percent was 776 ish percent
urea to chloride is 41
carrier chnace was 50
hardy weinberg was 3.92
urea made by nitrogen in amino acids converts to ammonia which is converts to urea
aseptic technique- ethanol disinfectant,closed windows, bunsen burner for updraught ,hold lid above at angle, flame loop and cool then get bacteria, open lid of tube at angle above,flame it then streak loop across, redo lid-heat to culture
loop of henle- descending limb freely permeable to water so diffuses out, fluid inside most conc,first part of upper permeable to ions so flow out,second part actively transported out so medullary conc very high,dct and collecting suct can reabsorb based on ADH conc and vary urine conc.
potato and carrot, cork borer to get tubes,scalpel and tiles and ruler to get 1 cm cube, weigh both and record. Prepare different concs of hypertonics solution from sucrose, place cubes in sucrose for same time, water bath to maintain temp. measure mass after and calc change mass, plot graph and stat test it, whichever veg has higher water potential will have a larger masss chnage as WP gradient is larger.
Add red dyed manometer fluid into tubes, idk i was waffling here, do one with glass beads and see how fluid moves-allows to correct other one for temp and pressure conditions- remove o2 for yeast condition,remove co2 absorber so co2 produced can affect volume and pressure and so fluid movement. add diff fluoride ion concs, same time for yeast, measure distance travelled for each and plot a graph, stat test T for significance
single celled organisms have a high sa:vol, short diff distance so all GE by diffusion

glass used as poor heat conductor so wont trasnsfer heat to seeds,glass is transparent so far red light can be used to inhibit germination and poor transmission of humidity
ball was glomerulus, process was ultrafiltration
zika virus- mosquito nets to not transmit to others and to get into habit to try to eradicate diseases
diff countries have diff temp, humidity and light conditions, so need different control conditions and different seed conditions to limit germination.
in last Q, at shore high salt conc for high WP gradient so water travles in by osmosis, increases upshore as water salt content decreases to maintain same WP gradient
any other questions
