Journal Questions 1. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. (Make sure you understand what a hypothesis is before you address this!) Each paramecium growing on its own will be able to grow and flourish because there is nothing stopping it or competing with it. It will be able to grow to its full capacity. When there are both parameciums growing together; one paramecium‚ the stronger of the two

1. Introduction When we say equilibrium‚ it is a state of balance. It is a condition where there is no change in the state of motion of a body. Equilibrium also may be at rest or moving within a constant velocity. A simple mechanical body is said to be in equilibrium if no part of it is accelerating‚ unless it is disturbed by an outside force. Two conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. Thus‚ the following objectives

Global interdependence Visible Imports: Physical goods which are imported into a country. Visible exports: Physical goods which are exported. Invisible imports: services (whatever you cannot touch is invisible eg: interests‚ funds inflows…) which enter a country. Invisible exports: services provided by your country. Balance of trade: income gained from visible exports- costs in paying visible imports. Balance of payments: balance of trade including invisible earnings or costs.+ Trade

percentage of bare ground were recorded and used to perform statistical analysis. No significant variations in the distribution of abundant tree species using chi2 analysis and percentage of fern cover using t-test analysis were observed between the compared sites. No significant variations found in the interquadrat analysis‚ and mean dbh of abundant tree species and percentage of bare ground between the sites compared. The results verified the stated hypothesis and were supported by literature sources
