I love this app so much [...] I recommend Knowunity to everyone!!! I went from a C to an A with it :D
Stefan S, iOS User
The application is very simple and well designed. So far I have found what I was looking for :D
SuSSan, iOS User
Love this App ❤️, I use it basically all the time whenever I'm studying

Stem cells LD Embryonic stem cells can change into ANY type of cell ·undifferentiated, can divide - differentiate into different types of cells, depending on their instructions - found in early human embryos Lo potential to turn into ANY cell! - adult stem cells in bone marrow Lo can only turn into specific cells, eg. blood cells • grown in lab to produce clones, then differentiate into SPECIALISE O CELLS CAN CURE DISEASES! ·bone marrow blood cells, can replace faulty blood cells Embryonic stem cells to make insulin-producing cells for diabetes Lp nerve cells for paralysed spinal injures ect theraputic cloning - embroyo made to have same gentics as paitent - so stem cells would have same genes, so wouldn't be rejected from paitent's body for - embryos used as ANY CELL - help treat diseases ·curing exsisting suffering paitents is more important than right of embryos usually unwanted ones, is not would be destroyed against - human embryos shouldn't be used, as they are a potential human life taking the embryos from a women is painful, and they have a small risk of death.
