Answer:

(a) 21% of the human genome is comprised of G.

(b) 29% of the human genome is comprised of T.

(c) 29% of the human genome is comprised of A.

Explanation:

According to Chargaff's rule, a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G), and G pairs with C and A pairs with T.

If 21% of the genome contains C, then 21% also contains G.

Therefore 21% + 21% = 42% of the genome is comprised of G+C.

The other 58% is comprised of A+T, and because they pair with each other, 29% will correspond to A and 29% will correspond to T,

Almost all coal used today was produced during the Carboniferous period from dead animals in the swamps.
Ann [662]

Answer:

False

Explanation:

Almost all coal that is used today has its origins in the Carboniferous period. The Carboniferous period was a warm and wet one, with the majority of the land being swampy and covered with dense rainforests of ancient tree species. By the end of this period, the climate quickly changed, resulting int he collapse of the rainforests. As the trees were dying out, they were falling in the swamps, quickly being covered by the mud, so remaining largely preserved. Over time they got exposed to higher pressure and temperatures as they were getting deeper into the crust, eventually resulting in the formation of the coal.

<h3>How do both mars and earth share characterstics?</h3>
  • Both the planets have the same area of dry land. This is because two-thirds of the area of Earth's surface is covered with oceans but water is absent on Mars.
  • Both Mars and Earth exhibit temperature and atmosphere.
  • The geological processes on Mars and Earth are common for example formation of volcanoes, canyons and impact basins.
  • Mars exhibits rings but the earth does not.
  • Earth exhibit distinct seasons but Mars do not due to reducing and hot atmospheric condition.

Thus, these are the similarity between mars and earth.
