list chracteristics of life
drama cher glcr m(3)
digestion-
catabolic reaction
reprodution-
sexual, asexual, a=not without
absorption-
movement from digestive tract to circulatory system
movement-
gross, microscopic, trophisms, cyclosis
assimilation-
synthiesis of food )nutrients)
circulation
''
homeostasis
goover negative feedback responses
excretion
ridding the body of metabolic wastes
respiration

growth-
mst include synthesis
life spaon-
conception, growth , maturity, delcine, death
cells-
nuclues, cytoplasm, semipermeable membrane
reponsiveness
irritablity- the ability to respond to a stimulus
metabolism-
anabolism, catabolis go over
envio. needs for organisms:
water, food, oxygen, heat, pressure
water-
most abundatnt sub. in the body @ 60, needed for chemical reactions, transport medium, aids in the control of body temp.
food-
ant. substance that provides nutriends...pica
oxygen
needed to release energy stored in foods
heat
helps regulate metabolic reations
pressure
atmospheric pressure for breathing, hydrostatic pressure for blood flow
list sys.
is men clud rr
integumentary-
protects tissue, reg. body temp
skeletal
framework, produce blood cells, stores in. salt
muscular
movement, body heat, posture
nervous
sensory, detects change
endoctrine-
metabolic activities
cardiovascualr
movement of blood, sub. transport
lymphatic
defends agains infection
digestive
recieve, break down , absorb food
repiratory
air, gases intake and output
uriniary
water and electrolyte balance trnasport urine, remove waste
reproducive
duh
chemical reactions: synthesis
two or more atoms chemically combined to form a different and more complex substance a+b=ab
decompostion
the breakdown of a complex molecule into its simpler
parts ab=a+b
exchange
rearrangement, atoms exchange postions ab+cd=ac+bd
reversible
look up
ionic bonds are created by what? 5 char.
atoms gainig or loosing electront; weak, assoc. with non-living, atoms are attracted equally and oppositely; micromolecular; occur between metals and non metals
covalent bonds 4 chars.
crated by atoms sharing electrons; stron; ass. wiht living; macromolcular; occir between nonmetals
ph scale:
1-14; 0-7 acicitic, 7 neutral, 7-14 base; hydrogen is measured on ph scale and each increments worth 10
what are the 4 organic compounds and building block?
proteins-amnino acids; carbs-monosaccharides; lipids-fatty acids and glyceral; nucleic acids- neucleotides
hydrolisis
break down of nutrients by using enzymes to break the bone and water t rebuild the original building block
dehydration synthesis
the process by which all organic compounds are joined together. this happends when a water mole. is remove between 2 amino acids
isotonic:
any solution that has the same osmotic pressure as body fluid
hypertonic:
slutions that have a higher osmotic pressure that body fluids
hypotonic:
cells put a solution that has a lower osmotic pressure tha body fluids , swell
diffusion
atoms and molecules and ions ina liquid or air solution to mov efrom areas of higher concentration to areas of lower concentration, concentration gradiend
osmosis
higher to lower, concntration gradient and smipermeable membrand and only water
filtration
toward lesser, hydrostatic pressure
facilitated diffusion
toward lesser, carrier molecule and concentration gradient
active transport-
energy, toward grater , carrier molecule
passive/physical
no energy, diffusion, osmosis, filtration, facilitated diff
acitve/physiological
acitve, pahy pino exo
interphase
dna replicates
prophase
chromatids; centrioles rep. and move to opp. poles; nuclear mem. begins to break down; nucleoli diss
metaphase
chromatids line up on equator; chromatids attach to a spindle fiber with there centromere
anaphase
centomeres break; a complete set of chromosomes move to opp. poles; cytokinesis begins here
telophase
chromatin reforms; nuclear membrane reforms; nucleoli reappear; cleavage furrow forms; cytokenisis in complete
list cell parts
clr men gccm
