Diffusion in Agar Cubes
In terms of maximizing diffusion, what was the most effective size cube that you tested? The smallest cube (1cm) was the most effective in diffusion, as the whole cube turned pink. Why was that size most effective at maximizing diffusion? What are the important factors that affect how materials diffuse into cells or tissues? Size was important because of the surface area of the cube determines how much NaOH is needed to diffuse in the cube. The smaller cube had less surface area which allowed…

DNA and Protein Synthesis
DNA Model DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. The 4 types of nitrogen bases are adenine, thymine, guanine and cytosine. The order of the bases determines the DNA’s instructions. The two strands that make up each DNA are antiparallel to each other, which allows the complimentary base pairing. This structure shows the antiparallel strands, which is accurate to the structure of DNA, to improve the accuracy of this model we…
