Cell wall might be the answer
The state of matter with a specific volume but no definite shape is the <u>Liquid</u> state.
<u>Explanation:</u>
There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.
Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.
Answer: tapeworm-human
Explanation:
Tapeworm, also known as Taenia solium is a parasitic nematode that gets into the human intestine, depriving humans of food nutrients. Its effects include diarrhoea, abdominal pains and general weakness of the human body.
Thus, the relationship of tapeworm and humans is parasitic because the tapeworm benefits at the human expense.
