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.

Bacteriophages most frequently have which sort of morphology, when bacterial genes are transmitted from one bacterium to another by a virus.
<h3>What does a bacteriophage look like morphologically?</h3>
The best method for examining the morphology of bacteriophages is electron microscopy. It has a polyhedral head, a short neck and collar, and a straight tail. It is tadpole-shaped. The head is 950 x 650 in size and has a bipyramidal hexagonal form. A membrane (capsid) that is about 35 thick encloses the contents of the head.
<h3>What kind of bacteriophage is most typical?</h3>
Assphages are a large and common family of tailed bacteriophages that are thought to infect bacteria belonging to the phylum Bacteroidales. Members of this viral family have never been isolated in culture and are still poorly understood despite being present in up to 50% of people and accounting for up to 90% of human gut viromes.
