Gill

Each gill arch is lined with filaments which are always submerged in water so they are always kept moist. Gill filaments are able to increase the surface area so that gasses between the water and the blood can diffuse easier. The gill filaments are covered in a large number of tiny folds known as lamella which further increase the surface area available for gas exchange. These filaments have many functions including the transfer of ions and water. Each filament provides a large surface area for exchanging oxygen and carbon dioxide. This makes it easier by allowing more particles to be able to diffuse at any…

use for balance and to steer through the water. Description of gas exchange: As fish live in water their gas exchange system is somewhat different to that of terrestrial animals. They use fragile gills. It is a lot harder to obtain enough oxygen from the water as the concentration is so low, only about 4% and the fish are only able to extract 80% of this. Fish suck water in through their mouth and it flows over the gills. Four bony arches support the gills. The gills are composed of gill…

man and Dark city are very different films. Eastern authors and directors created amphibian Man whereas Dark City was developed here in the United States. These two films were also filmed in very different times. Amphibian Man was filmed in 1962 whereas Dark City was filmed in 1998. Despite these vast differences, these two films have a lot in common. By looking at common themes, examining the progress of society and the effects superhuman powers can have on society, we can understand just how…

Gill netting is a common way to capture species of water life in mass quantities. Marine biologists and aquatic biologists also use gill nets to see what is in the area. Gill nets are large nets that are hung vertically, the trap fish by their gills and other aquatic life gets tangled in the nets. Gill netting causes unwanted species to be caught, ghost nets, and endangered species to be caught. Gill netting effects fisherman as well as the aquatic life when species that are captured are not…

book, as the thirds within the golden section were wonderfully balanced. The type layout design, along with the typeface choice, was in keeping with the style of the Albatross series; simple and clean, and was staggered evenly between the three coloured horizontal divisions. The type used for these designs was a mix of Bodoni Ultra Bold, a ‘faux nineteenth century revival’ (Baines, p. 19), which was used for the publisher’s name, while Gill Sans (still relatively new at the time (1927-8)) was…

I decided to do a research and evaluate Gill Valentine because through some quick background check, I was very interested in that she focused her research on culture of the youth and childhood that are influenced by urban societies and environment. To me, it was her interest in the youth and her ambition toward making contributions to younger generation that made me wanted to know more about the goals of all her researches. Through my research on Gill Valentine, I realized that she is a great…

In On The Outside Rupinder Gill Looking Indian, Rupinder is not happy with her life: “That left my white friends as my only source of comparison, and it seemed fairly clear that we had very different lives.” This is exactly what I feel being as a minority in the country. I would say I am not a part of the Canadian spirit, because I am narrowed of my native root, causing me to become a weirdo who have a totally different identity than the rest. As of the culture, it creates a huge gap between my…

After reading ‘Disability and the Family’ by Carol Gill, I found it interesting to see how society views people with disabilities very differently and that having a disability is the worst thing that could happen to someone. Not only is it difficult for the disabled person but it is also tough on families who are associated with disabled family member. Furthermore, I found it interesting to read about how having a disabled member can change the dynamics of a family and what role each member…

In Gills main points he writes about how people are not learning effectively during their schooling. I agree with what the author is writing about, that the education system has been cultured in ways that may not be particularly realistic. People in school often worry more about the grade than actually retaining the information given to them. I think this is more of a problem now, seeing as assignment and test are put online to complete although the answers are easily accessed through the…
