<span>Amino acids are the basic structural unit of all proteins. A 'free' amino acid (a single amino acid) always has:
an amino group -NH2,
a carboxyl group -COOH
a hydrogen -H
a chemical group or side chain -"R".
Since the amino acids (except glycine) have 4 different groups attached to the a-carbon, they are optically active stereoisomers (recall 23.101 Organic Chemistry) although only L-isomers are found in proteins.
At a neutral pH, both the amino and the carboxyl groups are ionised, giving what is termed the zwitterionic</span>

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.
Answer:
<em>the</em><em> </em><em>correct</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>urban</em><em> </em><em>heat</em><em> </em><em>island </em><em>effect</em><em>,</em><em> </em><em>cooler</em><em>.</em>
Explanation:
If you live in the city and head out to a rural town, the urban heat island effect suggests the rural area's temperature would be cooler.
