The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control
Answer:
...BY CHOOSING A PROPER INDICATOR, SCIENTISTS CAN MINIMIZE THE DIFFERENCE IN THESE TWO NUMBERS,...
Explanation:
A chemical indicator is an agent or substance which gives a visible sign especially a color change when introduced to a solution of base indicating the threshold of the concentration of acid used in the titration procedure. These indicators include methyl orange, methyl red, phenolpthalein. They give a color change when the concentration of an acid as reached a critical limit in order for the reaction to be stopped. These indicators are involved in acid-base titrations, oxidation- reduction reactions and so on. More accurate results of the volume of the required acid or base is obtained by the introduction of these indicators.
Answer:
The correct answer is - C: Energy is neither created nor destroyed, but continually transformed into new forms of energy.
Explanation:
Conservation of energy is the first law of thermodynamics that says that energy is neither generated nor destroyed, can only be transformed from one form to another form continuously. That means no matter what the condition the amount of energy will remain the same, only form will be changed.
For instance, if an electric current will pass through a circuit of a light bulb the electrical energy present in the circuit will transfer into heat and light energy, The amount will remain constant but the one form change to another.
No chemical bonding take place.
And the elements or compounds in the mixtures have no definite proportions.
