BIO 168 TEST #1 QUESTIONS &
ANSWERS(RATED A+)
Anatomy - ANSWERScience of structure (morophology)
Cytology - ANSWERStudy of cells
Histology - ANSWERStudy of tissues
Physiology - ANSWERScience of function
Characteristics - ANSWEROf living organisms (movement. Growth, reproduction,
excretion, respond to stimuli)
Metabolism - ANSWERAll the chemical reactions of living organisms
Two types of metabolism - ANSWERAnabolism and catabolism
Anabolism - ANSWERAssembling compounds and storing energy
Catabolism - ANSWERbreaking compounds down and releasing energy
Homostasis - ANSWERmaintaining a constant internal environment
Non-living - ANSWERatoms-compounds-molecules-organelles
Living - ANSWERcells-tissues-organs-system orgnisms
Integumentary - ANSWERComponents: hair,skin,nails
Functions: Protection, Sensation, Temperature Regulation, Barrier of pathogens
Atomic mass - ANSWERnumber of protons + neutrons (in nucleus) stable atoms
have no net charge (# protons = # electrons) unstable atoms - have a tendency to
revert back to stable atom
Ions - ANSWERincrease or decrease in # of electrons of stable atom
Increase results in a negative charge (Cl-)
Decrease results in a positive charge (Na+)
Isotopes - ANSWERincrease or decrease in number of neutrons changes mass but
not charge (some are radioactive) atomic bonds
Skeletal - ANSWERComponents: Axial &Appendicular
Functions: support, protection, movement, blood cell production
Muscular - ANSWERComponents: Skeletal, smooth & cardiac
Functions: movement, heat, blood circulation
, Nervous - ANSWERComponents: central & peripheral
Functions: communication, memory
Endocrine - ANSWERComponents: Glands & Hormones
Functions: Regulate Body Functions
Cardiovascular - ANSWERComponents: Heart & Blood Vessels
Functions: Body transport system
Lymph - ANSWERComponents: Lymph glands and vessels
Functions: Immune response, garbage collector
Digestion - ANSWERComponents: Mouth, stomach, small & large intestine
Functions: Breakdown and absorb nutrients rid solid waste
Respiratory - ANSWERComponents: nose, trachea, & lungs
Functions: Exchange CO2 & O2
Urinary - ANSWERComponents: Kidneys & Bladder
Functions: Rid liquid waste regulate blood chemistry
Male Reproductive - ANSWERComponents: Testes & penis
Functions: Procreation & Recreation
Female Reproductive - ANSWERComponents: Ovaries & Uterus
Function: Procreation & Recreation
Metric Equalivents - ANSWERin a water environment 1 ml = 1cc = 1 gm
Atoms - ANSWERsmallest unit of an element
Protons - ANSWERpositive charge, mass of 1
Neutrons - ANSWERno charge, mass of 1
Electrons - ANSWERnegative charge, mass of 0
Atomic number - ANSWERnumber of protons
Ionic - ANSWERatoms combine and gain or lose electrons (very strong bonds) one
atom gains electrons (-), one looses electrons (+)
Covalent bonds - ANSWERatoms combine and share electrons (very strong bonds)
Polar covalent bonds have a slight charge (water)
Nonpolar covalent bonds have a slight charge (methane)
Hydrogen bonds - ANSWERhold molecules together (weaker bonds) Water, protein,
& DNA molecules all held together with H bonds
