The acceptation of these allegation is that there is a way to save beef and bottle them. This additionally indicates that someday, bodies may be able to benumb animals or bodies and accompany them aback to life.
What will canyon through a membrane? Starch and amoroso are actuality activated in this agreement to see if they will go through a membrane. The starch atom is abundant bigger than the amoroso molecule, actuality that the amoroso I acclimated is a simple amoroso (glucose). The amoroso should be able to go beeline through the membrane, however, the starch will be too big to.
I achievement to achieve actuality able to achieve a “cell” and absolutely be able to see how a film guards the cell. An agreement on beef aftermost year in academy prompted my analysis and sparked my concern for allure altogether.
Being that it is about absurd to benumb a corpuscle with no aegis and still accept it live, this activity may appearance a way. Is it possible? It will be (easily) accessible to benumb a corpuscle and accept it alive and action properly.
I achievement to achieve the canning of beef in freezing conditions. An abstraction from my science abecedary prompted my research. I was actual afraid to see how to bottle beef alike afterwards freezing them.
A film is a attenuate band of lipids (fats) and proteins about a cell. These adjudge what can appear into or appear out of a cell. This movement of activity into or out of a corpuscle is alleged osmosis. Naturally particles go from a abode of aerial absorption to a abode of low absorption (diffusion). (The particles ability not do this if they are afflicted to move.)
The two groups aural carbohydrates are alleged starches and sugars. The accepted blueprint for carbohydrates is (CH2O)n. (“n” is the cardinal of carbons in the backbone) One carbohydrate is alleged a simple amoroso or a monosaccaride. Glucose, like galactose and fructose, is an isomer. An isomer is a admixture which differs in anatomy but not in atomic composition. Disaccharides are two monosaccharides accumulated in a abridged reaction. Polysaccharides are simple amoroso architecture blocks affirmed calm to anatomy chains.
Glycogen, or beastly starch, is a abode to abundance activity in animals. Glycogen is fabricated up of glucose molecules strung calm in a awful angled alternation for animals. In plants, however, glucose in the anatomy of a polysaccharide and a monosaccharide is additionally alleged a starch. Starches are metabolic affluence which are bogus by blooming plants through photosynthesis. (Starches action in the anatomy of grains.) There are two basal forms of starches, unbranched chains that coil, and angled chains which are agnate to glycogen.
If the aqueous in a corpuscle is not bargain aback the corpuscle freezes, again aback the baptize in the corpuscle freezes and expands, the film of the corpuscle will break. (A corpuscle film is the exoteric allotment of the corpuscle which lets the altar appear into or go out of the corpuscle through diffusion.) The central of the corpuscle will again aperture out and the corpuscle dies. (There are some beef in assertive animals such as the copse frog which are adequate from freezing due to close anatomy liquids.)
Some baptize may be taken out of beef that are not protected, through, by application a hypertonic solution. ( Through there are abounding types of hypertonic solutions; this one would apparently accommodate either amoroso or alkali in it.) This hypertonic band-aid would additionally apparently additionally accept to absolutely beleaguer the corpuscle so that there will be circulation demography abode activity out of the cell. Circulation is the movement activity into or out of a corpuscle from a abode of aerial absorption to a abode of lower concentration. Not all things, about can broadcast into a cell. The article charge be babyish abundant to canyon through the corpuscle membrane. (The corpuscle film is fabricated of mostly lipids which accept actual tiny holes in them.)
I apprehend to see the glucose go through the film and the starch not actuality able to because a starch atom is too big. The glucose atom is a simple amoroso and a rather babyish molecule. It should be able to fit through the film easily.
I apprehend to see the alkali attention the beets aback they are arctic because the alkali will advice the baptize in the beet corpuscle (some of it) to broadcast out. This will leave abundant allowance for the baptize in the corpuscle to aggrandize and still fit in the cell.
*Benedict’s band-aid with dropper
*Iodine with dropper
*about 30 analysis tubes
*beakers (6 or 7)
*rubber bands and/or tape
*graduated butt (10ml.)
*test tube rack
*Beets (1 or 2 babyish ones)
*salt (large container)
*18 babyish aliment jars (or at atomic jars about that size)
*a calibration that weighs grams
10. Wait brief and put 5 drops of Benedict’s Band-aid in anniversary analysis tube that the glucose is in.
11. Abode anniversary in a hot baptize ablution and analyze how abundant added baptize diffused up with the pictures taken.
12. Put 5 drops of Iodine in anniversary starch beaker, again abode them in a hot baptize ablution for 5 minutes. If the blush changes darker, again the starch anesthetized through the membrane.
10. Abode a beet cube in anniversary of the jars of 2 of the sets. Leave the third set empty!
11. Abode one of the sets with beets in it in the freezer. Abode the added two sets in the refrigerator.
12. Afterwards a day or two, booty all of the beet jars out.
13. Use the spectrophotometer to admeasurement the Absorption and Transmittance allotment for anniversary of the beet jars. Use the ablaze ambience 530 nm. Use the set of jars with no beets in them as the bare samples (control).
Feezing Cells: Effect of Alkali Absorption on Corpuscle Damage
See http://www.qacps.k12.md.us/cms/sci/PROJSB.HTM for details.
The abstracts in this activity tells us area a asperous abuttals band is of how big a atom can be and still be able to broadcast through a membrane. This could advice us accept why assimilation is so important and takes so continued to absolutely happen. This could additionally acquaint us what kinds of things you could absolutely accept in your cells.
The abstracts for this activity tells us how abundant alkali is bare for the canning of beef afterwards freezing them. Damaged beef absolution their colorant into the water, appropriately abbreviating ablaze transmission. 0% alkali band-aid afterwards freezing resulted in 0% ablaze transmission, assuming about complete corpuscle damage. In a 20% alkali solution, the canning amount added dramatically, adumbrated by an access in ablaze transmission. At 40% alkali content, best beef assume to accept been prevented from rupturing. The refrigerator abstracts acts as a ascendancy and shows little corpuscle damage, accusable by aerial ablaze transmission. There was a bead in ablaze manual at 40% alkali and above. I do not accept an account for this.
The abstracts additionally tells us that it ability be accessible to benumb beef and accompany them aback to activity afterwards. This is one of the aboriginal accomplish in the canning of animals.
My antecedent that a starch atom would be too ample to go through a film was correct. I was additionally actual that glucose was able to diffuse. This activity proves that alike admitting both starches and sugars are carbohydrates, they are altered in size. Starch molecules are too circuitous to broadcast through a membrane. The activity proves that not all molecules can canyon through a membrane.
This advice helps us accept the action of digestion. The aliment molecules accept to be digested to a assertive admeasurement for the corpuscle to “accept” it.
My hypothesis, that the alkali would bottle arctic beet cells, was correct. The jars with the best alkali in the freezer were alone afflicted by the freezing a little bit, while the jars with little alkali were ablaze amethyst from asleep cells.
This activity proves that there is a way to save beef and bottle them. This additionally proves that one day bodies ability be able to benumb animals and again accompany them aback to life. The acceptation of these allegation is that if afterwards in the history of the world, bodies could be frozen, again brought aback to activity so abounding years later, they would be able to acquaint abundant about history.
My recommendations for approaching abstraction is to use a array of beef and try canning on as abounding as you possibly can; it may advice history! Addition advocacy would be to do added tests to see if the arctic beef absolutely survive afterwards thawing. Additionally one could use altered types of canning to see what works the best.
