Answer:
Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. ... The semipermeable membrane limits the diffusion of solutes in the water.

Answer:
a. M_D_
: 9/16 Black furred individuals
b. M__dd
: 3/16 gray furred individuals (1/16 MMdd + 2/16 Mmdd)
c. mmD_
: 3/16 Brow-furred individuals (1/16 mmDD + 2/16 mmDd)
d. mmdd: 1/16 gray furred individuals.
Explanation:
Available data:
- Dense pigment gene, D, codes for melanophilin.
- D allele dominant over d. 
- Gene M/m is responsible for the production of the pigment
- M is dominant over m
- If D is present, M/m is expressed
- If dd is present, M/m is not expressed  
- DDMM, DdMM, DDMm, DdMm --->Black fur
- DDmm, Ddmm ---> Brown fur
- ddMM, ddMm -----> Light gray fur
Cross: between two dihybrids

F1) 9/16 Black-furred individuals, D-M- (1/16 DDMM + 2/16 DDMm + 2/16    
                                                                  DdMM + 4/16 DdMm)
     3/16 Brown-furred individuals, D-mm ( 1/16 DDmm + 2/16 Ddmm)
     4/16 Gray-furred individuals, dd-- ( 1/16ddMM + 1/16 ddmm + 2/16 ddMm)
     
     
 
        
             
        
        
        
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.
