Question: How does the size of the cell affect its efficiency in exchanging substances through several ways‚ like diffusion? Aim: To plan and carry out an investigation to show the relationship between volume/Cm3‚ surface area‚ and diffusion using agar cubes measured in time/s; and to demonstrate‚ using diffusion‚ why the size of cells is limited‚ keeping the room temperature and pressure constant. Hypothesis: I expect to find that when the surface area to volume of a cell reaches a certain level

Biology Assessment: Influenza Structure: Viruses are non-cellular obligate intracellular parasites‚ requiring a living host cell in order to reproduce. A developed viral particle (virion) lacks the metabolic machinery of cells‚ containing just a single type of nucleic acid (DNA or RNA) encased in a protein coat or capsid. Viruses can be distinguished by their structure and by the nature of their genetic material (single or double stranded DNA or RNA). Viruses that affect humans are more difficult

17th‚ October 2010 Margarita SA: VOL RATIO AND AGAR BLOCKS Conclusion: For this experiment the agar jelly had to be cut in to five different block sizes‚ after that has been done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the

Agar.io is a addictive multiplayer action packed game developed by Matheus Valadares. In the game you are a cell and your goal is to gain as much mass as you can by consuming both pellets and smaller cells without being swallowed by bigger enemy cells. You can either play a deathmatch where everyone is the enemy‚ in a party with your friends or as a colored team that must consume other colors accept for your own. While playing the game‚ there is no set score‚ players have to respawn when all of

The Role of Agarase in Agar-Degrading Bacteria Abstract Agar-Degrading (agarolytic) Bacteria is physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the

4.5 DISCUSSION The bioluminescent bacteria grow well and produce good glowing in the SWC agar media compared to the LA agar media. In LA agar media‚ the production of light was very deem. It also took much time to solidify and the agar media was too soft and forms hole‚ therefore good streaking couldn’t be done. There might be error in the composition of the LA agar media ingredients. However‚ when SWC agar media used‚ there was good growth of bacteria and bright production of light. When comparing

Agar and Media Preparation— Agar plates containing King’s B Agar were often used throughout the experiment to support growth of Pseduomonas fluorescens. A recipe was used that included a mixture of 10g Proteose Peptone #3‚ 1.5g Potassium Phosphate Dibasic (K2HPO4)‚ 30ml 50% Glycerol‚ ~965ml water and 20g agar. The mixture‚ post- autoclave‚ was left to cool and 5ml 1M Magnesium Sulfate (MgSO4) was added and created about 40 plates. King’s B Medium was made using the same procedure as the King’s B

_____________________________________________________________________________ Agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar. Agarose is used widely in gel electrophoresis because it gels at a lower temperature‚ does not contain the inhibitors of virus growth frequently present in agar‚ and has more uniform pore size than that of agar. It is also easily poured and does not denature the samples. In agarose gel electrophoresis‚ DNA or RNA fragments are separated or isolated according

For this experiment you will need 39 agar plates‚ sterile cotton swabs‚ a concentrated amount of Escherichia coli (E. coli)‚ three different levels of antibiotic (Ampicillin: 1mg‚ 5mg‚ and 10mg)‚ a bunsen burner‚ metal tweezers‚ an incubator‚ 27 broths‚ and a ruler which should all be provided through your laboratory. For the first generation‚ you will be using 12 plates. Three of the plates will be labeled G1 control‚ three of the plates will be labeled G1/1 mg‚ three plates will be labeled G1/5
