Samantha is viewing a real image formed by a lens of a diamond ring. which must be true about the image?
it could not be captured on film. it is larger than the actual ring. it was formed by a concave lens. it is upside down.

The image will be upside down

Explanation:

Since Samantha is viewing a real image through a diamond ring the image would appear to be upside down because we can observe that after reflection of rays, each ray is travelling in a certain direction (and they do obey the laws of reflection). All the reflected rays from the diamond ring are interesting each other at a particular point (converging at a point) and the image that Samantha is viewing is formed at this point (converging point).  

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.
