Answer:
Living things can have a minimum of one cell
Explanation:
Living things can have a minimum of one cell; these are called unicellular organisms. Some examples of unicellular organisms: bacteria, algae (plants), some fungi, and protozoa

Answer:
The answer is
<h2>
![2.143 \times {10}^{18} \: \: atoms](https://tex.z-dn.net/?f=%202.143%20%5Ctimes%20%20%7B10%7D%5E%7B18%7D%20%20%5C%3A%20%20%5C%3A%20atoms)
</h2>
Explanation:
To find the number of atoms given the number of moles we use the formula
N = n × L
where
N is the number of entities
n is the number of moles
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
![n = 3.559 \times {10}^{ - 6} \: mol](https://tex.z-dn.net/?f=n%20%3D%203.559%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%206%7D%20%20%5C%3A%20mol)
Substitute the values into the above formula and solve
That's
<h3>
![N = 3.559 \times {10}^{ - 6} \times 6.02 \times {10}^{23} \\ = 2.1425 \times {10}^{18}](https://tex.z-dn.net/?f=N%20%20%3D%203.559%20%5Ctimes%20%20%7B10%7D%5E%7B%20-%206%7D%20%20%5Ctimes%206.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%20%5C%5C%20%20%3D%202.1425%20%5Ctimes%20%20%7B10%7D%5E%7B18%7D%20)
</h3>
We have the final answer as
<h3>
![N = 2.143 \times {10}^{18} \: \: atoms](https://tex.z-dn.net/?f=N%20%20%3D%202.143%20%5Ctimes%20%20%7B10%7D%5E%7B18%7D%20%20%5C%3A%20%20%5C%3A%20atoms)
</h3>
Hope this helps you
Simple!
Atomic number= number of protons AND number of electrons (in an atom)
Mass number= number of neutrons
