The difference between diploid and haploid cells a duplicated chromosome consists of two sets of chromosomes.
The diploid cells consists of two sets of chromosomes whereas the haploid cells consists of one set of chromosomes. The haploid cells are formed by the process of meiosis and the diploid cell formed by the process of mitosis. 
In the higher organism, such as human the gametes are haploid and beside their all cells are diploid. The diploid cell when reproduce or increase their number through mitosis they form identical copy of its chromosomes. 
The examples of diploid cells are nerve cell, bone cell, etc. And the examples of haploid cell includes gametes.

Answer:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder 
Load 12 ul on the gel.
Explanation:
DNA Ladder concentration = 1000 ug/ml
1000 ug DNA in 1 ml DNA Ladder solution →    150 ng DNA = 0.15 ug DNA in..... 0.00015 ml = 0.15 ul DNA Ladder solution
6x DNA Loading Buffer → it has to be diluted by an equal volume 6 times (1 ul LB + 1 ul distilled H2O)
An appropriate volume to load on an average agarose gel is 12 ul, so:
2 ul Loading Buffer + 9.85 ul dH2O + 0.15 ul DNA Ladder = 12 ul
But since 0.15 ul is a very small volume and mistakes could be made while measuring it, let's make double:
4 ul Loading Buffer + 19.70 ul dH2O + 0.30 ul DNA Ladder = 24 ul
And load half of that solution (12 ul) on the gel.
