Explanation:
Tall, perennial grasses and herds of grazing herbivores are inhabitants of tropical and temperate biomes and not desert biomes.
Deserts do not support the growth of perennial grasses and a sustained herd population.
- A desert is an arid landscape with very little to no rainfall through the years.
- Plants needs water to manufacture their food and live.
- Since this condition is absent, they cannot thrive in such biomes.
- Grazing herbivores needs a lot of grasses to satisfy their foraging and ruminant nature.
- Since grasses are lacking, they cannot survive.

Answer:
Thymine
Explanation:
Adenine is a Purines together with Guanine .
Purines always pair with Pyrimidines ; which are cyosine and Thymine.
This is a complementary base pairing that hold the two strands of DNA bases together by weak hydrogen bonds for flexibility and easily unwind during replication
Purines are larger in size beaxuae they have 2 ring structures while Pyrimidines aee smaller because of one ring structure.
Therefore two purines (Adenine and Guanine can not pair together;
It must be a Purines -Pyrimidines pairs.
Therefore Adenine must pair with Thymine and cyosine with Guanine
In RNA, Thymine are replaced with URACIL as Pyrimidines.
