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)

Answer:

Exergonic reaction

Explanation:

A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.

An exergonic reaction owing to the negative free energy change is a spontaneous reaction.

The energy that is released in the exergonic reaction is usually observed in the form of heat and light.

The energy is released due to the breaking of the chemical bonds.

Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.
