A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. Such an organism plays a role in its ecosystem that is analogous to the role of a keystone in an arch. While the keystone feels the least pressure of any of the stones in an arch‚ the arch still collapses without it. Similarly‚ an ecosystem may experience a dramatic shift if a keystone species is removed‚ even though that species was a small part of the ecosystem by measures of biomass

I am proposing to write about becoming a network and computer systems administrator‚ one of the reasons I chose this field to do my final project on is I am already in this field of work and feel that I have a fairly good background and plenty of information to share with others. I started in the Information Technology field in 2000 as a System Support Specialist for a fairly good sized Insurance Company.

3.1.3 Computer Network Topologies Network Topology is a network specification that determines the network arrangement‚ connecting the senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and

Security 4th Edition Questions Chapter 6 Questions 1. What is the typical relationship among the untrusted network‚ the firewall‚ and the trusted network? The relationship is that data is only limited to what firewalls allow via specific places called “ports”. There is the untrusted network on the outside‚ then the firewall which prevents unwanted or suspicious connections‚ and the trusted network is what lies within the bounds of the firewall. 2. What is the relationship between a TCP and UDP packet

With the proposed Canadian Keystone XL Pipeline in the midst of approval‚ Americans can look forward to the potential of job growth and less dependencies upon foreign imports. The project proposes a 1‚179 mile‚ 36 inch-diameter crude oil pipe. Crude oil a petroleum product is a liquid composed of hydrocarbons‚ organic compounds and small amounts of metal. It is created through the heating and compression of organic materials‚ over a long time period. The pipeline would start in the town of Hardisty

system that would be able to transport crude oil from Canada into the United States. The pipeline was given the name the Keystone Pipeline System. Originally‚ the pipeline was to run from Alberta‚ Canada to refineries in Illinois. However‚ in 2008 another proposition was raised in order to extend the pipeline even further to down to Texas. The proposition is known as the Keystone XL. The possible construction of the pipeline is a controversial topic. Entrepreneurs believe that such a pipeline will

construction of the Keystone pipeline. The first factor to take into consideration is that the construction of the Keystone pipeline will create an opening of 42‚100 jobs during construction and 50 permanent jobs. It will also contribute to keeping oil refinery jobs. Many environmentalists however tend to oppose this statement by arguing that more jobs will be created when using renewable energy instead‚ such as solar power. Another argument that tends to go against the Keystone pipeline is that it

Keystone species are extremely important in ecosystems across the world. They help control things like population‚ abiotic and biotic life‚ and impacts on human life. Keystone species essentially control the functions of the environment they live in‚ and provide positive and negative effects. In class‚ we studied the effect that wolves had on the environment of Yellowstone National Park. Now‚ I introduce Grizzly Bears and Beavers as my two examples of a Keystone Species. Beavers completely change
