Relate & Review- "My Inner Fish"

 In the episode of "Your Inner Fish," Dr. Neal Shubin talks about how many of the features we inherit are from fish, especially our embyronic structure. Some questions that interested me is what the Sonic hedgehog gene responsible for, which is to tell cells in a particular order due to the signals and generating multiple digits. The Sonic hedgehog gene helps form the multiple digits along the hand.  It is located in the embroyo and comes in when interaction of proteins lay down a basic pattern. It can be increased where it can form more than 5 finger digits like Kamani, and can decrease. Another interesting question is what did Tikataalik use its' neck for in the water, which is to watch out for other predators, and hunt smaller prey. Tiktaalik are the first transitional fish to live underwater and go onto land. They are tetrapod primitive fish that descends from pioneer amphibians. These concepts relate  to knowing the structure and defining characteristics of fish and how there structures are very similar to humans, mainly in the Chordates Part 1 and 2 Vodcast.

4th Blog Post

On my 20 time project "Hybrid Vehicles," I decided to change of building the hybrid model, to creating an infographic to prove that Hybrid Vehicles are beneficial. This was not only because of Mr. Orre convinced me to do the infographic instead of building the hybrid model, but actually realzing that the hybrid model, which I'm building out of cardboard,will not prove anything that hybrids are beneficial, and takes a lot of time. After I finish my infographic, I am going to keep practicing on what I am going to say for my 20-time Ted talk.

Fire Corals

Fire Corals, are classified as a Hydrozan in the Cnidarian phylum. They use their long hairs that protrude from their skeleton to trap their prey and gets their food from Zooxanthealle. Then they produce clusters of stingning cells that inflict the stings on human skin. Their polyps reproduce asexually, and are near microscopic size and mostly are imbedded in the skeleton and are connected by minute canals.  These corals contain gastropores and dactylopores, that are visible on their smooth surface. Fire corals can reproduce asexually through fragmentation. However their brittle skins are easily to be broken during storms or by divers. This relates to learning about Hydrozans in the Part 1 Invertebrates Vodcast which is part of the Phylum Cnidaria that is hte odest group containing specialized Tissues.http://www.arkive.org/fire-corals/millepora-spp/.
