Stays content is the answer
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.

A list of the cell fibers from largest to smallest would read:
1. microtubules – is a microscopic tubular structure that is present in numbers in the cytoplasm of cells. These are usually aggregated to form complex structures.
<span>2. intermediate filaments – are cytoskeletal components that is usually found in the cells of vertebrate species and </span>other organisms like plants, fungi, unicellular organisms.
3. <span>Microfilaments – are filamentous structures that can be found in the cytoplasm of eukaryotic cells and it will form part of the </span>cytoskeletons<span>. They are composed primarily of polymers of actin. But in cells, they usually interact with other proteins.</span>
Answer:
Artifical Selection OR Cross Pollination
Explanation:
If white roses and red roses are cross-bred by scientists, it would be artifical selection. If they were crossed in nature, it is called crossed pollination.
