As the inheritance is X-linked,recesson so for expression of muscular dystrophy in any given muscle,

enh1+ /enh1 + = Shows muscular dystrophy in heart (Homozygous for -)
enh2+/enh2+ = Shows no muscular dystrophy in arms (Homozygous for +)
enh3-/enh3+ = variabl or mosaic for muscular dystrophy in leg muscles (Hetrozygous for enh3)
Answer:
<h2>a) Evolution</h2><h2>

Answer:
The answer is - Biomass decreases as energy is transferred from one level to another.
Explanation:
The options are;
A. Chipmunks and insects can occupy the same niche.
B. As the number of bears in this community increases, the number of chipmunks will increase.
C. Insects are classified as omnivores in alpine meadow communities.
D. Biomass decreases as energy is transferred from one level to another
The answer is D. Biomass decreases as energy is transferred from one level to another
The energy pyramid being referred to is in the attachment below.
Biomass is an organic renewable source of energy derived from plants and animals. As animals at the lower trophic levels are consumed by animals at the higher trophic levels there is transfer of energy, however it is not all the energy that are transferred equally. As a result, at each trophic level there is decreased energy and biomass that is transferred from one level to the other.
