Taste discrimination in young and old Drosophila melanogaster Introduction The ability to discriminate taste is critical for the survival and nutrition of an organism (Sellier et al.‚ 2010‚ Gordesky-Gold et al.‚ 2008). Many animals rely on their taste organs to detect and discriminate various types of taste such as sweet or bitter (Weiss et al.‚ 2011). When these organs come in contact with a food source‚ signals are sent to taste receptor cells. The activation of certain taste receptor cells by

unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The initial streak-plate procedure was performed and placed in the incubator at 37◦C for 24-48 hours. Upon observing the growth on this plate‚ it is fairly obvious that one of the organisms is Serratia marcescens

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

Read in your lab manual about the following agar mediums: Blood Agar (pg 168)‚ EMB Agar (pg 170)‚ Mannitol Salt Agar (MSA)(pg 172) )‚ MacConkey Agar (pg 174)‚ and PEA Agar (pg 176) to answer the following: 1. What does the blood agar select for? Blood agar allows distinction among bacteria based on their ability to lyse red blood cells (hemolytic activity). 2. What color is the blood agar? Blood red color. 3. What are the 3 types of blood agar results and how can you recognize them?
