Answer;
DNA replication is semi-conservative.
The meselson-stahl experiment supported the hypothesis that DNA replication is semi-conservative.

Explanation;
The Meselson-Stahl experiment was an experiment by Meselson and Stahl that proved that the semi-conservative model by Watson and Crick was correct.
DNA replication is semi-conservative in the sense that the new helices formed after replication contain, one new DNA strand and one old strand from the parent DNA molecule.

A. what is hard water? why is the presence of hard water often considered a negative thing? (3 points)

Anna35 [415]

Hard water contains mineral ions basically the calcium and magnesium ions.

The presence of hard water often considered a negative thing as it is associated with a number of issues related to plumbing, water storage as well as cleaning and maintenance.

Hard water leads to clogged pipes due to the deposition of ions on the surface of water conducting pipes. This hindrance also degrades the quality of equipment used for water storage and heating e.g. geysers.

The hardness of water can either be temporary or permanent depending on the type of ions present in it. Temporary hard water contains calcium and magnesium ions whereas Permanent hard water contains anions like the sulfate ion.
