Answer: DNA can be used to identify criminals with incredible accuracy when biological evidence exists.
Explanation:
In cases where a suspect is identified, a sample of that person's DNA can be compared to evidence from the crime scene. The results of this comparison may help establish whether the suspect committed the crime.
No Problem at all!
Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:

Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get

Putting values in this equation, we get:

Thus, the object is moving with a velocity of 1.33 m/s
Answer:
What is population?
A group of organisms of different species interacting with each other and the environment is called populatin.
The answer is; D
The plasticity of rock in the mantle and the convection currents in the region are responsible for tectonic plate movements. The hot molten rock from deep in the mantle rise and is replaced by the cooler rock at the upper mantle. These convections are similar to those of water in a boiling pot. As the tectonic plates move (as they are dragged by these convections) and collide, earthquakes are caused. In addition, at subductions zones (where two plates collide) there occurs high volcanic activity.
