Answer:

By 1900, Fingerprint was the evidence which was collected at crime scenes to help positively identify suspects by one particularly unique trait.  No two people can have the same type of fingerprints. It is a unique characteristic which is even not common among identical twins. Therefore, was considered as an important evidence for identification of suspects and linking them with the scene of offence. In 1904, the city of St.Louis, Missouri used fingerprint evidence for the first time for criminal identification.

hammer [34]
<span>When organisms are born in the wild, they tend to start developing an understanding of their surroundings based on their experiences. If an organism is transplanted to a different environment right after birth, it will develop the instincts to survive in that environment. A sudden change in its environment will result in the organism being out to place, possibly unable to cope with the selection pressures of its new environment. This will likely be the case with these guppies. This issue with transplantation is very real with animals born in captivity, which is why many are put through simulation exercises such as hunting and hearing the calls of predators, so that they may be able to survive in the wild, when transferred.</span>

The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that
dexar [7]

Answer:

The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions

Explanation:

The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.

The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in  shape there would be no life existed.

Thus, the correct answer would be - C)

A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

45.7 * 32.5 = P_{2} * 4.1

1485.25 = 4.1P_{2}

P_{2} = \frac {1485.25}{4.1}

P_{2} = 362.26

Final pressure, P2 = 362.26 kPa

Research by social scientists suggests that it takes ____ percent of the population of a community, country, or the world to bri
Lady bird [3.3K]

Answer:

<em>The correct option is B) 5-10%</em>

Explanation:

We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.
