Answer:
A & C
Explanation:
Primary producers are always at the bottom of the food chain because they are the entry point of energy into the ecosystem. The producers are organisms that produce their own 'food' from abiotic factors and include photoautotrophs and chemoautotrophs. These organisms are then consumed by primary consumers who are subsequently consumed by secondary consumers who are subsequently consumed by tertiary consumers to decomposers. The number of consumers up the food chains can vary with ecososyems and can be an indication of how biodiverse they are. This is how energy and matter are passed up an ecosystem and recycled.
I believe the answers to this would be: Hard parts and deposited quickly. I hope this helped!
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.
