The shelf life for feed that is fortified with non-stabilized vitamin c is approximately 3 months before it oxidizes and losses its antioxidant qualities. It does not expire the moment the packaging is damaged and the product is exposed to light or air.
Answer:
The correct answer is a tRNA brings over the correct amino acid by using the anticodon to match to mRNA during translation
Explanation:
tRNA or Transfer RNA play an important role during the translation process.tRNA contain anticodon that interracts with the codon of mRNA molecule with the help of Ribosome to bring the amino acid to its own acceptor arm. The amino that is brought to acceptor arm of tRNA is specific for the codon present in mRNA.
tRNA then moves to the P site and a new tRNA bind to the A site of ribosome and brings a new amino acid that form peptide bond with previously generated amino acid. Then process continue untill the tRNA recognizes a termination or nonsense codon

Answer:
Post reproductive isolation → Hybrid sterility
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
Postzygotic mechanisms or barriers include
- Hybrid inviability,
- Hybrid sterility,
- Hybrid decreased viability or fertility,
- Cytoplasmic interactions.
In the exposed example, it seems that the mountains separating the frogs´ populations made a place for the development of postzygotic barriers, specifically hybrid sterility. Frogs from one population get to mate and produce offspring with the frogs of the other population, but their progeny is sterile.
Answer:
During formation of the luteum.
