1. An endoskeleton is the internal support of the structure of an organism like bone, cartilage etc. An exoskeleton is a complex rigid outer covering of an organism which protects the muscles and soft tissues inside like a crab shell.

Answer:
%Volume of ethanol = 15.25%
Explanation:
Volume of water = 250mL
Volume of ethanol = 45mL
The total volume of the solution = volume of ethanol + volume of water
Total volume = 45 + 250 = 295mL
%Volume of ethanol = Vol. of ethanol / Total volume x 100
%Volume of ethanol = 45/295 x 100
%Volume of ethanol = 15.25%
