The answer is the first choice: Blue Eyes.
Polygenic traits are those controlled by two or more genes (hence the name "poly" in the term). Other examples would be skin color and height.
Hope this helps! :)
Nucleus to the ribosomes, I think.
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>
<span>Cells control cell division in order to maintain normal cell function. If something happens to the control of the cell division, the healthy cells will divide uncontrollably. These new cells are cancer cells. </span>
The mutations in three genes are responsible for development of cancers:
1. Mutation in proto-oncogenes. Proto-oncogenes normally signal cells to grow and differentiate. Proto-oncogenes can become oncogenes due to mutations which result in the uncontrollable division of the cells.
2. Mutation in tumor suppressor genes. In normal cells, tumor suppressor genes suppress genes essential for cell cycle and that way they prevent uncontrollable cell division. However, after a mutation in these genes, suppression is lost and the cell may progress to cancer.
3. Mutation in stability genes. In normal cells, they have no role either in cell death or growth, but they control mutation rate. Mutation in stability genes results in situation where all genes, including proto-oncogenes and tumor suppression genes, are more frequently mutated.
The
two categories that are used to classify physical changes are Reversible and
Irreversible.
Reversible
means that the matter can convert to gas, liquid and solid and then convert
back to gas, liquid or solid. So it means it can convert back and forth.
<span>Irreversible
means that matter cannot be converted back as it is before.</span>
