Red-green color blindness is a human x-linked recessive disorder. the normal allele, xb, is dominant to the mutant allele, xb. j
bazaltina [42]
Very interesting problem!

On first reading, it sounded impossible.  Tom has normal vision, and there are no male carriers for x-linked recessive disorders.  So the daughter can at best (or worst) be carrier of the disorder.

We are told that the daughter has the disorder, but the daughter can only be a carrier with genotype XBXb.

We are also told that Turner Syndrome, which is a disorder related to the x-chromosome.  Half of those affected have one of the x-chromosomes missing (monosomy), and some others have some cells with missing or deformed x-chromosomes (mosaicism).  Under these circumstances where the normal chromosome is missing, the X-linked recessive Xb allele will be expressed, hence even a carrier can express the red-green colour-blindness.

From the pedigree chart, we can deduce that the colour-blindness must be inherited from Jill, the mother.  Tom with normal vision cannot be a carrier because X-linked recessive disorders do not have male carriers.

The daughter's colour-blindness is derived from two sources,
1. inherited Xb allele from mother Jill
2. Turner syndrome that allowed the single allele to express colour-blindness.

Jill has a beaker. In this beaker there are two layers. The phone top layer is transparent with a yellow tint to it, and the bot
Margaret [11]

In the given case, most probably the top layer is of oil.  

As oil is not soluble in water, it will float on the top of the water surface, in the given case it is the beaker. The oil will always float on top of the water, as it is less dense in comparison to water. The water and oil do not mix as the molecules of water are more fascinated with each other than in comparison to the molecules of oil.  

As water is polar and oil is nonpolar, their molecules are not attracted to each other.

Deltas are built up by
frozen [14]
When a river reaches a lake or the sea the water slows down and loses the power to carry sediment . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.



so Ur answer is Deltas are build up by deposition
