Answer:
This question is incomplete as it lacks options, the options are:
A) What is the radius of each particle of the substance?
B) Does the substance contain more than one type of atom?
C) Was a chemical reaction necessary to create the substance?
D) What is the electrical charge of the particles of the substance?
The answer is B
Explanation:
In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.
According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?
- If the answer is yes, the substance is a COMPOUND
- If the answer is no, the substance is an ELEMENT.

Answer:
The correct answer is "mutations to homologous genes".
Explanation:
The missing options of this question are:
A) morphology.
B) the pattern of embryological development.
C) biochemical pathways.
D) habitat and lifestyle choices.
E) mutations to homologous genes.
The correct answer is option E) "mutations to homologous genes".
Modern cladograms do not use physical characteristics to establish evolutionary similarities among species. Modern cladograms are constructed from evidence from molecular systematics based on similarities in mutations to homologous genes. The more similar are the homologous genes, the less different their genetic sequences are, and are considered more closely related in their evolutionary tree.
