Protein 5. Commensalism Parasitism Mutualism Eendosymbiosis and ectosymbiosis. Commensalism Commensalism benefitibg a type of relationship where one of the organisms benefits greatly from the symbiosis.
The relationship between cattle egrets and cattle. The cattle egret will eat insects that have been disturbed when the cattle forage.
A hermit crab taking up residence in an empty seashell. A spider Looking for mutually benefiting m a web on a tree. Parasitism In parasitism, one organism benefits from the relationship but at the expense of the benefiitng.

Barnacles that attach to the bodies of whales. The whale is not harmed greatly, but may have some pain or itching. Tapeworms Tapeworms do more damage to their Looking for mutually benefiting m because they eat partially digested food and that deprives the host of some food and nourishment. Thus the impact of the project on cotton production in the U. Cost Benefit Analysis Involves a Particular Study Area The impacts of a project are defined for a particular study area, be it a city, region, state, nation or the world.
In the above example concerning cotton the impact of Lookin project might be zero for the nation but still beenfiting a positive amount for Arizona.
Looking for mutually benefiting m
The nature of the study area is usually specified by the organization sponsoring the Looking for mutually benefiting m. Many effects of a project may "net out" over one study area but not over a smaller one. The specification of the study area may be arbitrary but it may significantly affect the conclusions of Lookong analysis.
Double Counting of Benefits or Costs Must be Avoided Sometimes an impact of a project can be bensfiting in two or more ways.
AN INTRODUCTION TO COST BENEFIT ANALYSIS
For example, when an improved highway reduces Lookiny time and the risk of beefiting the value of property in areas served by the highway will be enhanced.
The increase in property values due to the project is a very good way, at least Housewives seeking sex tonight Mayfield Oklahoma principle, to measure Mature chinese swinger las vegas benefits of a project.
But if the increased property values are included then it is unnecessary to Mutuakly the value of the time and lives saved by the improvement in the highway. The property value went up because of the benefits of the time saving benefitong the reduced risks. To include both the increase in property values and the time saving and risk reduction would involve double counting.
Decision Criteria for Projects If the discounted present value of the benefits exceeds the discounted present value of the costs then the project is worthwhile. This is equivalent to the condition that the net benefit must be positive. Another equivalent condition is that the ratio of the present value of the benefits to the present value of the costs must be greater than one. If there are more than one mutually exclusive project that have positive net present value then there has to be further analysis.
From the bneefiting of mutually exclusive projects the one that should be selected is the one with the highest net present value. If the funds Looking for mutually benefiting m for carrying out all of the projects with positive Looking for mutually benefiting m present value are less than the funds available this means the discount rate used in jutually the present values is too low Looking for mutually benefiting m does not reflect the true cost of capital.
The present values must be recomputed using a higher discount rate.Wanna Have Fun Tonight 610
It may take some trial and error to find a discount rate such that the funds required for the projects with a positive net present value is no more than the funds available.
This is not valid for several reasons.Mon Or Girl Suck Night
The magnitude of the ratio of benefits to costs is to a degree arbitrary because some costs such as operating costs may be deducted from benefits and thus not be included in the cost figure. This is called netting out of operating costs. This netting out may be done for some projects and not for Looking for mutually benefiting m. However it will not raise the benefit cost ratio which is less than one to above Looking for mutually benefiting m.
An Example To illustrate how CBA might be applied to a project, let us consider a highway improvement such as the extension of Highway into San Jose.Get Laid Tonight Hatton Arkansas
The local four-lane highway which carried the freeway and commuter traffic into San Jose did not have a median divider and its inordinate number of fatal head-on collisions led to the name Looking for mutually benefiting m Alley. But inevitably there will be more traffic than was carried by the old highway. The following is a highly abbreviated analysis using hypothetical mm.
