How fish breathe The water surrounding a fish contains a small percentage of dissolved oxygen. In the surface waters there can be about 5 ml. of oxygen per litre of water. This is much less than the 210 ml. of oxygen per litre of air that we breath‚ so the fish must use a special system for concentrating the oxygen in the water to meet their physiological needs. Here it comes again‚ a counter current exchange system‚ similar to the one we found in the fish’s swim bladder and in the tuna’s muscles

Territorial Behavior in Crickets Results The results gathered from the experiment were promising for the hypothesis. There was a total of 472 Acheta domesticus tested in all trials‚ meaning there were 239 intruder crickets and 239 resident crickets. A chi square analysis was used to determine whether or not the null hypothesis would be accepted. Because there were two groups in the experiment‚ there were two degrees of freedom. If the null hypothesis was true‚ the number of intruder victories and

Big Fish The philosophical twist of mixing fact with fairy tale in story telling put a great spin on the plot. It gave the director the ability to make the impossible seem probable! The movie is about a very interesting father named Ed whom loves to tell facts with a little bit of flavor‚ as quoted in the movie. However we portray them as tall tales‚ but since he tells them with such a seriousness and attachment to his own life you want to believe them. However the son‚ will‚ does not enjoy

Koi Fish‚ Meditation‚ and Ghosts Koi fish has always fascinated me – there is something calming about their simple existence. I am reminded of the meditative state of mind aimed for in Zen‚ where thoughts‚ feelings‚ and sensations are allowed to come and go as they please while the source of our attention is firmly anchored within itself – in the breath‚ in the moment – immersed in the physiological sensory experience yet removed from it. Somehow the elegantly lazy movements of the koi fish bring

Introduction Fish kills are common in natural water systems near mining operations. A major fish-kill took place in the Clark Fork in 1984. These fish kills are due to unnaturally high salinity‚ which is toxic to the indigenous fish species‚ caused by group IA and IIA metal ions in the water. As the mine’s waste seeps into the water supply‚ the salinity‚ and thus toxicity to the fish‚ increases as the various metals dissolve. In this experiment a simulated water sample from Clark Fork‚ or portion

In the movie Big Fish‚ there were many creative elements used to portray the story. Being relatable in a story makes it easier understand. Many of the events that took place‚ may have been slightly fabricated‚ but are events that have happened to us. Meeting your love of your life‚ for example. It is said that “time stands still when you see your future spouse”‚ and honestly it does. Technically the earth does not stop moving‚ it is just a moment where nothing else matters but the one you see. Another
