Explanation:
Phylum Nematoda is a phylum of invertebrate animals. They are comprised of roundworms (or nematodes). They are identifiable by their smooth and tough outer covering and narrow cylindrical unsegmented body. Their name is etymologically derived from the Greek word nema, nematos, meaning “thread”.
Explanation:
Before the 1920s, films used to be silent with just the action on the scene along with subtitles. Come the decade of 1920 and the advent of new technology, the filmmakers had the possibility to synchronise a soundtrack with the action on the screen. This included dialogues, musical score and special effects. After this development, the movies were called talkies since the audience was able to hear the actors talk with each other. There was no stopping from then on and the next significant development was the introduction of colour. However, colour movies were somewhat slow to catch on, especially when compared to the addition of sound to the movie. Another reason for this slow acceptance of colour was the considerable developing and processing cost it entailed. With passing of time, and improving technology, the colour processing became as affordable as black-and-white films. More and more movies were filmed in colour to a point when the film-makers did away with black-and-white films.
