Answer:

Hair

Explanation:

The scientist predict that the contamination occurred several months ago. Under normal circumstances, most organisms would no longer have a trace of exposure in their urine or blood after 3 months.  If the organisms exposed to the radioactive three months ago and do not come near that area again within 3 months, the scientist wouldn't be able to identify it.

But, if that substance got into their hair, it will last way longer than that. Hair Analysis is very common to be used among forensic toxicologist to identify contamination that occurred months because of this.

How are decisions made about what products to manufacturers
nasty-shy [4]

Explanation:

Decisions regarding the product, price, promotion and distribution channels are decisions on the elements of the "marketing mix". It can be argued that product decisions are probably the most crucial as the product is the very epitome of marketing planning. Errors in product decisions are legion. These can include the imposition of a global standardised product where it is inapplicable, for example large horsepower tractors may be totally unsuitable for areas where small scale farming exists and where incomes are low; devolving decisions to affiliated countries which may let quality slip; and the attempt to sell products into a country without cognisance of cultural adaptation needs. The decision whether to sell globally standardised or adapted products is too simplistic for today's market place. Many product decisions lie between these two extremes. Cognisance has also to be taken of the stage in the international life cycle, the organisation's own product portfolio, its strengths and weaknesses and its global objectives. Unfortunately, most developing countries are in no position to compete on the world stage with many manufactured value-added products. Quality, or lack of it, is often the major letdown. As indicated earlier, most developing countries are likely to be exporting raw materials or basic and high value agricultural produce for some time to come.

Leya [2.2K]
I am not certain, but i think it increased the tension of the British and the colonists, as the British handed the colonists the bill for the french and Indian war in the form of taxes. I hope this helps!

Hatshy [7]

prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed

In this paragraph, those who were a part in crafting the Independence Declaration display their familiarity with 2d Treatise on Government: Of Civil Government of John Locke. sound judgment of particular circumstances-tells us that people should think long and hard before trying to overthrow any government, however evil.

Shkiper50 [21]

Answer:

This statement is <u>TRUE</u>.

Explanation:

Functional Magnetic Resonance Imaging (fMRI) measures brain activity in blood flow.  The blood flow concentrates or increases in the neural zone that is being used or activated.

This technique can be afected by certain factors such as noise from the scanner, also it can be afected by brain activity from sensations or thoughts. This is the reason why the subjects go through at least two different treatments in order to determine relative increases in the activation of each treatment.

NISA [10]

Answer:

According to Merton, Juan is most likely an A. conformist.

Explanation:

Merton suggested that there are 5 modes of adaptation into society, presented in the picture below.

Conformity refers to attaining something which is acceptable by society and by acceptable means. A conformed individual will pursue his/her acceptable dreams through acceptable ways because that is what <em>society considers as right. </em>

A clear example of conformity is the American Dream and in this case we could say Juan is most likely a conformist because he pursues his American Dream only by legitimate means (accepted by society).
