HEL!! A student was asked to model different relationships between organisms. She used the example of an oak tree and Spanish moss in the picture below to show one of these relationships. The Spanish moss uses the oak tree for support but makes its own food and gets its water from the air. The oak tree receives no benefit but is generally not harmed by the Spanish moss. What type of relationship does this best represent?

mutualism
parasitism
competition
commensalism

Commensalism

Explanation:

Commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm. The Spanish moss benefits and the oak tree neither benefits nor is harmed.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
