Sheila conducts an investigation to see how the amount of salt dissolved in water affects the density of the water whichstatement best describes the correct plan for her procedure? the density and the amount of water are controls, and the amount of salt and the type of salt are variablesthe amount of water and the amount of salt are controls, and the type of salt and the density are variablesthe type of salt and the amount of water are controls, and the amount of salt and the density are variablesthe type of salt and the density of water are controls, and the amount of salt and the amount of water are variableso

The type of salt and the amount of water are controls, and the amount of salt and the density are variables.

Explanation:

The amount of a salt dissolved in the water increases the density of the solution, depending on the type of salt we use and the amount and temperature of the water, therefore our controls are the amount of water and the type of salt and the experimentally related variables are the amount of salt and the density of the solution.

the right answer is c. tiempos

el partido de fútbol tiene dos tiempos

in english, this translates:

a football match has two halves

these halves cosists of 45 minutes each.   each half runs continuously. on the other hand, there is usually a 15-minute half-time break between halves.
