yes
Because it's denser than the surrounding soft tissues.
they absorb photons from sunlight
No, because there is no such thing as half a photon.
yes proton can absorb gamma ray photons and some xray photons depending on the internal configuration of the proton
They absorb photons.
Electrons can absorb photons and gain energy, and they can emit photons and lose energy.
Glucose is high in the urine of an untreated diabetic. Glucose itself makes the urine hyperosmolar (concentrated with solutes), which in turn makes it absorb extra water from surrounding tissues, which creates extra, dilute urine. This in turn dehydrates the surrounding tissues making the patient thirsty.
Leaves in a plant have light photons whicch absorb the sunlight energy given from the sun . The solar cells are like the light photons and they too absorb sunlight energy
difference in energy between two levels
You and your clothes absorb some of the photons, creating the colors you see.
Yes.
Black clothes absorb more of the suns energy while white absorbs less. Since this energy is in the form of heat to us darker clothes feel hotter. EX) The sun emits photons of light. these photons have a characteristic wavelength to each color: blue green yellow red.....Black clothes absorb wavelengths of light from the sun that dont make up the black color, meaning they dont take in the black wavelength photons, just absorb the colors that dont make black color, like red and yellow. White clothes do not absorb any photons of the visible spectrum so they emit all the photons of light. Since they dont absorb the light energy from the sun they dont get as hot. But will still heat up but from the radiation of the sun.
