<span>Her data suggested that DNA is a helical structure that has two strands attached in the middle by the phosphate bases. That was the necessary information, needed to complete an accurate model of the structure of DNA. She also was the first one to announce that the phosphate units are located in the external part of the DNA and that the amount of water found in the molecule is in accordance with other parts of it.</span>
These would be the elements in row 2 the alkaline metals. Elements in a row usually share many qualities such as electon reactivity as well as similar characteristics like the fact that many alkaline metals are considered Cations, ions with positive charges. Some examples are beryllium and calcium.

The tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
<h3>What is the connective tissue?</h3>
Connective tissue is one of the types of primary tissues which has the function of supporting and integrating the rest of the cells since it is the tissue that gives a union of different tissue elements that make up the organs.
This tissue helps move nutrients to the cells they contain in order to give them nutrition, they can also transport other types of substances. Within the types of connective tissue are cartilage, adipose tissue and blood.
Therefore, we can confirm that the tissue that predominantly contains fibers that form a netlike support structure is the connective tissue.
