To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms.

1. NaCl:

Na  = 1 atom

Cl = 1 atom

2. CO₂

C = 1 atom

O = 2 atom

3. O₂

O = 2 atoms

4. C₆H₁₂O₆

C = 6 atoms

H = 12 atoms

O = 6 atoms  

For the second part;

1. 2NaCl

Na = 2 atoms

Cl = 2 atoms

2. 3CO₂

C = 3 atoms

O = 6 atoms

3. 4O₂

Answer:

The answer is when the cell express different genes.

A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation.

olga nikolaevna [1]

The correct answer is: the short half-life of edrophonium makes it impractical for long-term.

Edrophonium is used for the diagnostic of myasthenia gravis. In patient with myasthenia gravis, the body produces autoantibodies which inhibit nicotinic acetylcholine receptors in the neuromuscular junction. Edrophonium, on the other hand, is acetylcholinesterase inhibitor which blocks the effect of acetylcholinesterase enzymes (AcH stays in synaptic cleft).

Substitution for the edrophonium is pyridostigmine which is also acetylcholinesterase inhibitor but with long-term maintenance.
