The answer is <span>b.reaction b releases more energy than reaction a releases.

The reaction a is an example of a chemical reaction while the reaction b is an example of a nuclear reaction. 
</span><span>Some main differences between the chemical and nuclear reactions are:
- The nuclear reaction releases more energy per gram.
- The nuclear reaction takes place in the nucleus of the atom, while in chemical reactions include electrons.
- In the nuclear reaction, part of the mass is converted into energy, which </span><span>violates the law of conservation of mass.
</span>
Therefore, the nuclear reaction (reaction b) will release more energy than the chemical reaction (reaction a).

A mutant bacterial cell has a defective aminoacyl synthetase that attaches a lysine to tRNAs with the anticodon AAA instead of t
solmaris [256]

Answer:

Proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.

Explanation:

Mutation may be defined as the sudden or heritable change in the genetic sequence of the organisms. The mutation can change the phenotype and genotype of the organisms.

The AAA codes for the lysine. The mutation attaches the anticodon AAA instead of normal phenylalanine. The aminonacids AAA will code for the lysine and no phenylalanine is observed in the cell as phenylalanine is coded by UUU and not by AAA.

Thus, the correct answer is option (b).
