*How can you use math applied to biology. Mention one thing you can think of. I think that math is applicable to biology using probabilities, statistical models and differential equations in genetic, for example, how __the__ teachers trained us in the school. I think that math applied to biology might play an important role in biological investigation. I know that jelly fish is an invertebrate animal which live **s** in the ocean and __have__ **has** irritating and venomous properties. Taken from: [] To see more: [] []: “[|Biological dispersal], the distribution of spores, fruits and their seeds, etc”, but this is not migration. Dispersion is about short distances. As says the following page []
 * What do you know about jelly fish? What kind of fish is it? If you don't know, find out, cut and paste an image of this fish. Please acknowledge the source.
 * What is dispersion? If you don't know, find out, please acknowledge the source.

1. Click on the following link so that you can read the article. [] 2. Try to locate the words you though you were going to find in the text (question 1 before reading) List the words you found 1. Ocean (num 2) 2. Location (num 3) 3. Creatures (num 4, animal) 4. Research (num 5) 5. ‘Sciences’ appears in the references (num 6, scientific) 6. Developed, developers (num 7, develop) 7. Biology (num 8, zoology) 8. Water (num 9) 9. World (num 10, planet) **Good** 3. Find what the following referents in bold letters refer to in the text: § It refers to Aurelia. **Good** § It refers to the European global shiping and trade. **Good** § **“ this 'foreign' water ”** refers to the water, that was taken for stability (ballast). **Good** § “** its contents ****”** refers to the contents of this water (larvae). **Good** § It refers to the computer model. **Good** § It refers to “human-assisted dispersal” **Good**
 * The species of Jellyfish studied are known as Aurelia and ** these ** are found over much of the world’s temperate oceans.
 * By simulating the movement of the jellyfish over a 7,000-year period the study provides strong evidence that the world-wide dispersal post-dates European global shipping and trade, ** which ** began almost 500 years ago.
 * Ships take in water for stability before a voyage and, despite preventative measures such as mid-ocean exchange/ flushing; ** this 'foreign' water ** and ** its contents ** can find its way into bays and harbours at the ships destination.
 * The computer model could answer similar questions about the migration and introduction of any suspected non-native marine creatures, according to ** its ** developers Professor Matthew England and Alex Sen Gupta.
 * Now we have a tool that can include data on currents, geography and the biology of an organism to help separate natural dispersal ** from that which happens ** through shipping and trade

4. What is happening with the fish? The fish has dispersed for many place of the world, which are impenetrable for this specie. **Good** 5. What explanation scientists had given? The scientists attribute the dispersion to the human influence. They say that the larvae are traveling in the ballast. **Good** 6. What did mathematicians find out? What does the formula explain? The mathematicians found a model which can be summarized as an equation that can determinate the natural capacity of migration of the creature. This equation explains that the jellyfish can not travel to the areas of dispersion of the specie. **Good**
