Molecular systematics might examine all of the following types of data except

a) proteins
b) dna sequences
c) amino acid sequences
d) anatomical features

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.

Anatomical features.

Explanation:

Molecular systematics may be defined as the use of the molecules to understand and deduce the evolutionary relationship. The classification of the organism is more easy by using the molecular systematics.

The plant evolutionary relationship can be made on the basis of the molecular systematics. The molecules that are used in the molecular systematics are proteins, amino acid, RNA  and DNA sequence. The anatomical features might involve in the morphology systematics.

Thus, the correct answer is option (D).

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
