Answer:
The competition coefficient in the Lotka-Volterra competition model describes B. The effect of adding one individual of a species on the population growth rate of another species
Explanation:
The competition coefficient in the Lotka-Volterra competition model explains species competing for some common resource. It explains the effect of adding one individual of a species on the population growth rate of another species. <em>They will compete for food</em> with the colonies located near to them. When using equations for predation, the base population model is exponential.
C.The body has higher requirements for water-soluble vitamins
Lets calculate the parameters of the problem. Suppose that the width is x feet. THen, the length is x+30 feet. The area of this parallelogram is given by the product of length and width, hence x(x+30). This has to be equal to 600.
Hence, x is the solution to the equation x(x+30)=600.
x*x+30x=600 hence x*x+30x-600=0. This is a second degree equation and we can calculate Δ=b*b-4ac=3300. The general solution is given by:

.
Substituting, we get that x=-30/4+

or x=-7.5+25*

. This is the width; the length is given by x+30.
