Answer:
Explanation:
a)Organ transplantation requires that the donor organism and recipient be genetically close so that the graft or transplant will not be attacked by the immune system of the recipient leading to rejection and damage. Squeaky is likely to be made up of a different genetic configuration compared to laboratory inbred FG426 mouse
b) ips (induced pluripotent stem cell) on the other hand can benefit squeaky since the cells are somatic cells such as B cells, Keratinocytes, neuronal progenitors cells, kidney and muscles gotten from the donor that are reprogrammed by reactivating silent genes through fusing of another different cell such as ES (embryonic stem cell) and introduction of some transcriptional factors such oct4, sox2,kf4, and k-myc leading to transcriptional activity and DNA methylation. This induced pluripotent stem cells can be grown into organ that can be transplanted to the recipient who was initially the donor of the reprogrammed somatic cells. Because it is from the host, the transplanted organ is not likely to trigger immune response compare to those grown from ES from other bred.

There are three types of meristems on the basis of position, i.e
- Apical meristem.
- Lateral meristem.
- Intercalary meristem.
<h2>
Explanation:</h2>
A meristem is the tissue present in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Generally differentiated cells(the cells other than meristems) do not divide and produce of a different type of cells.
Meristems are classified on the basis of their location in the plant:
- Apical meristem - these are the meristems located at root and shoot tips of the plant.
- Lateral meristem - these are the meristems located in the vascular and cork cambia in plants.
- Intercalary meristems - these are the meristems located at internodes, or stem regions between the places at which leaves attach, and leaf bases.
Result: There are 3 types of meristems.
