For example , scientists have been able to insert genes for the surface proteins of pathogenic microbes into the generally harmless vaccinia virus . The result is a sort of ``sheep in wolf 's clothing ' a virus that has the external proteins of a pathogen but dies not cause disease . When an animal host is infected with the engineered virus , the host 's immune system recognizes these proteins as foreign and , in response , develops an immunity that can protect it against the...

Moreover , abortion is not merely an issue of political and legal conflict but of social , cultural and moral conflict as well . Good...

These organisms thrive solely on the amount of nutrients that are dissolved in the water . Phytoplankton converts inorganic nutrients into more complex organic compounds during marked reproductive periods . The concentration of dissolved oxygen has been observed to decrease after the December 2004 tsunami . Dissolved oxygen is strongly correlated to wind turbulence , as well as phytoplankton spikes in reproduction . The decrease in the amount of dissolved oxygen may possibly be due to the requirement of the microorganisms for oxygen which is...

Given these ecological observations regarding the symbiotic relationship between microorganisms and sponges , it is thus of interest to determine the biological reasons behind this ecological relationship . Since the microbe symbionts are generally located within the canals of the sponges , it is thus most likely that their microorganisms thrive in these areas because the microenvironment is rich with nutrients that are beneficial to both the host and the symbiont . In addition , the positioning of the microorganisms within the canals of the...

DNA in our body cells ? The colour of your eyes for instance is influenced by the DNA in your body DNA is responsible in ensuring that body cells grow and function in harmony to form an effective body of a living organism . DNA as already mentioned is hereditary . This means that it is passed from one generation to another through family lines . With the help of technology it is now possible to modify the structure of a DNA and also...

Deforestation can therefore be considered highly ethical and morally upright as it guarantees various communities continued productivity of food (Harris , 1996 . There are numerous resources that are found in our forests which can only be harnessed through deforestation . Resources such as timber , medicine and fuel can only be obtained from the forests through the process of deforestation . These resources play a major role in the growth of a nation 's economy as well as a nation 's economic development . The...

of rainfall because it is cold . Even though some organisms have adapted to living in such harsh environments there are considerably more species in the tropics . The reason for there being so many species in the tropics is a combination of factors . Firstly organisms can live well there due to the extra energy that this part of earth receives . Also secondly it is due to isolation and islandation which promotes evolution into new species by sexual selection . For example , Darwin...
