Answer:
Grasshopper has open circulatory system.
Explanation:
Grasshopper has open circulatory system and they have a fluid cavities called haemolymph. Grasshopper have open circulatory system because the blood is not usually in the blood vessels. The hearts like structure pump the blood into the aorta and the blood flow from aorta in the body fluid, called haemolymph. The heart like structure is located in the upper part of the abdomen and pump fluid to the head and passes through organs and tissues.
Maximum Thrift is a method / philosophy that considers the shortest tree (in number of transformation steps) the best hypothesis about the phylogenetic relationship of a given set of terminals. Transformation step is the cost attributed to the change of character state in a given branch of the tree, be it the change from one nucleotide base to another, amino acids, or the color of an animal's iris. The fewer transformations, the shorter the tree, and therefore the more parsimonious. In this method, what programs do is to investigate as many alternative topologies as possible (or all if their array has less than 25 terminals; see more details below) given their character array. Each will be measured, and the shorter (optimal) trees will be retained as the most parsimonious result.
