Have great day
Bodies of molluscs are subdivided into three parts:
*The head that contains the sensory organs and the mouth that contains the radula and odontophores (absent in bivalves).
*The foot is a muscular organ, typical of molluscs, intended for locomotion. It has different shapes depending on the species.
*The visceral mass, as the name suggests, contains the viscera. It is contained in a thin tunic called the coat. It is the mantle that secretes the shell of most molluscs, which serves as protection and / or skeleton and / or regulator of flotation.
Between the mantle and the visceral mass, the pallial rim constitutes a pallial cavity that protects the respiratory organs, and where the metanephridia (excretory organs), the intestine and the genital ducts open.
Answer: The relationship between absorbance and transmittance is illustrated in the following diagram: which is added below.
So, if all the light passes through a solution without any absorption, then absorbance is zero, and percent transmittance is 100%. If all the light is absorbed, then percent transmittance is zero, and absorption is infinite.
