These substances are all mutagens.
<h3>What purposes do mutagens serve?</h3>
Many mutagens are employed to kill cancer cells because they are very harmful to growing cells. Chemotherapy may involve the use of intercalating drugs like daunorubicin and doxorubicin as well as alkylating agents like cyclophosphamide and cisplatin.
<h3>What consequences do mutagens have?</h3>
Additionally, lesions that increase the number of single-stranded regions in the genome may be introduced by mutagens that rapidly degrade DNA, leading to even higher frequencies of recombination.
<h3>How do mutagens cause harm?</h3>
A mutagen is a substance that can permanently alter cells' genetic material, perhaps resulting in heritable genetic harm or cancer.

Answer:
Providing a controlled source of water vapour through which water can be vaporized into the plant envoirment.
Explanation:
Humidity ratio is the ratio of the mass of water in air to the mass of dry air. Humidity is needed in some conditions where the air is very dry. In a very dry air setting, there can be excess moisture loss from the plant surface, increasing the Humidity ratio can counter this effects and reduce excess moisture loss.
There are four major classes of biological macromolecules:
