Which choice describes the forms that energy takes when it starts in the Sun and ends in the sugars of plants? A. chemical potential energy light energy nuclear energy B. nuclear energy light energy chemical potential energy C. nuclear energy chemical potential energy light energy D. light energy nuclear energy chemical potential energy

D. light energy nuclear energy chemical potential energy

Explanation:

Energy transformation that takes place in plants when they change sun solar energy into plant glucose, is :

Light energy (by sunlight) to nuclear energy , chemical potential energy (glucon energy in plant cell - used by plants to make food).

nuclear energy  light energy  chemical potential energy

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
