Ascientist studies the effect of adding different amounts of salt on the boiling point of water. he places his results in the graph below. mc009-1.jpg what are the independent and dependent variables in this experiment? mass is the independent variable, and boiling point is the dependent variable. boiling point is the independent variable, and mass is the dependent variable. there are two independent variables and no dependent variables. there are two dependent variables and no independent variables.

Answer : Option A) Mass is the independent variable, and boiling point is the dependent variable.

Explanation : In the experiment of adding salt to the boiling water, the independent variable is the amount of salt added  because it is not dependent on any other factor of the experiment. Whereas dependent variables is the boiling point of the water  which changes on addition of salt, which means it is dependent on salt addition. Also, the constant variable is the amount of water which does not changes with anything and remains constant throughout the experiment.

answer; protein;

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
