In a hen house, the length of daylight is prolonged by using indoor lighting. the stimulus for egg laying is
(a) food
(b) warmth
(c) light
(d) amount of water.
The correct answer is option (c) light.
Light is found to have a significant effect on egg laying by hens in the hen houses or poultry. Photoperiod is the length of the time within a day to which the hens are exposed to sunlight or artificial source of light. Egg production is reduced if the light intensity and duration is reduced. A peak production of hens is observed with the photoperiod is lengthened or a longer photoperiod.
Natural day light exposure to hens results in the production of not more than 40 eggs. Whereas, a prolonged day light of 12- 14 hours by indoor lighting increases the number of eggs layed to around 60 eggs. Thus, the stimulus for egg laying is the light.
Thus, In a hen house, if the length of daylight is prolonged by using indoor lighting, the stimulus for egg laying is light.

The process of cellular which occurs in the infolded membranes which are shown at B is the folded membranes which comprise of the cristae and gel-like fluid which is between them or the matrix which are the locations of cellular respiration.
Cellular respiration is termed as a set of metabolic reactions and also processes which takes place in the cells of organisms which converts biochemical energy from nutrients into adenosine triphosphate and later it is released as a waste product.
