The effects of gene mutation on Olfactory Sensory Neurons in Caenorhabditis Elegans Amira Brown University of California, Santa Barbara Abstract This experiment examines the effects of distinct odorants on chemotaxis behavior of the nematode worm, Caenorhabditis elegans (C. Elegans). Nematode worms are appropriate for sensory physiology studies because its neuronal wiring is similar to that of humans. We focused on the role of three sensory neurons in the nose of the nematode—the 1) AWA and 2) AWC neurons are involved in chemo-attraction and the 3) AWB neurons are involved in repulsion. With the use of RNA interference (RNAi), we diminished or eliminateed specialized proteins within the worms to test if their olfactory neurons allowed them to move toward or away from a specific smell. If a certain gene was turned-off and the nematodes did not behave as anticipated, this would mean that that gene plays a significant role in their olfactory organ. The genes that were used were CEH-43, LPR-4, ODR-10, and L4440, which allowed us to determine how much of an impact it had on the C. elegans’ chemotaxis index. Introduction Being members of the Nematoda family, C. elegans are best classified as nematodes that take the form of long cylindrical bodies with tapering ends that survive by feeding on bacterium and are free-living in soil (Edgley, 2015). C. elegans possesses a genome that presents a simplified prototypical nervous system that is particularly easy…

Exclusively, students will build up a bunch of small-scale assemblages of tectonic drawn at 1:50 scale, and in isometric, with 30 degree angles x and y axes. The components that include a regular infrastructural layer in the urban space: vehicles, bus-stops, steps, portions, swimming pools, road signs, traffic lights, footbridges, ticket machines, urinals, street arts, trees, booths, bicycles, etc. Finally, every student will create a narrative map outlining the future histories of Sydney's 3rd…

an ibis’s eye view of the landscape that links Bundaberg to the beach from where Bert took his first brief but exhilarating flight into a life of adventure. An even greater flood of adrenalin must have rushed through his veins when, in 1920, he set off on an epic flight from England to Australia. With icy winds wiping across his face, he flew his tiny and fragile bi-plane high about the land and the ocean until, nine hours after takeoff, he was forced to abort his journey in Italy. Although…

Manly is beachside suburb that has undergone change in the past 20 years. It is a 15km2 beachside suburb full of sand, shops and resorts on the Sydney’s northern beaches. It has a national park within its boundaries and stretches right along to the North Head of Sydney Harbour. It is located at 33.7922⁰S, 151.2826⁰ and 17km from the Sydney CBD. The traditional indigenous owners of Manly are the Guringai People. The character of the community 20 years ago has changed greatly to become the present…

AUSTRALIA Most international visitors to Australia land in its oldest and largest city, Sydney, whose population of 4.5 million sprawls from the city center of Sydney Harbor (home of the iconic Opera House and Harbor Bridge) and Central Business District to the outlying suburbs of Parramatta, Bondi Junction and the Northern Beaches. Sydney is Australia's cosmopolitan hub of architecture, fashion and business-but has a laid-back beach culture, which is distinctly Down Under. On the weekends,…

Dory tells Marlin that she has short term memory loss. Soon after they encountered three fish friendly sharks and they invited them to their anti-fish-eating counsel. When Marlin went to talk, he got distracted by a diver’s goggles, which had an address of where Nemo is being kept, which is P. Sherman 42 Wallaby Way, Sydney. Marlin and Dory fight over the goggles because Dory can read it and she tried to ask where Sydney is, but then Dory gets hurt and blood is released from her and sniffed by…

The diverse architecture and landscape found in and around the antiquated community of Beechworth, a small town located in the northeastern part of Victoria, Australia is quite superb when compared to other places that offer so many natural wonders. One of the cities best features is that it is located in the colorful southeastern region of the country. In this part of the world, you will find an enormous mix of plush green rainforests, red sandy deserts, craggy ocean cliffs, emerald green…

Bays Precinct offers a great opportunity to extend Sydney’s ferry Service and when redeveloped will offer to introduce new timetabled inner harbour ferry services. The introduction of a new ferry stop at White bay Power Station with the increase in productivity at White Bay and the potential increase in the number of commuters activity makes a stop here viable. With people disembarking from cruiseliners at White Bay Cruise Terminal to other locations, a stop here is a necessary in terms of…

Flinders Street Station, constructed from 1905 and opened in 1910, stands to be one of Melbourne’s major social and cultural landmarks and Australia’s busiest railway stations as it is one of the most heavily used public spaces in Melbourne. The very first railway line was constructed in 1854, after which saw further lines and platforms added that were also repositioned prior and after manufacture of the main building. An enthusiasm for railway development quickly sparked with the discovery of…

About Melbourne Melbourne is one of the most beautiful cities in the world with a population of 4.8 million which is 19% of Australia’s population. Melbourne is the second largest city in Australia and is also the capital city of Victoria. Melbourne is also the most livable city in the world.
