Write the formula, substitute and solve to the nearest tenth. 1. What is the density if the mass is 200g and the volume is 20cm3?
2. What is the mass when the density is 15g/cm3 and the volume is 5cm3?
3. What is the volume when the density is 5g/cm3 and the mass is 75g?

Conservation efforts have been effective in "increasing the number of endangered species, reducing all the negative impacts of human activity, and preserving wildlife habitats".hope my answer has you : ) 

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f. 

Pretty sure it's d. heterogeneous is separated by physical properties. 

The process is c.convection
