Which of the following is the best example of a proper hypothesis? i think there is no effect on hearing if you listen to loud music for only three hours a day. grapes taste better than apples because grapes are sweeter. if different types of leaves are exposed to low temperatures, then they will change colors. water will flow faster through tightly packed soil than through loosely packed soil.

Hello!

I believe the answer is D) Water will flow faster through tightly packed soil than through loosely packed soil.

I hope it helps!

Option C is correct - If different types of leaves are exposed to low temperatures, then they will change colors.

Hypothesis can be described as a conditional description of the predicted connection between two or more variables under examination.

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."

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
