Biochemical- apart of the second defense system
Answer:
D. DDT
Explanation:
DDT is highly persistent in the environment means that it break down very slowly in the environment. The half-life for DDT is from 2 to 15 years. Half-life is the time needed for the degradation of half of the compound. Persistent bio-accumulative toxic substances (PBTs) are chemicals that break down slowly in the environment and its accumulation in living organisms are toxic. Some PBTs are dispersed through air currents while some uses other environmental pathways, resulting in contamination of regions far from their points of origin.
Answer:
Population growth, lack of supplies
Explanation:
Urbanization can impact an area, especially population growth. People could be crowded, and that supplies could run out as it is an urbanized region.
Answer:
May alter the specificity for its substrate
Explanation:
The active site of an enzyme refers to the specific region of an enzyme that serves as the binding site for its one or more substrates. Binding of substrates to the active site of their enzymes is required for catalysis. Enzymes are highly specific for their substrates. Type of amino acids present in the active site of the enzymes and their interactions with substrates regulate the specificity of the enzyme. If a mutation substitutes the amino acid of the active site, it may increase or decrease the specificity of the enzyme for its substrate.
