Stem cell webquest

Stem cells are the basis of all our cells, during the stages of development in the mothers womb, a baby will produce these cells, out of its spinal cord, to be made into completely new cells. A stem cell could turn into a nerve cell, tissue cell, muscle, heart, brain, anything and everything. Unfortunately the best way to get them at this moment is from a fetus, or a still developing baby or fetus taken from the womb. (Abortion is the most common way of getting them)
Stem cells have been known however, to appear in adults as well, bone marrow, peripheral blood, brain, spinal cord, dental pulp, blood vessels, skeletal muscle, epithelia of the skin and digestive system, cornea, retina, liver, and pancreas, And the list is still growing!

Harvest of fear activity

A "GM" crop is a genetically modified version of an otherwise common crop, for example, say that you have a potato plant, and want it to more resistant to some critters and pesticides, the final version of that new potato plant would be a genetically modified crop. (GM for short)

The art of genetically modifying crop has the potential to do great things for the society, but also great harm, super fast growing crops, as well as the ability to be more resistant to critters and chemicals can be a great advantage, but these "super crops" may become, "super weeds" by passing the immunization gene on to cross pollinated plants,

It took me and Brad ( Brad was using an Ipad so we did the simulation together) around 8 times I think, I cant go back and check however because the computer I'm using doesn't have the adobe shock-wave player required.

Fruits are being modified to last longer on market shelves, and to have more vitamins and minerals, and pizza is being modified by the animals used to make the cheese, pepperoni, and of course, the wheat is being modified to be more resistant to pests and other things.
