To calculate the mean all you have to do is add all the numbers from the data set and then divide the answer between the number of data set. For example, if you data set is 2,3,4,5,6,then you add 2+3+4+5+6=20 Now you divide 20 between the total number of data, so from 2 to 6 you have 5 numbers. You divide 20/5 and that that is equal to 4.
Since you did not post your data set I can not tell you exactly the answer but you can use this information to walk you through it.
Answer:
D.Predation
Explanation:
Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.
Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.
The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.
The answer to this question is exocytosis! This process allows particles to go through a small hole in the cell wall to enter other parts of your body! I hope this helped
