Answer 4

diabetes and paralysis (spinal nerves cannot repair themselves)

Question 5

Question 11

in plant cells stem cells are found where

Answer 11

• meristems
• TIPS of roots

Question 12

in animal cells stem cells are found where

Answer 12

• bone marrow (ASCs)
• embryotic stem cells (ESCs)

Question 13

what happens in therapeutic cloning

Answer 13

in therapeutic cloning an embryo is produced with the same genes as the patient so the stem cells aren’t rejected
