Answer: By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
The answer is A)<span> the desired gene is inserted into the genomes of the pork.
</span>
The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a <span>higher flesh-to-bone ratio</span><span>.</span>
<span>- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.</span>
<span>- C) is not the right answer because the pork does not have plasmids.</span>
10-On one of his #9 chromosome Rocky has the blood type allele (Bo) since Rocky is hybrid so he have the two alleles B and o in his genotype and B is dominant over o
Through the process of transformation. Hope this helps.
