Answer:
1) Altering the DNA of organisms is considered controversial because we do not know what circumstances might occur if the DNA which is being altered turns out to have adverse effect on the organism. There are also concerns that altering the genome and producing organisms with better traits might eradicate the particular wild type organisms on the whole.
2)Yes, there should definitely be a guideline as to who can you the recombinant DNA technology and up to what limits. If guidelines are not set up then it can lead to serious devastating results. We might end up making manipulations which can be very harmful for life. Hence, recombinant DNA technology should be used with much care and under strict guidelines.
3) The techniques in recombinant DNA technology has enable us to make precise changes in the DNA at a higher frequency but certain guidelines shall be set up to control the devastating results which might occur. The concern related to life shall be the first and foremost concern while practicing such techniques.
The option that best describes the impact of urbanization on carbon cycle is : ( B ) Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.
<h3>Effects of the organic matter on the environment </h3>
When organic matter decays, this leads to an increase in landfills and as the landfills increases there is also a corresponding increase in the amount in the carbon dioxide which will be released into the atmosphere.Also an increase in the population of an area does not result in the increase of carbon dioxide in the atmosphere.
Hence we can conclude that The option that best describes the impact of urbanization on carbon cycle is Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.

Answer:
A mutation is a change in a DNA sequence. Mutations are commonly caused by mistakes during DNA replication. However, they can also be caused by ultraviolet radiation, exposure to chemicals called mutagens, and infection by viruses. But, a mutation usually occurs when a nucleotide in the DNA gets changed, causing the nucleotide sequence to be copied incorrectly which leads to the wrong code for a protein. This can sometimes be fatal.
