Please help me write the following in your own words Please!! 1. SQUASH AND STRETCH
This action gives the illusion of weight and volume to a character as it moves. Also
squash and stretch is useful in animating dialogue and doing facial expressions.
How extreme the use of squash and stretch is, depends on what is required in
animating the scene. Usually it's broader in a short style of picture and subtler in a
feature. It is used in all forms of character animation from a bouncing ball to the
body weight of a person walking. This is the most important element you will be

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
