You see an illustration of parallel horizontal lines drawn around the earth. In the geographic coordinate system of the earth which measurements are these lines used for?

The correct option is;

a. Latitude measurement, degrees north and south

Explanation:

The lines of latitude give the measured coordinate of a location towards the north or south in relation to the equator by using a division of surface of the Earth, using 180 imaginary horizontal lines that circles the Earth from the equator to the poles, such that the equator, which is the starting point of the measurement is measured as 0, while at the poles, (north and south) the measurement are 90° each from the equator.

chemical energy is stored in the chemical bonds of atoms and molecules. it can only be seen when it is released in a chemical reaction. when chemical energy is released, the substance from which the energy came is often changed into an entirely different substance.

this chemical reaction releases energy in the form of light and heat. chemical energy is the potential energy stored in the arrangement of atoms within molecules. breaking chemical bonds requires energy, while forming new chemical bonds releases energy.

the atp molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. in this form,energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.
