Complexity
None of the above. A rainbow is a visual effect produced by light refraction, not a substance. Solids and liquids can both produce rainbows.
E-mc^2. Energy is related to matter by the speed of light squared.
Also known as photoinhibition, this is caused by the absorption of too much light energy. It primarily affects photosystem II (chlorophyll a), though the exact mode of action is unknown. The damage is generally reversible, but long-term exposure to excessive light may generate damaging oxygen radicals, and result in degradation of the reaction complex. The xanthophylls can protect against photoinhibition by modifiying the action of the photsynthtic complex as a whole, and reducing the energy reaching the reaction centre.
it doesn't matter how bright the light is in order to break free the electrons from the substrate but the kind of colour used is very important.This is because electron will start to move when light is up close to the blue end of the spectrum.
movement of or growth of plant in response to external stimulus. e.g. growth of root towards gravity - geotropism growth of shoot towards the light - phtotropism hydrotropism is exhibited by lengthening of roots towards water source and finally, thigmotropism is growth towards solid objects -support by climbers
No. It is the retina at the back of the eyeball that has the cones and rods that receive stimulus from light and send it to the brain for processing into visual images.
Response. The stimulus is the light.
A stimulus is a DETECTECTABLE change in the environment. e.g. light is a stimulus to an animal or plant if it can detect the light with a sensing eye or chemical
The stimulus in the pupil reflex would be light
umm im pretty sure its responce :) hop i helped A plant growing toward light is an example of positive phototropism.

It is an Edison type screw in base. See related linksbelow for visual types.

An organism responds to a stimulus.
)Movement or activity of an organism in response to a stimulus such as light.
