What does the morphology of hair tell forensic scientists

1 answer:

3 0

Historically, hair has been considered class evidence because a hair specimen could not be identified with certainty as having originated from a particular person. A forensic scientist who studied the morphology (shape, form, and structure) of a hair specimen could testify as to the gross physical characteristics of the hair (color, degree of curl, etc.), its internal and external structural characteristics, the likely somatic region from which the hair originated (scalp, beard, pubic, axillary, etc.), and–at least for scalp hair, and often for pubic hair, the probable race of the person from whom the hair originated. But all of those are class characteristics rather than individual characteristics, so the most the forensic scientist can state based on morphological examination is that a hair specimen is “consistent with” or “similar in all respect to” another specimen.

A River Oaks Pools is trying to calculate the perimeter of the pool so they will know how many bricks to buy for the deck of the pool. Each square on the grid represents a square that is 3ft x 3ft. What is the perimeter of the pool?

Solution:

On the first row and last row, there are 7 numbers of squares. And on the 2nd to 5th row, there are 11 number of squares.

In getting for the perimeter of the area, we'll have to divide the regions.
Dividing the regions, we'll get three figures/planes :
2 rectangles with Length = 3ft x 4 number of squares and Width = 3ft x 2 number of squares
Thus, for the 2 rectangles,
Perimeter = 2(2L+2W) (times two since there are 2 rectangles)
Perimeter = 2(2(12)+2(6))
Perimeter = 72 ft

Another figure was formed is a square with a 21ft x 21ft
Perimeter = 4(21ft)
Perimeter = 84 ft

Add the two equivalent perimeters:

Total Perimeter = 72+84
Total Perimeter = 156 ft

A U.S. balance of trade surplus can result from

Anettt [7]

From the research that I have done, exports to the United States increases the country's balance of trade. Possibly creating a surplus of goods.

The correct answer would be an increase in exports to the United States

Here is a good example of what you are trying to understand.

If a country exports a greater value than it imports, it has a trade surplus, positive balance, or a "favorable balance", and conversely, if a country imports a greater value than it exports, it has a trade deficit, negative balance, "unfavorable balance", or, informally, a "trade gap". A positive balance adds to gross domestic product, while a negative balance subtracts from GDP.
