timofeeve [1]4 years ago
6 0

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.

The use of hypovirulence to manage chestnut blight in Europe is an example of
WARRIOR [948]

Answer:

option c. viroid control

Explanation:

The chestnut tree in Europe is infected by a fungus called <em>Cryphonectria parasitica </em>that<em> </em>causes a disease called chestnut blight. The disease is controlled by a biological control method called hypovirulence.

The hypovirulence is a virus that attacks the fungal pathogen (<em>Cryphonectria parasitica </em><em>)</em> of chestnut tree. This fungal virus decreases the ability of fungal pathogen to cause chestnut blight disease. This technique prevents the chestnut plant after huge destruction of it in Europe.

The pathogen that have virus is introduced naturally over the plant. This reduces the infection and allows the natural growth of trees. Thus, option C is correct.

These patches are excessive multiplication of lymphoid nodules within the lower portions of the small intestines.The occurrence of this abnormal cell division may prevent the linings of the intestines to perform its normal functions.
