Answer
1. Chemicals - Tongue2. Light - Eye
Explanation
This question involves connecting each stimulus-- chemicals and light-- with the correct sense organ. The stimulus represents any element that creates a sensation which an organism can process or react to.1. Chemicals: Whenever an organism interacts with certain chemicals, such two main reactions occur. When chemicals come into contact with the eyes, they may cause irritations or allergic reactions. When chemicals enter via mouth, however, they reach the tongue, or more precisely the taste buds. The tangibility to differentiate between different flavors depends on a series of complex reactions of these molecular compounds with the 2000-8000 taste buds present in our tongue; these taste buds actually recognize the chemicals present in the food in our mouths. Therefore, with relation to this stimuli, the most appropriate organ would be the tongue.2. Light: Light is detected and processed by the eye. The cornea first collects incoming light and focuses it to subsequently transmit it through the pupil. The iris (the colored partordinatelyt that sheaths the eye) advises the pupil-- the gateway permitting light to enter the retina that lines the eyeground; the retina consists contains extremely sensitive rod cells, and cone cells that adjust to diverse light conditions. Ergo, concerning this stimulus, 'Eye' is the suitable organ.
