Why do scientists use the scientific method
Arte-miy333 [17]
The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?

Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.

Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.

If not, you reject your hypothesis.

Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.

Musya8 [376]

The connective tissue is among the four major classes of the tissue. It is the most widely distributed and the most abundant class of the tissues. However, the type of tissue in every organ varies. Composed of cells, fibers and matrix, this type of tissue is different in different organs of the body.

The variability in it's type is provided by the difference in the degree of the order of the cells, fibers, and the matrix. This variability contributes to the diversity of this tissue.

Hence, the blank can be filled with 'diversity'.

Molecular systematics might examine all of the following types of data EXCEPT ________.
Nadusha1986 [10]

Answer:

D) anatomical features

Explanation:

The molecular systematics uses the data on the molecular structures to establish evolutionary relationships between the organisms. Techniques of DNA, RNA, and amino acid sequencing are used to compare the macromolecules of organisms. These studies provide information about the degree of relatedness among organisms. The closely related species share a higher degree of similarities in the sequences of these macromolecules. However, this branch of science does not include information about the anatomical and structural features to establish evolutionary relationships.
