Essay on Ap Biology Your Inner Fish

After reading the book, I began to understand why my body looks the way it looks. I realized that we are all the same inside—from fish to monkeys, and even some reptiles. We all started from the same thing. In my opinion, being human can be summed up into a simple definition—a unique individual. Although we all developed from a similar place, being different makes us human. Each

Please answer these questions then place them in the drop box for this lab. Use Microsoft word if possible.

What is the function of ribosomes? What are their two components? Ribosomes are the cellular components that carry out protein synthesis. Their two components are a large subunit and a small subunit.

3a. Body more than five times as long as broad; front edge of dorsal fin far

When an individual is struggling in life nothing positive comes to mind. Asking for help is something not everyone is comfortable with so they only rely on themselves. Any stranger can approach a person that may seem like they are struggling and help without them expecting it. Some may expect family or friends to help when in need, yet they are the ones that don’t help. A significant theme in Finding Fish is the people who we least expect to help are the ones that actually help the most.

A chemical reaction involving the transfer of electrons rather than molecules is classified as a Redox reaction. A reaction involving the loss of electrons is called Oxidation, and a reaction involving the gain of electrons is called Reduction. Oxidation and Reduction always occur together, as one reactant loses electrons, and the other gains them. This exchange often effects the physical states of molecules, as their solubility is changed with their charge.

B) All humans are nearly identical genetically in coding sequences and have many proteins that are identical in structure and function. Nevertheless, each human has a unique DNA fingerprint. Explain this apparent contradiction.

Neil Shubin, author of “Your Inner Fish: A Journey into the 3.5-Billion Year History of the Human Body” once said, “in a perfectly designed world-one with not history-we would not have to suffer everything from hemorrhoids to cancer” (Shubin 185). In his account as a paleontologist, Shubin constructs a composition about our body’s history using fossils and DNA to compare the physical description of our body to that of the common fish. Upon reading his detailed scientific accounts, I can easily identify with a relation between his episodes and concepts from the general biology laboratory. Even though I was able to identify connections with course ideas and biological concepts throughout the book, I was immediately pulled to: “Handy Genes,” “The Best-Laid (Body) Plans,” and “Making Scents.”

The book Your Inner Fish by Neil Shubin is an interesting novel that shows the evolution of some of our major structures through time. We all know about evolution and the monkeys but we never really looked in on evolution through “our inner fish”. The book was appealing because it helps to understand how we have come to be with some of the parts of our bodies we take for granted, like how we got our developed smell or our advanced color vision. Your Inner Fish is a good way to jump into the evolution of our ancestors and become more knowledgeable about where we came from.

Humans and fish are not closely related on the outside appearance. Most people would not see how we can share the same features with fish, but scientists do know that these two species share homologous features. Homologous is being in similar structures, and having similar genes indicate species are from a common ancestor, but does not have indicated that these features will work exactly the same. Humans and fish are related in the lineage of chordate because human shared homologous features to fish. Homologous features shared by human and fish enlighten the evolutionary pathway from the earliest vertebrate by sharing similar structures of the hands and fins, the development of teeth that diversified into features that showed up from the

often will people think of a nautilus, an organism that is a distant cousin of cuttlefish and squid. These organisms have been dubbed "living fossils" and have been on earth for about 500 million years. The nautilus tends to in front of coral reefs, deep in the ocean. The long existence of the nautilus has allowed its mesmerizing spiral shell to be embedded in some rocks and has become a part of the fossil record.

The author and his colleagues chose to focus on 375 million year old rocks in their search for fossils because amphibians that look dissimilar to fish were discovered in 365 million year old rocks, while fish without amphibian characteristics were discovered in 385 million year old rocks. Thus, it is possible that the evolutionary intermediary, or the “missing link” between fish and amphibians, would be discovered in 375 million year old rocks, between the two time periods. The rocks examined were sedimentary in composition, as the gradual and relatively gentle formation of sedimentary rock under conditions of mild pressure and low heat are conducive to the fossilization of animal remains. Sedimentary rock is also often formed in rivers and seas, where animals are likely to live. This site provides a resource that describes means by which fossils are formed and how the fossil record may be interpreted, and shows some examples of fossils demonstrating evolution through geological periods: http://www.fossilmuseum.net/fossilrecord.htm. In 2004, Shubin and his colleagues were looking for fossils on Ellesmere Island, in northern Canada. This location was chosen because of its lack of human development, as well as of obstructing natural formations and life forms such as trees, which

As many of us often forget, Homo sapiens are just animals like many other organisms. We communicate, build structures, and adapt to our environment like many plants and animals. Biomimicry, as you can tell by its name, is producing objects or materials that mimic other organisms like plants and animals. One tropical organism has an anatomy structure that humans should use to improve scuba diving techniques. The Betta fish, also known as Siamese fighting fish can be found in the South-East Asia. Only a few centimeters in length these fish have bright vivid colors and wide immaculate fins. This is a popular fish commodity for people who like foreign fish or extravagant fish tanks.

This week in class we dissected a frog to learn about its anatomy. We cut the frog open with a scalpel and observed its organs. Some people got females and some people got males. Going into this lab I thought that the frog's anatomy would look very different from a human’s, but I have now concluded that frog and human anatomy are very similar.
