Embryonic mass cells are in constant
division, making it much easier to find good examples of each phase of mitosis. The root and the stem are the best place to
look because they contain meristematic tissue that retains the ability to
divide throughout the life of the plant.

Explanation:
Collecting a patient's stem cells and using them for their treatment is known referred to as autologous stem cell transplantation. In autologous stem cell transplantation, stem cells are harvested in the patient's bloodstream or the bone marrow and used to treat or grow organs for the patient.
Using stem cells harvested from your own body is advantageous over stem cells collected from a donor. This is because the case of incompatibility is eliminated. There is also less risk of rejection of organ or graft versus host disorder, where the donor cells attack the host cells thinking they are foreign bodies.
There are fewer side effects and quicker engraftment and therefore quicker recovery.
The changes in environment can cause the raising of the sea level, which can push animals further inward, which in turn destroy habit, as they began to get clumped together vegetation begins to go away, thus resulting in less species, also hotter climate makes sure that animals with very heavy coats of fur, die out pretty quickly if not cooled (over heating)<span />
