A controversial issue of toxicology is the use of chemical additives in food.

Food additives are substances intentionally added to foods for the purpose of preserving, enhancing or modifying their physical, chemical, biological or sensory properties without impairing their nutritional value. However, it is necessary to control the use of these substances, as ingestion of these substances may pose health risks.

Additives are found in most processed foods, such as cookies, breakfast cereals, soft drinks, jellies, artificial juices, candies and a host of other foods in the diet of Brazilians, especially children.

Thus, its consumption should be controlled, as the health risk is confirmed by a sum of scientific studies. The three main ills associated with excessive consumption of these substances are cancer, food hypersensitivity and attention deficit hyperactivity disorder.

Some audiences are even more vulnerable to consumption, such as pregnant women, the elderly, people with little food and children under three years. In the case of children the attention should be greater because the digestive and urinary systems are not yet fully prepared to process these substances.

The more industrialized the product, the more chemical additives it will have. The ideal is to prepare fresh products at home. However, as is often not possible, it is important that you read the label and choose the products with the least additives.

City-state government was often conquered because they did not have enough resources to protect themselves

Explanation:

A city-state government is an independent autonomic political system which usually compromises just a single independent city which is governed by itself with sovereignty over its territory. The city-states like Greece, Italy, and Rome etc became very powerful.

The main reason for these city-states being conquered more was the accumulation of wealth and aristocracy in such states.

Heavy taxes, religion, slavery also lead to social unrest and conflicts among these city-states which made them weaker.  These internal conflicts also made them lose their resources and vulnerable to be conquered by other powerful empires.

With the increasing power of neighboring states, like in the case of Rome and Greece, the Romans became mightier than Greeks at one point and conquered the Greek city-states.

pav-90 [236]

Oceanic crust or a less solid piece of oceanic crust will subduct beneath continental crust. Earthquakes occur when the oceanic plate subducts into a trench. Volcanoes are created by the melting of mantle material.

<h3>What does oceanic crust mean?</h3>

The outermost part of the Earth's lithosphere, known as oceanic crust, is created at spreading centres on oceanic ridges that are found at divergent plate boundaries and is found beneath the oceans. The oceanic crust is roughly 4 miles (6 km) thick. Even without the sediment on top, it is made up of many layers.

<h3>What is a characteristic of oceanic crust?</h3>

Compared to continental crust, oceanic crust is both thinner and denser. This is because to the oceans' weight, which has compacted it beneath it. It is also much more recent than continental crust, typically existing within the last 200 million years.
