Which environment is most likely to be characterized by dry scrub with frequent fires?
Katyanochek1 [597]

Environments likely to be characterized by the presence of dry scrubs and frequent wildfires are those that lack the presence of rain and suffer high sunlight hours.

When referring to the terrestrial biomes that meet the characteristics described, we can include:

  • <u>Temperate grasslands</u>
  • <u>Cold deserts</u>

The temperate grassland/cold desert biomes have:

  • cold and dry winters
  • hot, dry summers
  • Extended sunlight hours

This biome is very dry, and the harsh weather makes it difficult for plants to grow, leading to their <em>dry scrub</em> characteristic. This biome also experiences frequent wildfires due to the <u>intense sunlight and lack of rain to which it is exposed.</u>

TCTCG and AGAGC are the perfect pair.

Option A

<h3><u>Explanation:</u></h3>

DNA is the genetic molecule of a living cell. The DNA stores genetic information of the species inside itself by means of particular pattern or sequence of nitrogen bases called as gene. The gene is comprised of the particular sequence of nitrogenous bases which are four in number - adenine, guanine, thymine and cytosine.

The nitrogen bases are present in both the strands of DNA and they have complementary relationship between them. The adenine forms hydrogen bonds with thymine and guanine pairs with cytosine.

Here the sequence of one strand is given as TCTCG. So according to the complementary pairing process, the opposite strand must have the sequence of AGAGC to maintain the structure.
