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.
The primary and most significant greenhouse gas emitted from human activities is carbon dioxide. Burning of fossil fuels is the major cause of increased carbon dioxide emission.The burning of coal, oil, and natural gas is an important energy source to produce electricity.
Answer:
<h3>The micro-organisms which convert the dead plants and animals to humus are known as decomposers.</h3>
<h3> Examples: Fungi and Bacteria. Decomposers recycle and convert the dead matter into humus which mixes with forest soil and provides necessary nutrients to plants.</h3>
B.
Humans are also part of ecosystems and if they cease to exist, human well being will be affected.
