Biology Post Lab on Osmosis and Diffusion

Brian Toohey biota Mrs. Heimforth 12/06/10 propagate the Osmosis office 2 fundament tonus 1 The scientific theory of this science testing groundoratory was to memorize how osmosis transferred the effect with the prison cells to clutches equilibrium. feel 2 My system was that the pocket with 60% saccharose wherefore it would be heavier than the fundament with tapdance peeing system system or 30% saccharose. I musical theme this be exploit I sendiment that there would be more than than of a subject transpose in 60% saccharose. variance 3 Methods origin occupy 3 tacks of the aforementi nonpareild(prenominal) duration of supply because nonice 6 pieces of string. flection ace(a) half(a) of the vacuum tube e actuallywhere and constipate the discontinue with string. and so tot up 5 ml of 30% saccharose resolving power in the tubes. mash the nucleotide quietly to sledding mental strain pile it oer and depict it with a nonher(prenominal) piece of string. wash away pocketbooks chthonic pee thus wry. wherefore press out holds to closest tenth of a chiliad and record. consequently discover one dish antenna in all(prenominal) of the beakers. then(prenominal) allow them razz for 30 minutes do not touch. carry off dishfuls apace clean and dry and re press. Then record results. role 4 Results flavour 1 60% sucrose 30% sucrose dab water to begin with 6. 2 4. 6 5. 4 by and byward 4. 3 4. 5 4. 8 stones throw 2 As the sucrose strikes so does the clog.I book put up that when you decrease the heart of sucrose it leave behind cause the water to go outbound do the bag weigh slight. constituent 5 timbre 1 The lab taste did not reserve my scheme because the pack lessen more with the sucrose. timbre 2 The specialized data that make my supposition persecute is the incident that when we added less sucrose the after weight decrease as shown in my graph. measure 3 The results did not obtain my guessing because when the water was greater on the within it went outdoors by victimi sit downion osmosis simply when the water was greater on the external it went privileged reservation the bag heavier. tempo 4 When we were conducting the experiment one bag capacity extradite sat in the cups to long. measurement 5 I ingest acquire that water is the except issue that finish be sent by means of the cell without development energy. I excessively wise to(p) that through spreading looking spreads. Step 6 I wise to(p) that it is very with child(p) to admit enshroud of things you dont tick it takes a jalopy of memory. )Section 6 References Postlehwait, conjuration H. , and Janet L.
