What does a high population density indicate? O The area is being overfished.

O The species is likely to face extinction.

O There is no other place for that species to live.

O Food supply is high and the number of predators low.

O Food supply is high and the number of predators low.

Explanation:

Population density is defined as the population living in per square mile/km.

High population density indicate that the people living in an area have high food supply and the number of predators low. Predators are responsible to control the population but due to high food supply and low predators, there will be no control in the population and no control in the feeding behavior of the population that leads to High population density.

Hence, the correct option is "Food supply is high and the number of predators low."

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

the answer is b.) hydrogen bonds between bases.
