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).

Answer:
An index fossil is also known as guide fossils or indicator fossil. They are fossils used to determine and identify geologic periods.
The main characteristics of an index fossil include :
1.It must be distinctive.
2.It must be widespread.
3. It must be abundant
4. It must be limited in geologic time.
Due to trends and studies of most fossil-bearing rocks being formed in the ocean, the major index fossils are mostly marine animal or plant organisms.
Answer: Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. ... Because animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria. hope this helps. Pls plz give me brainliest
