DNA fingerprinting is far more conclusive because it is solid proof. It has evidence that a certain person was at a certain place at a particular time frame. Although most criminals do get asked to use the polygraph test, testing guilt I guess, measures only their heart rate. Which in a normal view many regular people would be nervous. There has been countless reports where murders can pass a polygraph test, but then be convicted of a crime due to proof of evidence from fingerprints. Humans are emotional beings, some can crack easily while some won't (through interrogation). So that's why it's key investigations use science to back up their crimes rather that try to measure someone's guilt.

There are 8,324,608 possible combinations of 23 chromosome pairs. As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.
Answer:
Exactly 4 people can go.
Explanation:
First, you subtract $169.50 from 14.50, which is $155
Then, you do 38.75 x 4, to find out how much money it would cost for the tickets.
Since 38.75 x 4 = $155, exactly 4 people can go to the amusement park.
Overproduction
Most species produce more offspring than can survive.
Competition
Since living space and food are limited, organisms must compete for the necessities.
Variation
Differences between individuals in a population.
Adaptations
Any kind of inherited trait that improves an organism's chances of survival.
Natural selection
The environment selects organisms with optimal traits to be the parents of the next generation.
Speciation
Over many generations, favorable adaptations accumulate and may result in a new species.
