Answer:Argon Gas maybe?
Explanation:Just got it right lol
<h2>DNA Mutations</h2>
Explanation:
<em> (A) A base-pair deletion</em>
- <em>Insertion or deletion brings about a frame shift that changes the perusing of consequent codons</em> and, hence, adjusts the whole amino acid arrangement that follows the transformation, additions and cancellations are normally more harmful than a substitution in which just <em>a solitary amino corrosive is modified </em>
- DNA changes brought about by mutagens may hurt cells and cause certain illnesses,<em> for example, malignancy</em>
- <em>Instances of mutagens incorporate radioactive substances, x-beams, bright radiation, and certain synthetic compounds</em>
<em>A circadian rhythm /sɜːrˈkeɪdiən/ is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in plants, animals, fungi, and cyanobacteria.</em>
the correct answer is a)I only
Earth had essentially no atmosphere when it originated 4.6 billion years ago from a heated mixture of gases and minerals. The ground had melted on it.
An atmosphere developed when Earth cooled, primarily from gases released by volcanoes. It contained methane, hydrogen sulfide, and ten to 200 times as much carbon dioxide as the atmosphere we are surrounded by today. The Earth's surface began to cool and solidify after roughly 500 million years, allowing water to accumulate there. Although life on Earth continued to develop and diversify, such periods of expansion and development were halted by mass extinctions, in which many of the planet's major life forms were either entirely or partially wiped out and many others were freshly established. Such catastrophic extinction episodes are attributed to asteroids impacts, climate change, volcanic eruptions, etc. Dinosaurs were also wiped out in one such event. The largest problem the Earth is currently experiencing is climate change brought on by human activity. Although human activities may exterminate some species from the world, the planet will undoubtedly recover and return to its natural balance as it has for millions of years. However, the sun will ultimately wipe out Earth, as predicted by scientists. The Sun will lose its structural integrity and enlarge in volume as it ages and eventually runs out of the fuel that keeps it going—hydrogen—which will cause it to burn everything in its path, including life on Earth. In the end, the Sun would perish, leaving the Solar System permanently in the dark.
