The correct option is BY CONDUCTING EXPERIMENTS THAT EXPOSE THEIR PROPERTIES.
Scientific investigations are always ongoing in all parts of the world, scientists strive to build on existing knowledge by carrying out more experiments that are targeted at obtaining more information above that which is already known.
Afferent nerve fibers carry signals from the somatic receptors to the posterior horn of the spinal cord or to the brainstem. So i beleive it is 4 but not too sure. Hope this helped a bit (:
Answer:
Photosynthesis consist of two types of reaction 1 light dependent reaction 2 light independent reaction or dark reaction.
Explanation:
light dependent reaction
light dependent reaction or light reaction occur in the thylakoid of granum of chloroplast.During light reaction light energy is absorbed by various pigments of the photosystem and is finally converted into chemical energy.
During light reaction water is split in presence of sunlight to form H+ and OH- ions.The OH- ions releases electron.The released electron is then transported through various electron carriers resulting in the formation of ATP molecule by cyclic photo phosphorylation and NADPH by noncyclic photophosphorylation.
Light independent reaction
Light independent reaction or dark reaction occur in the stroma of chloroplast.The ATP and NADPH that is formed during light reaction is used as 3:2 ratio for per molecule of glucose production.
