Answer:
Allows to give rise to different organs.
Explanation:
Since all the cells in our body have developed from a single cell, "the egg or ovum fertilized by a sperm", all of them are identical, that is, they have exactly the same instructions, but depending on the organ they form part, they will use only part of the information or another. This is known as cell specialization.
Thus, the nerve cells possess the information necessary to form hair and the cells that form hair possess the information necessary to form nerves. However, once specialized, nerve cells will form nerve tissue and hair cells will form hair.
In this way, being different recipes, the cells give rise to different organs.
The nucleus is not the only source of DNA, besides it, DNA is also found in the mitochondria of all eukaryotic cells, as well as in the chloroplasts of plant cells and such DNA is called extrachromosomal DNA.
The DNA from the mitochondria (mtDNA) and chloroplasts are small and circular, which are similar to the prokaryotic DNA.
mtDNA contains its own genes that encode proteins that are part of the electron transport chain.

Answer:
With the advancements in the genetic engineering, many concerns are raising day by day on the usage of this technology. Two of the ethical concerns are:
1) The field of genetic engineering allows parents to know the disorders that will arise in the up-coming baby that they will have. As a result, a fetus that is not normal will be aborted by the parents. This action is considered unethical as it comes under killing.
2) The advancements in genetic engineering led to the sequencing of the entire human genome. Scientists suspect that cloning a human will lead to unethical situations like more crime scenes.
The answer is D, digestive.
Because the more humans there are the more the risk for diseases
