The Strange Case of BeriBeri

In 1887 a strange nerve disease attacked the people in the Dutch East Indies.
The disease was beriberi. Symptoms of the disease included weakness and
loss of appetite, victims often died of heart failure. Scientists thought the
disease might be caused by bacteria. They injected chickens with bacteria from
the blood of patients with beriberi. The injected chickens became sick.
However, so did a group of chickens that were not injected with bacteria.
One of the scientists, Dr. Eijkman, noticed something. Before the experiment,
all the chickens had eaten whole-grain rice, but during the experiment, the
chickens were fed polished rice. Dr. Eijkman researched this interesting case
and found that polished rice lacked thiamine, a vitamin necessary for good
health.

1. State the Problem

2. What was the hypothesis?

3. How was the hypothesis tested?

4. Should the hypothesis be supported or rejected based on the experiment?

5. What should be the new hypothesis and how would you test it

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.

do yall know the answer?
