  1. This particular structure in the brain of animals was initially thought to have resemblance with the silkworm. In due course of time the structure was named thus owing to its striking similarity with an animal found in the seas which is known for its ‘contrasting’ manner of reproduction as the males in the group are known to become pregnant.

Which structure in the brain?


  1. The following is believed to be the first picture of something with the origin of the image is uncertain. The top of the image bears the name of a famous chemist who is believed to have made the image. Name the scientist.



  1. First observed by the British astronomer X, this phenomenon consists of the radial flow of gas across the photospheric surface of the penumbra of sunspots from the inner border with the umbra towards the outer edge. X first observed this phenomenon in 1909 while working at the Kodaikanal Solar Observatory in India. Commemorating the event, the India Post issued a stamp in 2008 which is shown below. What phenomenon was discovered by X which is also named after the astronomer X?

  1. Known as an instance of the Marangoni effect in the scientific world, this common phenomenon was first correctly explained by the elder brother of Lord Kelvin, James Thomson. Basically the phenomenon can be explained as follows:

Where the surface of the alcoholic beverage meets the side of the glass, capillary action makes the liquid climb the side of the glass. As it does so, both alcohol and water evaporate from the rising film, but the alcohol evaporates faster, due to its higher vapor pressure. The resulting decrease in the concentration of alcohol causes the surface tension of the liquid to increase, and this causes more liquid to be drawn up from the bulk of the wine, which has a lower surface tension because of its higher alcohol content. The wine moves up the side of the glass and forms droplets that fall back under their own weight.

What is the common term for the phenomenon?
