. Chemistry helps sustain bacteria by protecting the bacteria from outside organisms in the environment out and keeping the bacteria’s contents intact. The Cell Membrane: Is a phospholipid bilayer that completely surrounds a bacterial cell. Cell membrane acts as a highly selective barrier. This barrier prevents materials from diffusing into and out of the cell. This allows the cell to take up chemicals and nutrients needed for survival while keeping the cell components separated from the environment

traded in Africa. The trans-Saharan trade routes were a vast trade network that reached across the continent‚ on which diverse goods and resources were traded‚ and knowledge‚ ideas‚ and religion spread in a phenomenon known as cultural diffusion. Cultural diffusion that occurred along the trans-Saharan trade routes shaped the development of culture in medieval Africa. The trans-Saharan trade routes provided African people access to goods and resources that were not local to their

In today’s society‚ thousands of artificial reefs are manufactured every year throughout the United States using an integration of private‚ federal‚ state and local government funds. Not only are artificial reefs suggested to preserve marine populations‚ but they are also considered to be “economically viable” (‘How artificial reefs are economically viable’). The role of artificial reefs is to attract marine life‚ which brings in approximately $300‚000 a year for many marine wildlife service programs

Artificial Intelligence Artificial Intelligence Growing up‚ I watched and enjoyed movies such as Short Circuit‚ Space Camp‚ and the Terminator. There would be no doubt in my mind that we as humans would be able to create artificial intelligence. I figured it was a no brainer as a watched the robots on the big screen think and make decisions on their own without any human input. Later on‚ as an adult you begin to realize that movies are fiction and it would take a very intelligent human to create

similarities and differences between the diffusion of Buddhism from its origins to 1450 and the diffusion of Christianity from its origins to 1450. Be sure to discuss how each religion gained followers as it diffused. Diffusion of Buddhism and Christianity from their origins to 1450 share many similar traits such as a religious leader who later on helped to diffuse the religion‚ and that the religion was diffused by willing missionaries. Their diffusion differs in what they offered converts and

Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must not exceed the approximate

Allocation of Artificial and Transplantable Organs Everyday many Americans and others across the world are in need of artificial organs‚ which is are man-made devices that are implanted into a person to replace their own natural organ and to perform the same functions as that natural organ would. The ability of this to succeed has been one of the biggest achievements in medicine and still continues to save the lives of people everywhere. However‚ this subject also brings up a lot of controversy
