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.
Full sunlight on a clear summer day has an intensity of about 10,000 foot-candles. A classroom will have an intensity of about 100-foot candles. Photosynthesis and hence rate of plant growth will increase linearly with increases in light intensity from about 100 foot-candles to about 2500 foot candles. A large number of plants are more efficient in use of sunlight and will increase in their rates f photosynthesis up to 10,000 foot-candles.
