BIO 253 HONDROS DEFINATIONS
WITH CORRECT MEANINGS
structure - Answer- determines function
young adulthood - Answer- the period of greatest homeostatic efficiency
developmental stages - Answer- early years
aging process - Answer- late years
homeostasis - Answer- temperature, blood carbon dioxide, blood glucose regulations
feedback loops - Answer- control or restore homestasis by self regulation
negative feedback control - Answer- opposite of the change, more common than
positive fb, inhibitory, maintains homeostasis
positive feedback control - Answer- stimulatory, amplifies or reinforces the change,
disrupts homeostasis, swift completion of functions, - LABOR- BLOOD CLOTTING
Ions - Answer- atoms or groups of atoms with electical charges
cation (+) - Answer- posi-+-ive charge ion (+)
anion - Answer- negative charged ion (an = neg)
electrolytes - Answer- compounds with ionic bonds
chemical bonds- - Answer- forces that hold atoms or molecules together- number of
electrons in outermost shell determines bonding
ionic bonding - Answer- gain and lose electrons, solid state, NaCl- found in teeth and
bones- give strength and structure, conduct electricity in solutions ( electrolytes)
Covalent bonds - Answer- 2 or more atoms sharing electrons, most common bond, can
be single, double or triple bonds
hydrogen bonds - Answer- weakest, found in water, no sharing of electrons, partial
positive attracts part neg. charge
Catabolism - Answer- decomposition reactions- hydrolysis
