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.
The term "photoperiodism" was coined to describe a plant's ability to flower in response to changes in the photoperiod: the relative lengths of day and night. Because flowers produce seeds, flowering is crucially important for the plant to complete its life cycle.
During puberty the testes of the man will begin to produce testosterone. This causes hair growth in multiple areas of the body and the voice change. Similarly, women begin to grow hair but also begin menstruation.
The intracellular is where enzymes need to perform optimally or near optimum.
Explanation:
The Km is the concentration of molecules where an enzyme performs at half of its maximum velocity (Vmax). Therefore, when molecules are near Km the enzyme is able to hydrolyze molecules nearer its Vmax.
