I think it's the 2nd one, the heart stops beating, the person doesn't respond, and the person isn't breathing normally. The pumping action of blood is disrupted so the heart can't pump blood to the brain, lungs, and other organs.
Since 1980, social marketing activities have been used to increase awareness on skin cancer prevention among Australians in an effort to solve this issue.
<h3>What causes the first signs of skin cancer?</h3>
a large area of brown with darker color flecks. a mole that is irregular in shape, size, texture, nor color. a tiny lesion that is red, pink, white, blue, and blue-black in some areas, with an uneven border. any lesion that hurts, itches, or burns
<h3>When skin cancer spreads, where does it generally start?</h3>
The tendency of melanoma and other cancer forms to migrate into adjacent lymph nodes first before entering the circulation and moving to distant parts of the body has long been recognized by medical professionals.

Answer:
Okay
Explanation:
Human topoisomerase I plays an important role in removing positive DNA supercoils that accumulate ahead of replication forks. It also is the target for camptothecin-based anticancer drugs that act by increasing levels of topoisomerase I-mediated DNA scission. Evidence suggests that cleavage events most likely to generate permanent genomic damage are those that occur ahead of DNA tracking systems. Therefore, it is important to characterize the ability of topoisomerase I to cleave positively supercoiled DNA. Results confirm that the human enzyme maintains higher levels of cleavage with positively as opposed to negatively supercoiled substrates in the absence or presence of anticancer drugs. Enhanced drug efficacy on positively supercoiled DNA is due primarily to an increase in baseline levels of cleavage. Sites of topoisomerase I-mediated DNA cleavage do not appear to be affected by supercoil geometry. However, rates of ligation are slower with positively supercoiled substrates. Finally, intercalators enhance topoisomerase I-mediated cleavage of negatively supercoiled substrates but not positively supercoiled or linear DNA. We suggest that these compounds act by altering the perceived topological state of the double helix, making underwound DNA appear to be overwound to the enzyme, and propose that these compounds be referred to as ‘topological poisons of topoisomerase I’
Answer:
A. Hair on the scalp
Explanation:
Please correct me if I am wrong :)
Well in the question it talked about head so of course the hair on the scalp.
