to keep the body healthy
- 15. the source of energy for use and storage at the cellular level
- 16. regularly consumes other animals along with plants as well
