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:
i think its D
Explanation:
Because homeostasis is to maintain the internal enviroment of an organsism body constant .
organs responsible for homeostasis :
lungs: keep the concentration of carbondioxide and oxygen constant
skin: regulates the body temperature
kidney: regulates the concentration of water and urea
liver : regulates blood sugar level
I cannot tell whether this is multiple choice but the most likely explanation is adaptation. Evolution.

Answer:
order of least damaging is b, a, c and d
Explanation:
The 4 kinds of point mutations here present different consequences after a change of a single base pair. The silent point mutation is the least damaging because the alteration of the nucleotide does not implies on a different codon. Missense and nonsense point mutations will imply on a change of a entire different codon and a change of a entire codon to a stop codon, respectively. The missense could be a less aggressive mutation than a nonsense because the codon change may affect only in a small proportion of the entire protein, but the nonsense can be very aggressive by making the protein smaller than it is. The frameshift can cause severe modifications on the whole final protein because almost every codon might code for a different aminoacid leading to a whole new protein.
