which of the following is the most basic building block of matter? A.
cell B.
crystal C.
gene D.
atom

a cell is the correct answer

The answers would be:

1. Electron cloud

2. Electrons, Electrons, Electrons

3. Nucleus, nucleus

4. Protons, protons

5. Neutrons, Neutrons

6. Direct, direct.

7. Inverse, inverse

8. No relationship, no relationship

9. Experimental control

10. Controlled variables

Here is more about the question:

An atom has 3 subatomic particles:

Proton: positively charged particles

Electron: Negatively charged particles

Neutrons: Neutrally charged particles

The nucleus is made up of the protons and neutrons, while the electrons are found outside, within the electron cloud.

Electrons are very important in bonding. It is also heavily involved in electricity. Electricity is the flow of electrons through a conductor.

Relationships in a graph:

For direct relationships, you just need to remember, when one goes up, the other one goes up too.

Inverse relationships on the other hand, when one goes up the other goes down.

If no change occurs, then we can say that there is no relationship.

OC) They are the basic building blocks of matter.

They are made up of atoms of 2 or more elements that are

chemically combined.

Explanation:

OC) They are the basic building blocks of matter.

They are made up of atoms of 2 or more elements that are

chemically combined.

Explanation:

Option (d) is the correct answer.

Explanation:

A compound is defined as the substance in which only different atoms chemically combine together in a fixed ratio by mass.

For example, NaCl, HCl, , etc are all compounds.

Compounds are also pure substances like elements as they can be broken down into their constituent particles.

Whereas substances that are made up of only one type of atom are known as elements.

Thus, we can conclude that the most accurate description of compounds is that they are made up of atoms of 2 or more elements that are chemically combined.
