The health of fish depends on the amount of oxygen dissolved in the water. a dissolved oxygen concentration between 6 parts per million and 8 parts per million is best for fish health. a dissolved oxygen concentration greater than 1 part per million is necessary for fish survival. a student’s fish tank contains fish, green plants, and 3800 grams of fish-tank water with 2.7 × 10^-2 gram of dissolved oxygen.

Write a statement using this information that tells why the dissolved oxygen concentration in the water is or is not healthy for fish.

The answer is the first option just took the test

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.
