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.

Natalie had random hand movements when she was two months old. when she was six months old, she used to grab a block with her whole hand. now at the age of ten months, she can grasp the same block with her thumb and forefinger. this sequence of growth in her hand and finger movements is according to the pattern.

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.
