Humita (from Quechua humint'a) is a Native American dish from pre-Hispanic times, and a traditional food in Argentina, Bolivia, Chile, Ecuador and Peru, although their origin is unclear. In Argentina, Chile, Ecuador and Peru they are known as humitas, in Bolivia as humintas, in Brazil as pamonha, and in Venezuela as hallaquitas. It consists of masa harina and corn, slowly steamed or boiled in a pot of water.
A greater intensity of light causes the pupil to constrict (miosis/myosis; thereby allowing less light in), whereas a lower intensity of light causes the pupil to dilate (mydriasis, expansion; thereby allowing more light in). Thus, the pupillary light reflex regulates the intensity of light entering the eye.
Any change in the level of a limiting factor will affect the rate of. reaction. For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will. be no photosynthesis. As light intensity increases, the rate of photosynthesis will increase as long. as other factors are in adequate supply. As the rate increases, eventually another factor will come. into short supply.
