<span>Na is the chemical symbol for sodium. Na+ is formed when sodium loses an electron from its outer shell (the number of electrons and protons is now unbalanced, giving an overall positive charge) and becomes a sodium ion. Losing an electron happens when a metal reacts with a non metal.</span>
<span>Alleles are two different forms of single gene that are located in specific position on a specific chromosome. It can be classified into two allele pairs: homozygous and heterozygous. In homozygous, both alleles are the same whether they are both dominant or recessive; while in heterozygous, one allele is dominant and the other is recessive.</span>

Answer:</h2>
Blood Is A Heterogeneous mixture.
<h2>
Explanation:</h2>
Heterogeneous mixture is a mixture that is made up of different substance that remains physically separated which means the cell organelles (Red blood cells, white blood cells, platelets etc.)present in blood does not mix completely and hence get precipitated after kept still for a while.
There are three ways to identify a Heterogeneous mixture.
- It has chunks of stuff that you are able to see with your eyes.
- It appears cloudy(blur).
- After a while, the substance will separate into layers at settle at the bottom(gets precipitated).
Result: Blood is a Heterogeneous mixture
