There numerous of them but some of them would be contaminated soil which can be followed with altered soil chemistry that contains fewer soil organisms that are essential. The third one would be surface runoff due to extensively modified hydrology of the area.
Answer:
12:3:1
Explanation:
<em>The typical F2 ratio in cases of dominant epistasis is 12:3:1.</em>
<u>The epistasis is a form of gene interaction in which an allele in one locus interacts with and modifies the effects of alleles in another locus</u>. There are different types of epistasis depending on the type of alleles that are interacting. These include:
- Dominant/simple epistasis: Here, a dominant allele on one locus suppresses the expression of both alleles on another locus irrespective of whether they are dominant or recessive. Instead of the Mendelian dihybrid F2 ratio of 9:3:3:1, what is obtained is 12:3:1. Examples of this type of gene interaction are found in seed coat color in barley, skin color in mice, etc.
- Other types of epistasis include <em>recessive epistasis (9:3:4), dominant inhibitory epistasis (13:3), duplicate recessive epistasis (9:7), duplicate dominant epistasis (15:1), and polymeric gene interaction (9:6:1).</em>
Answer:
Nanotechnology has bring up major advances in our everyday life. For example, the use of Nanobots that are extensively used now a days in medicine to make surgeries faster and accurate. By the use of nanotechnology, major problems like cancer can be treated by using cell by cell therapy. It is also utilized in curing genetic defects. Major drug designing and drug delivery has been made easier using nanotechnology.
Nanotechnology doesn't have any visible disadvantages but there always remains a fear like introduction of some extra contaminants and toxins in the environment. But mostly i agree with use of nanotechnology for the betterment. Furthermore we don't have any more advance techniques to fight problems than this technology.
Provide structure and support, facilitate growth through mitosis. allow passive and active transport, produce energy, create metabolic reactions, aids in reproductive.
Endoplasmic Reticulum is a long piece of membrane inside of the cytoplasm in a Eukaryotic cell. It connects to the Nuclear Membrane as well. It has numerous ribosomes attached as it helps with protein and lipid synthesis. It has both smooth and rough forms, each which do different things inside the cell.
