Dispute: All organisms with vision have similar eyes and similar vision genes. All organisms with vision do not have similar eyes. There are many groups that have similar eyes‚ but not every single organism have similar eyes. Since most of the picture processing happens in the brain‚ the function of the eye is just to capture light to carry to the brain for processing of an image. (149) Human’s camera-like eyes are similar and common to every creature with a skull. However many different types

Thus‚ schooling is how fishes react to a wild aquatic environment. It is a defense mechanism for fishes to ensure their survival in the wild. In a previous experiment‚ we tested and proved that fishes prefer to live in schools and not to live in relative isolation. For this experiment‚ we did a further test on fish behavior‚ targeting on

Some have argued that over the past nearly 150 years‚ Canada has matured and evolved into a "nation" in the sense that it has become "a community of the imagination." That definition sees a nation as a place where the people within its borders display a sense of common identity‚ and agree on certain values.

Eating fish is healthy In this essay I will argue that eating fish is healthy. My main argument will be that fish contains a lot of vitamins‚ minerals and Omega-3 fatty acids. Fish are best known as sources of the fat soluble vitamins A and D‚ though they can also provide significant amounts of some B vitamins. Seafood generally provides little or no vitamin C. The B vitamins are represented to varying extents‚ with the supply of thiamine‚ riboflavin and pyridoxine being the most significant

Model organisms are organisms used for research. They are alive‚ non-human species used for the purpose of studying different human diseases or other related experiments in which human testing would be considered either unsafe or unethical. Scientists study a particular biological phenomenon on a model organism and try to relate their findings to other types of organisms that are more difficult to study. As an example‚ 60% of human disease genes have an equivalent in the fruit fly and nematode worm
