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.
B just specialized beaks pls put the answer like Brainly answer
The answer is F, false. Natural selection is still involved, with stronger and more procreative individuals spreading their genes. An example of when natural selection is not involved would be when human breeders look for specific traits and breed accordingly.
The appropriate answer is C. ANCESTRAL FINCH. The study of these birds on the Galapagos island led to Darwin proposing his theory of natural selection. Darwin collect and preserved samples of the finches he observed while on his travels.
He did not observe anything unique about the birds until after he returned home. He focused on the differences in the beaks of the birds. It is then that he started to work on his revolutionary theory.
Answer:
D
Explanation:
Alternative energy is best defined as the use of energy sources other than traditional fossil fuels, which are considered environmentally harmful and are in short supply. Fossil fuels consist of natural gas, coal, and oil. Currently, fossil fuels are the most used energy source to heat our homes and power our cars.
