When you are collecting DNA, you could be looking for a few different things. A few examples could be skin cells, strands of hair, or possibly even a fingernail. Anything that comes from a person, including blood or saliva can be potential DNA that could help investigators to link a person back to a crime.

Investigators do not need a warrant for analyzing crime scenes due to the fact of the dangers of the fire. You must work quickly because accelerants tend to evaporate within days, sometimes hours. It is also important to note that finding the origin of the fire is very important, to make sure it won't be reignited. Debris is usually cleaned away quickly to ensure health and safety issues.

The point of origin of a fire is the lowest point, since fire burns upwards.

High explosive: Ignite almost instantly, like dynamite and TNT. Two different types are primary and secondary.

<em>Primary: easily ignited, very sensitive to heat and friction. often used to ignite other explosives. </em>

<em>Secondary: much less sensitive to heat and friction, might be ignited using other explosive materials. TNT and dynamite are both secondary. </em>

Low explosive: decompose slowly and include black and smokeless powder. They are the most common type of explosives, and are readily available.

Answer:

  • <em><u>Measurement of the amount of variation of the species in a given area. </u></em>

Explanation:

<em>Bio</em> preffix means life. Thus, literally, biodiversity means how diverse is the life. This is, how many different organisms an ecosystem or biome has.

Thus, biodiverstiy, although more complex than just that, is a measure of the number of species that live in a region.

The biome with most species than any other, this is the biome with the greatest biodiversity, is the tropical rainforest biome, which are located near the equator. As you can imagine, a large number of different plants, animals, and microorganisms live in these forests, making them the regions with greatest biodiversity on the planet.

What was the average speed of the truck for this trip?
Goshia [24]

Answer:

31.67 mph

Explanation:

To calculate the average speed of the truck, we must first obtain the total distance travelled by the truck followed by the total time taken for the truck to cover the distance travelled.

The following data were obtained from the question include:

Total distance) = 30 + 45 + 50 + 65 = 190 miles

Total time = 1 + 2 +1 +2 = 6 hours

Average speed =.?

Average speed = Total distance / Total time

Average speed = 190 /6

Average speed = 31.67 mph

Therefore, the average speed of the truck is 31.67 mph

Could someone explain what oxidation numbers are and what these questions are asking of me?
Oxana [17]

The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation of an atom in a chemical compound.

<u>Explanation:</u>

The oxidation number of an atom is the charge that atom would have if the compound was composed of ions. 1. The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. The oxidation number of simple ions is equal to the charge on the ion.

The oxidation number of a mono atomic ion equals the charge of the ion. The oxidation number of H is +1, but it is -1 in when combined with less electro negative elements. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides. The oxidation number of a Group 1 element in a compound is +1.
