<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.
The most common health problem associated with consumption of too much sodium increases blood pressure which can lead to heart disease. Other problems that result from too much salt intake are high cholesterol and heart attacks.
Answer:
Glacial striation is your answer

This is where you think of a question which you want to do an experiment on, and then later on conduct an experiment to answer that question.
