<span>C. Melanoma, while it is less common than other skin cancers, is more likely to metastasize, or spread, without early intervention.
C. Once the cells that produce keratin die, a waterproof coating is formed, providing an additional barrier against infection.</span>
<h2>Natural selection</h2>
Explanation:
Natural selection acted up on gene,prevents the gene from acting as a reliable molecular clock
- Molecular clock measures the number of changes,or mutations,which accumulate in the gene sequences of different species over time;proves to be a valuable tool for estimating evolutionary timescales
- Natural selection is simply a concept of evolution where organisms with favorable traits are more likely to reproduce
- When natural selection is acted up on a gene governing the molecular clock then that gene won't be reliable because natural selection favors only the dominant gene
- The one's which are dominant and have desirable characteristics are favored under natural selection rest all species are eliminated whereas molecular clocks takes into the consideration the gene sequences of different species and the mutations occurring(irrespective of dominant or recessive species)
- Therefore natural selection will prevent the gene to work as reliable molecular clock whereas neutral mutation forms a base for molecular clocks

Answer:
Lion: Rich grasslands of East Africa to sands of Kalahari Desert, South Sahara to South Africa, excluding the Congo rain forest. They avoid dense forests because prey is scarce. Competition for Africa's grasslands by humans has drastically reduced the lions' range. Although lions were once widespread throughout much of Africa, Asia, Europe, and even prehistoric North and South America, they currently exist in the wild onl…
