Answer:
Explanation:
Cell specialization is also called cell differentiation. Through this process, specialized cells form from the unspecialized cells. Then many cells are formed and determined to form specialized functions.
The stem cells are the unspecialized cells which form a different kind of specialized cells.
The muscle cells, nerve cells, sperm cells, red blood cells are specialized cells perform different specialized functions. All these cells arise from stem cells. The nerve cells receive impulse, muscle cells can contract, etc.
There are certain inductive signaling genes that send the signal to the differentiated cells. These signaling molecules are called ligands. These ligands move to another cell to produce specialized cells. In other words, there are some transcription factors and genes responsible for such cell differentiation and the formation of specialized cells.
Another example is zygote, which is an unspecialized cell. This is also a totipotent cell that has the potentiality to reproduce different cells.

Answer:
4 Fe + 3 O₂ → 2 Fe₂O₃
Explanation:
Let's start with the oxygen.
Reactants - 2
Products - 3
What number do 2 and 3 have in common? 6.
Put a 3 in the reactants and a 2 in the products to balance the oxygen.
Fe + 3 O₂ → 2 Fe₂O₃
Now let's look at the iron.
Reactants - 1
Products - 4
Put a 4 in the reactants to balance the iron.
4 Fe + 3 O₂ → 2 Fe₂O₃
The equation is balanced. Hope that helps.
