Bilogical Breakthrough

If Im a BioEntrepreneur in future, I want to make a machine that can Makes Weight Loss Safer. Sometimes, we can not control what we eat or drink, because they are many delicious food around the world, also it's cause our weight heavier and unfitting body type, if the machine equip in body, you can set up what you eat in everyday and exercise, when the limit overthrow, the machine will give a attention the stop it.

I think it's for people who has Heavy weights, because they might not like their body types, and keep doing exercise to burn their fats, but now the drug can help them. On my opinion, after this machine can sell on market, people can easy to having a fitting and healthy body, also it's safety and never afraid to overweight again.In future, all people have good body type.

Biological breakthrough-Dolly the sheep was cloned.

In 1997, the first clone sheep appeared, ewe Dolly, was the first animal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute in Edinburgh, Scotland. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific body part could recreate a whole individual. More specifically, the production of Dolly showed that mature differentiated somatic cells in an adult animal's body could under some circumstances revert back to an undifferentiated pluripotent form and then develop into any part of an animal.

Reflection:
It's really amazing after I read about how did Dolly appeared, I cant believe that Dolly was made by adult somatic cell!!! also she same as Some idea come out of my brain, if Human also can cloned, I believe it will develop of human history, but problems come out, if people cloned success, all around the world only have one kind of people........:) I predict that the world will have more cloned animals because Dolly was a successfull cloned animal, scientist will follow that and they to create another.

Bio Entrepreneurs:Sergey Brin, Larry Page- Google!

Sergey Brin is position of President of Technology at Google, he is the 26th richest person in the world and the 5th richest person in the United States, together with Larry Page. He is also the fourth-youngest billionaire in the world.

Larry Page is an American entrepreneur who created Google with Sergey Brin.

Our Favorite Internet Searching tool: Google!!!

Google is a website that have Internet search, web-based e-mail, online mapping, office productivity, social networking, and video sharing as well as selling advertising-free versions of the same technologies.

On January 1996, Larry Page, who was soon joined by Sergey Brin, two Ph.D. students at Stanford University, California.[6] They hypothesized that a search engine that analyzed the relationships between websites would produce better ranking of results than existing techniques, which ranked results according to the number of times the search term appeared on a page, In August 1996 the initial version of Google was made available.

At now, Google was by far the most popular Web search engine worldwide and most people using that.

Reflection:

It's amazing because Google was created by two Stanford's students! because of google, I can easily to searching website and using E- mail, Im using Goolge everyday, and I enjoy it~ I believe that Goolge would get better in future, If Google has a Friends talking site like MSN or Meebo, people will like it because we can talk to our friend in any time.

Hey Hey Hey!!! My Camera-Eyes

Today, April 17th, guest lecture Dr. Pamela Fong came to Mr. Olson's biology class and explained about different structure of the Eyes. Different areas of the eyes have their own works.

There are some imformation of the eyes structure:

Cornea---- out of the eyes structure, covering the eyes.

Iris---- The colord portion of the eyes, which is opens and closes the monitor amount of lights to get through the eyes.

Lens--- The clear disk to focuses light rays into images, usually Lens are to reflect things.

Retina--- The lining of the eye which contain light-sensitive cells.

Pupil--- is the opening into the center of the eyes.

After this, Dr.Fong showed us different people's the back of the eye balls, it's pretty amazing because they were Dr. Feng's eye balls! I was think about how they put a tiny camera behind of the eyes and captured the pictures, I had a great time to learn about how important of our eyes, If we lose our eyes, all things become chao and dark.

The Dissection:
The second part of the class, Mr. Olson said that we will have a exciting lab, WE HAVE TO CUT OFF THE SHEEP'S EYE! I was feel little scared because that is the first time that I cut off the eye, the skins were so hard because it's protect the inside of the eyes, when we cut off slightly of the eye, many black liquid came out,we saw the lens, sclera and other structure, it's a good experiences to learn about the Eyes, but after the lab, all of my partner are gone and they left the material.........I hope it will not happen in next time. :)

My Own Reflection:
I learned many things about the eyes, also it gives me a attetion to keep my eyes healthy, but i have a question, why we used sheep eyes but not another animal???
However, IT'S A WONDERFUL TIME TO GET EXPERIENCES AND KNOW MORE ABOUT OUR CAMERA.

Phylum Echinodermata -Star Fish

Domain: Eukaryota

Kingdom: Animalia

Subkingdom: Eumetazoa

Superphylum: Deuterostomia

Phylum: Echinodermata

Class: Asteroidea

Order: Clypeasteroida

Family: Asterinidae


Habitat:starfish prefers to live in more sheltered areas such as lagoons, and in deeper water along reef fronts. They generally avoid shallow water on the tops of reefs where the water conditions are likely to be more turbulent. Occasionally they may feed in these areas, particularly when the weather is calm. Consequently care should be taken when reef walking as they can produce a toxic and inflammatory reaction if trodden upon.



Predator: The predators most commonly observed to feed on crown-of-thorns starfish are: the giant triton shell (Charonia tritonis), a puffer fish (Arothron hispidus), two species of trigger fish (Balistoides viridescens, Pseudobalistes flavimarginatus), a shrimp (Hymenocera picta) and a worm (Pherecardia striata).



Prey:They eating clams, and oysters; or any animal too slow to evade the attack (e.g. dying fish). Some species are detritivores, eating decomposed animal and plant material or organic films attached to substrate. The others may consume coral polyps (the best-known example for this is the infamous Acanthaster planci), sponges or even suspended particles and planktons (starfish from the Order Brisingida). The processes of feeding and capture may be aided by special parts; Pisaster brevispinus or Short-spined Pisaster from the west coast of America may use a set of specialized tube feet to extend itself deep into the soft substrata to extract prey (usually clams)[9]. Grasping the shellfish, the Starfish slowly pries open the shell by wearing out the Adductor muscle and then inserts its stomach into an opening to devour the organism.



Anatomy:The body cavity also contains the water vascular system that operates the tube feet, and the circulatory system, also called the hemal system. Hemal channels form rings around the mouth (the oral hemal ring), closer to the top of the starfish and around the digestive system (the gastric hemal ring). A portion of the body cavity called the axial sinus connects the three rings. Each ray also has hemal channels running next to the gonads.Starfish are composed of a central disc from which arms sprout in pentaradial symmetry. Most starfish have 5 arms, but some have more or fewer. Some starfish have shown differing numbers of limbs within a single species. The mouth is located underneath the starfish, on its ventral surface. The spiny upper surface is called the aboral or dorsal surface. On the aboral surface there is a structure called the madreporite, a small white spot located slightly off-center on the central disc which acts as a water filter and supplies the starfish's water vascular system with water to move. Porcellanasteridae employ additional cribriform organs used to generate current in the burrows made by these infaunal starfish.


Reproduction: Starfish are capable of both sexual and asexual reproduction. Individual starfish are male or female. Fertilization takes place externally, both male and female releasing their gametes into the environment. Resulting fertilized embryos form part of the zooplankton.Starfish are developmentally (embryologically) known as deuterostomes. Their embryo initially develops bilateral symmetry, indicating that starfish probably share a common ancestor with the chordates, which includes the fish. Later development takes a very different path however as the developing starfish settles out of the zooplankton and develops the characteristic radial symmetry. Some species reproduce cooperatively, using environmental signals to coordinate the timing of gamete release; in other species, one to one pairing is the norm.some species of starfish also reproduce asexually by fragmentation, often with part of an arm becoming detached and eventually developing into an independent individual starfish. This has led to some notoriety. Starfish can be pests to fishermen who make their living on the capture of clams and other mollusks at sea as starfish prey on these. The fishermen would presumably kill the starfish by chopping them up and disposing of them at sea, ultimately leading to their increased numbers until the issue was better understood. A starfish arm can only regenerate into a whole new organism if some of the central ring of the starfish is part of the chopped off arm.
