<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 AND Explanation:
A steroid is an organic macromolecule that is biologically active with four rings arranged in a specific molecular configuration. Steroids are important components of cell membranes which alter membrane fluidity and act as signaling molecules. The two main types of steroids are corticosteroids and androgenic steroids like testosterone and estradiol.

Explanation:
our water pipes, and the led in some water sources.
Trenches are geological feature is most common at oceanic-continental convergent boundaries.
Explanation:
Usually, the oceanic plate, because it is denser, becomes subducted underneath the continental plate. The enormous stress of the two colliding plates causes the plates to warp abit downwards along the boundary causing a trench to form that stretches the boundary.
As the oceanic plate gets subducted and ‘dives’ into the mantle, it begins to melt into magma. Usually, due to the enormous stress along the boundary, fissures develop on teh continental plate along teh boundary. The magma rises through these fissures and erupts at the surface. Several mountains form long the boundary forming another signature geological feature of convergent boundary which is volcanic arc mountains.
