Katie designed an experiment using a paint roller pan, sand, and water. The steps of the experiment are listed below. Put 3 inches of moist sand on a paint roller pan.
Make a beach by scooping the sand toward the higher portion of the pan.
Put some soil with very small plants growing on it on the sand.
Pour water into the deeper end of the pan.
Pour red mineral oil down the beach and into the water
Move the roller pan to create wave like motion in the water.

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.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
