Answer:

X is the quantity value

Explanation:

To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.

The best classification for this new species is Animalia.

According to the six kingdom classification given by Carl Woese, all organisms are divided into 6 kingdoms.

1) Archaebacteria

2) Eubacteria

3) Protista

4) Fungi

5) Plantae

6) Animalia

As the newly discovered species is a multicellular (made up of more than one cell) organism.

Then it can only belong to Kingdom Fungi, Plantae and Animalia as the rest of the kingdoms like Archaebacteria, Eubacteria and Protista consist of unicellular organisms that are made up of only one type of cell.

Now this species is not autotrophic ( i.e. an organism that can get its own nutrition by the use of light, water, carbon dioxide, or other substances).

It means it is heterotrophic which means it can't get nutrition on its own.

Out of the Fungi, Plantae and Animalia , only fungi and Animalia kingdoms consist of heterotrophic organisms.

Now this species also does not contain chitin which is an important characteristics of Fungi.

So only option left is Animalia.

Hence, the best classification for this new species is Animalia.
