Photosynthesis is composed of two main parts (light-dependent and light-independent). photosystem (psi) and photosystem
ii (ps ii) are alike in many ways. how does photosystem i and photosystem il differ from one another?
ps i produces glucose while ps il produces atp.
ps l occurs in the stroma while ps il takes place in the thylakoid
membranes
ps i is a light-independent reaction while ps ll is a light-dependent
reaction
ps i absorbs the longer wavelength of light while ps il absorbs a shorter
wavelength of light

Heyhonestly, probably not. humans have always had a tendency to waste things. whether it's food, cosmetic, infrastructure, or our abandoned constructions,the landscape is littered with the refuseof man. archaeology wouldn't be a developed discipline if humans didn't leave things behind. in a way it makes us human

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
