1. Dolly is a sheep that in 1997 was experimented on for cloning.
2. It is called embryo twining.
3. Somatic cells are also called diploids.
4. The gene is inserted into the plasmid.
5. The donor egg cell must have its nucleus removed.
6. Mimi (brown), Medgo (black), Mom (white), petri dishes, microscope, a sharp pipette, a blunt pipette and a chemical that stimulates cell division.
7. 4-Stimulate cell division
6-Deliver baby
2-Remove and discard the nucleus from the egg cell
1-Isolate donor cells from egg donor and germ cell donor
3- Transfer the somatic cell nucleus into the egg cell
5-Implant embryo into a surrogate mother
8. The first things that needs to be waited for is that the nucleus and the cell need a couple of hours to adjust to each other. The second thing is that the cell needs time to divide a few times creating a ball of 16 cells in the petri dish.
9. Brown and Mimi
10. Because they are only able to clone the female version of extinct animals.
11. A couple reasons to clone a human are to have them do things that you don't want to do, or if two people cant reproduce.
12. Sea Urchins
13. He made a tiny noose and tightened it between the two cells.
14. Enucleation
15. Tadpole. Some worked and some didn't.
16. No it can not.
17. Mammals are harder to clone because the egg cells are smaller.
18. Eyestone and Prather
19. It was formed in 1997.
20. The first mammal that was cloned was Dolley the Lamb.
21. They are given a small electric shock.
22. Medical protein Factor IX
23. Stem cells are cells found in all multi cellular organisms.
24. CC was not the same color as rainbow because of the X chromosome. Rainbow has different colored fur due to genes in the x chromosome being turned on or off.
25. Nature vs nurture is pretty much your genetics vs your epigenome. So what is in your DNA, and how you are raised and how environmental factors play into the way you are.
26. NO: The fusion of the goats is not genetically identical to any single goat.
YES: Since the 16 original cells came from the same embryo, they are genetically identical.
YES: All of the offspring are genetically identical.
NO: Each embryo resulted in a genetically unique offspring.
NO: The cows are genetically different, resulting in unique offspring.
27. - Invitro fertilization is the coming together of egg and sperm that produces an offspring that is made partially of the fathers
genes and partially of the mothers.
-Embryo splitting is the splitting of an embryo into multiple embryos with identical genes.
-Somatic Cell Nuclear Transfer is the process of gathering cells whose nuclei are to be transferred into an enucleated egg.
-Multiple Ovulation Embryo Transfer is a process in which multiple and different egg cells are made from an animal and then fertilized.
-Artificial Insemination is the use of a germ cell from a desirable animal in selective breeding.
28. There are many failures do to the the embryo being often rejected by the surrogate mother.
29. A telomere is the DNA sequence found on each end of a chromosome. In clones, they seem to be either longer or shorter than normal, therefore altering the life span of the clones, and causing obvious problems.
30. What is one reason why cloning animals has such a high failure rate?
Well the answer is- There are many failures do to the the embryo being often rejected by the surrogate mother- but the thing is, if it takes so many trials and errors, and the effects are unknown, and it will mess with the very way humans have been created since the beginning of the human population, it it really worth it? At least for humans I believe it is not.

Harvest of Fear
1. GM stands for genetically modified crop and it is a crop that in has been genetically modified in anyway.
2a. GM crops can also help farmers financially because of the GM crops resistance to pesticides.
2b. GM crops can give out many health benefits like that they last longer, and genetically modified crops have less sugar and oil then the original crops.
3a. GM foods are not tested as much because so much is being produced at such a fast rate, so some problems may be found in the food without anyone knowing.
3b. GM crops can harm the environment. Many scientists believe that the GM revolution is uncontrolable and can have a bad result
4. 3 tries.
5a. First is fries. Bioengineers are working to make better cooking oils for healthier fried foods with less saturated fat.
5b. Second is coffee. Companies are looking at engineering coffee beans so that there is less caffeine.
Do you think food should be labeled if it has been genetically modified?
I think genetically modified foods should be labeled. People have the right to know. If they want natural foods they should be able to stay away from genetically modified foods. Also, if people are scared that the GM food will have problems with it they dont have to eat it.
