Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating β-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains. Golden rice was developed to help cope with vitamin A deficiency, a problem that prevails in developing countries, affecting millions (Underwood, 2000; UNICEF, 2000). Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.

The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of β-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice results in Pale Yellow color.

We will rewrite the formula as an equation.

2K + 2Cr + 7O = 0

The zero comes from there being no overall charge on the compound.

Each oxidation number is represented by the element's symbol.

Since this compound is not a peroxide or superoxide, the oxidation value for O is -2

K being in group 1 has a +1 charge and therefore has an oxidation number of K is +1

Now, by putting known values in we have:

2(+1) + 2(Cr) + 7(-2) = 0

2 + 2Cr -14 = 0

2Cr = +12

Cr = +6.

The submerged portion of the ice on melting shrinks a little in volume. so the level of water goes down a little.But this is just made up by the water added by the melting of upper portion. Addition is equal to the Shrinkage. Hence level is unchanged.
