<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.
Answer:
Mass
Explanation:
Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.
The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
