Question

the table shows the elements found in dna nucleotide pieces. an x in the table indicates that the element is present in the nucleotide piece. a rectangle represents a nitrogenous base. which diagram correctly represents a nucleotide?

Explanation:

Step1: Recall nucleotide structure

A nucleotide consists of a phosphate group, a 5 - carbon sugar, and a nitrogenous base.

Step2: Analyze the components in the diagrams

The circle represents the phosphate group, the pentagon represents the sugar, and the rectangle represents the nitrogenous base. Based on the information in the table (not shown completely here but from general knowledge of nucleotide structure), the correct order is phosphate - sugar - nitrogenous base.

Answer:

The first diagram (where the circle representing phosphate is attached to the pentagon representing sugar which is attached to the rectangle representing nitrogenous base) is correct assuming the components in the table match the standard nucleotide components.
