In vertebrates, what fills the space between cells which allows for the movement of material into and out of cells?
Interstitial fluid.
What tissue covers the outside of the body and lines the organs and cavities within the body?
Epithelial tissue
What tissue binds and supports other tissues?
Connective tissues
What tissue senses stimuli and transmits signals throughout the animal?
Nervous tissue
Regulator vs conformer
Regulator uses internal control mechanisms to moderate internal change, while conformer allows its internal conditions to vary based on external changes.
Endothermic vs exothermic animals.
Endothermic animals generate heat by metabolism, exothermic animals gain heat from external sources
True or false, some animals can regulate body temperature by adjusting their rate of metabolic heat production
True
______ regulates solute concentrations and balances the gain and loss of water
Osmoregulation
Most animals are _____, they cannot tolerate substantial changes in external molarity
Stenohaline
What type of animals can survive large fluctuations in external osmolairty
Euryhaline

ATP
How many amino acids and how many vitamins are there essential to humans?
20 amino acids, 13 vitamins
Do cnidarians have a body wall that is only two cells thick and encloses a gastrovascular system?
Yes. True
What three basic components do both open and closed cardiovascular systems have?
Circulatory fluid, set of tubes, a muscular pump.
What is unique to closed circulatory systems?
Blood is confined to vessels and distinct from interstitial fluid.
