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.

<span>Basal Body Temperature (BBT) is the body temperature upon waking up
or when a person is at rest. After ovulation, a woman’s BBT rises because of increase in
progesterone level. BBT swill stay high throughout the post-ovulation phase and
until the following cycle. If there is pregnancy, BBT will stay high.</span>
Answer:
C. It is a male with atleast one dominant allele
Explanation:
In the given pedigree, the two normal parents of the generation I have one daughter with the attached earlobe. Since the trait is recessive, the daughter should be homozygous recessive to express the trait. The genotype of the daughter (shaded circle in generation II) is "aa". To have a daughter with "aa" genotype, both the parents should have one copy of "a" allele. So, the genotype of both parents is "Aa".
In generation II, individual A is non-shaded square. Squares represent males in a pedigree. Since its not shaded, it does not have attached earlobe. Both the parents are heterozygous dominant for attached earlobes (Aa x Aa = 1/4 AA : 1/2 Aa : 1/4 aa). The genotype of this individual may be AA or Aa.
