Diffusion In Agar Cubes Lab
- The cube most affected in terms of maximizing diffusion would be the smallest one, this was visually evident as even when we cut through the smaller one there were no signs of a white square to show that the diffusion didn’t fully sink it which subsequently led me to believe it fully had absorbed the hydroxide the most.
- This absorbed better because it had less of a size in comparison to the other two agar cubes meaning less surface area for the hydroxide to settle into, this was best represented by a surface area to volume. Some important factors would be how materials diffuse into cells or tissues. There should be a high surface area and a low volume.
- A large surface area would be inconvenient for growing cells as it would make almost too much volume to diffuse into. Meaning over time as the cell gets larger the important factor that we just discussed above (volume ratio) would get decreased, which will eventually interfere with the diffusion, which is why it will result into an inefficiency.
- The SA:V of Cube C will most effective at maximizing diffusion as it’s within a smaller volume, while having a large surface area.
- It is able through multicellular and dividing of cells and if they increase in size it makes it more difficult with the exchanging of gases which leads to the causing of disfunction.
- It all comes back to SA:V, if bacteria reached the size of small fish the surface area will become smaller then its actual volume, where it would in result not be able to function as diffusion would be in-able of happening and the materials would not reach its center.
- Being multicellular helps reach a higher surface area which then helps us diffuse in nutrients in larger quantities which means we do it much more efficiently.

Protein Synthesis Model
Translation/Protein Synthesis Model- Concluding Questions
Translation happens in 3 stages: Initiation, elongation, and termination.
Initiation is when the mRNA attaches itself to a small ribosome subunit, then the 2 ribosome subunits bind to each other.
Elongation happens when the ribosome holds mRNA which allows the complimentary tRNA to attach to the binding sites, which then will have tRNA to bind each site, that affects change, the change occurs through when the tRNA being released binds to the neighbouring amino acid) leaving the tRNA empty will leave the ribosome, moving along the mRNA, and will go to the “P” SITE, which then allows the NEW tRNA to bind with the mRNA codon at the “A” site.
Termination is the elongation continuing until the mRNA reaches the codon that reads stop which is the 3 letter codon that doesn’t have matching tRNA so no new amino acid is added.
2) the elongation process of this lab was a good representation on how accurate the movement of the ribosome was along the chain, the inaccuracy of this lab was difficulty of moving it smoothly along the surface of the paper and in attempt to show each amino acid attaching onto eachother

DNA model
- Explain the structure of DNA – use the terms nucleotides, antiparallel strands, and complimentary base pairing.
DNA (deoxyribonucleic acid) is a nucleic acid polymer. The structure is unique with its double helix ladder form with rings. The backbone is made up of a sugar, deoxyribose, and a phosphate. Its rings consist of two bases which are hydrogen-bonded to each other, these are adenine to thymine, and guanine to cytosine or simply A, T, C, and G. there are complimentary pairs with A bonding with T and C bonding with G. The strands of DNA are always opposite on the other side from each other or, anti-parallel strands. They compliment each other that way creating one backbone which is opposite to its partnered backbone.
2. How does this activity help model the structure of DNA? What changes could we make to improve the accuracy of this model? Be detailed and constructive
I believe that the color coordination of this activity helped me organize visually what the bonding pairs were, along with the beads being paired with the pipe cleaners as the beads were in coordination of each other, which allowed us to visually present the sugar phosphate of the antiparallel strands.

Great work Allysha, I really liked the detail in which you described the DNA model!

October Reflection
I chose the cupcakes we did in October called Whacky Cakes! I absolutely loved this recipe as Im huge fan of chocolate so in an obvious result I enjoyed them very much. The best part about making this recipe was decorating the cupcakes although the icing wasn’t as thickly spread out on the cupcakes as I hoped it still turned out okay. My group did a very good job at staying on task throughout this lab , nobody was off task as we in result got out of our unit on time for lunch! One thing I probably would’ve done different is the taste of the icing as I found it a bit dull, in my opinion in subsitute of the regular icing, cream cheese icing that usually goes on red velvet but would’ve easily work for this recipe just as well would’ve been just tad bit nicer of a touch! but thats not to say that I didn’t enjoy it. I have no complaints regarding my group as I feel everyone contributed to a role in helping and cleaning throughout this lab.
Ballad Poster (The Mermaid)
To yon fause stream that, near the sea,
Hides mony an elf and plum,
And rives wi’ fearful din the stanes,
A witless knicht did come.
The day shines clear–far in he’s gane
Whar shells are silver bright,
Fishes war loupin’ a’ aroun’,
And sparklin’ to the light.
Whan, as he laved, sounds cam sae sweet
Frae ilka rock an’ tree;
The brief was out, ’twas him it doomed
The mermaid’s face to see.
p. 152
Frae ‘neath a rock, sune, sune she rose,
And stately on she swam,
Stopped i’ the midst, and becked and sang
To him to stretch his han’.
Gowden glist the yellow links
That round her neck she’d twine;
Her een war o’ the skyie blue,
Her lips did mock the wine;
The smile upon her bonnie cheek
Was sweeter than the bee;
Her voice excelled the birdie’s sang
Upon the birchen tree.
Sae couthie, couthie did she look,
And meikle had she fleeched;
Out shot his hand–alas! alas!
Fast in the swirl he screeched.
The mermaid leuch, her brief was gane,
And kelpie’s blast was blawin’,
Fu’ low she duked, ne’er raise again,
For deep, deep was the fawin’.
p. 153
Aboon the stream his wraith was seen,
Warlochs tirled lang at gloamin’;
That e’en was coarse, the blast blew hoarse,
Ere lang the waves war foamin’.
Literal Meaning:
A fisherman finds a mermaid and captures her.
3 examples of Imagery:
Fishes war loupin’ a’ aroun’,
And sparklin’ to the light. (lines 7-8)
Represents the vivid imagery he experiences before coming in contact with the mermaid.
Gowden glist the yellow links
That round her neck she’d twine; (lines 17-18)
The rope that goes around her in attempt to capture her.
The day shines clear–far in he’s gane
Whar shells are silver bright (lines 5-6)
Leads up to the vivid sight he soon see’s which is the mermaid.
2 examples of lyric qualities:
-Out shot his hand–alas! alas! (Line 27)
Repetition of the word “alas”.
-The mermaid leuch, her brief was gane,(A)
And kelpie’s blast was blawin‘,(B)
Fu’ low she duked, ne’er raise again,(A)
For deep, deep was the fawin’. (B) ( lines 29-31)
Rhyme scheme of pattern of A,B,A,B
3 examples of figurative language
-The smile upon her bonnie cheek
Was sweeter than the bee (Lines 21-22)
Personification of how her smile represents the sweetness of a bee.
-Her lips did mock the wine (line 20)
Personification on how her lips are representing the shape of a wine bottle- also can be a metaphor comparing her lips to a wine without using “Like or as”.
Whar shells are silver bright (line 6)
Hyperbole on how bright the sea shells look.
Theme of the ballad :
Deception, as the mermaid trusted the fisherman, where he tricks her into having some sort of human connection with him only so he can selfishly trap her with “golden links”, also known as a rope to capture her.
Good job 🙂
