You are snorkeling out in the ocean, when you come out across this sight. You cannot decide if the smaller fish is a parasite or a mutualist of the bigger fish. You decide to both do more observations on these two fish species in the wild, and to bring them back into the lab for experiments. Describe the observations you would make & an experiment you could do to test if this is a mutualism or a parasitism.

The analysis comprise in watch the conduct of each gathering of fishes. Subjectively, we can mention objective facts of the swimming examples of every creature, on the off chance that they assault one another or if the pass on. Be that as it may, this investigation will be founded on quantitative outcomes. We will observe during multi month of the quantity of fishes in each gathering that still alive. Obviously, we will give the standard states of nourishment, oxygen and light to each gathering.  

We need to determinate if the two species can get by their own without the nearness of the other one. Our hypothesis would be: If both kind of fishes have a mutual relationship, the two gatherings (1 and 2) will lessen the quantity of people continuously. On the off chance that the relationship is parasitic, one of the two gatherings will have less number of people toward the month's end.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
