Answer:
Enclosed rhyme (or enclosing rhyme) is the rhyme scheme ABBA (that is, where the first and fourth lines, and the second and third lines rhyme). Enclosed-rhyme quatrains are used in introverted quatrains, as in the first two stanzas of Petrarchan sonnets.Enclosed rhyme (or enclosing rhyme) is the rhyme scheme ABBA (that is, where the first and fourth lines, and the second and third lines rhyme).

The Two types of nerve cells is rodes and cones.
The retina is the film of the eye like the film of a camera. The retina is the light-sensing part of the eye. It converts the incident light into electrical signals and sends them to the brain.
The retina is the film of the eye like the film of a camera. The retina is the light-sensing part of the eye. It converts the incident light into electrical signals and sends them to the brain.The retina is a layered structure with several layers of neurons interconnected by synapses. The only neurons that are directly sensitive to light are the photoreceptor cells. These are mainly of two types: the rods and cones. Rods function mainly in dim light and provide black-and-white vision, while cones support daytime vision and the perception of colour. A third, much rarer type of photoreceptor, the intrinsically photosensitive ganglion cell, is important for reflexive responses to bright daylight.
