Suppose you measure the mass of a banana before it rots. you measure the mass again days later after the banana has turned black and find that the mass is less. use the law of conservation of mass to conclude what happened to the mass of the banana.

The banana has gotten all mushy and watery, so that makes the mass less.
Maybe?

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
