The given statement is True.
The aim and objective of the environmental engineers are to reduce the influence of the land, which is being created on the environment itself. This is because of the attempts being made that the environment is kept in its natural form as much as possible, as any destruction on it may have implications for everyone associated with it.
Thus, this kind of engineers is attempting to determine the exact equilibrium between the developments of the land for human utilization and sustaining environment with least destruction.
Answer:
B)TAT becomes TAC
Explanation:
since thymine(T) pairs with adenine(A), thymine(T) is replaced with uracil(U) in the RNA and guanine(G) pairs with cytosine(C)
we can find the complementary codons for each strand
the codon for TAT is AUA which codes for methionine
the codon for TAC is AUG which also codes for methionine
that means the phenotype (methionine)remains unchanged for different genotypes(TAT and TAC)
