Transgenic bacteria could be very efficient at removing oil spills from seawater.Scientists believe that they could consume large quantities of oil from the BP spill and help the Gulf recover. These oilspills are a type of pollution and cause an impact on the environment.

 This trangenic oil-eating bacteria, can cause the emergence of various other mutant bacteria and end up being harmfull to humans (causing  respiratory, skin or gastrointestinal complications) and the environment (the broken down products of the oil are released twice as fast causing CO2 increase). 

To minimize these potencial negative impacts scientists could introduce a genetic material into a bacteriophage (a virus that infects bacteria) to give  microbes that already exist in the ocean the power to break down oil.

Another possible way to avoid the negative impacts of these bacteria is to create a new organism that thrives in the ocean, eats the oil, and needs a certain stimulant to live, that way when they finish their job the organism could be easily killed.

A male giraffe has 31 chromosomes in each of its sex cells. How many would be present in its body cells?
svp [43]

Answer:

62 chromosomes.

Explanation:

Sex cells are formed undergoing meiosis, which means that they contain a haploid number of chromosomes. (Half the number that somatic/body cells contain). 31 is half of 62, which means that the diploid number of chromosomes in the body cells of a giraffe would be 62.
