Explanation:

Rice is global staple food. It is mostly affordable by the poor and peasant farmer wordwilde.Vitamin A is an important vitamin for good eye sight and also for boosting the  immunity.

This useful vitamin is  present in eggs, cheese and liver. Which are expensive for poor families Some small quantity are produced as carotene found in carrot. However, a precursor of Vitamin A called Pro-vitamin A carotenoids  is present in the part of rice called the Aleurone layer.

However this part of the rice is not in the endosperm thus the vitamin are washed way during processing of white rice .Although this is present in brown rice. Basically, the energy storage in most crop seeds is stored in the endosperm. Thus the vitamin in the rice are not stored are therefore not imbibe during consumption.

Therefore in order to incorporate  carotenoid into the endosperm to avoid been wasted, Daffodil was used. The genes for the transcription of carotene in daffodils and from  particular soil bacteria called Pantoea Anantis were extracted, to transfer carotenoid into the rice endosperm. This is called the Golden rice,, because the rice appear golden from the incorporation of the carotenoid into the endosperm though genetic engineering. This appear orange from the carotene pigment present in the endosperm.

Thus from the consumption of the rice ,poor family could imbibe vitamin A into their diet.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
