Answer:
Radiometric dating for the analysis of isotopes in the fossil.
Explanation:
Radiometric dating can be used to determine the precise age of a fossil by measuring isotoped decay within tge fossil or the surrounding rock in contact with it.
Answer: The temperature of the rainforest does not experience a drastic fall as in the case of the desert.
Explanation:
In the desert the average daytime temperature remains 100°F and that of the rainforest is 85°F. But average monthly temperatures are lower in the case of desert as compared to the rainforest although the vegetation cover is higher in rainforest as compared to desert so humidity is also more. During night in desert temperature drops to an average of 25°F whereas in rainforest during night temperature level does not drop much it drops to only 71°F. Therefore, the average monthly temperature on desert is lower than rainforest.
Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
option 2 seems appropriate for me!
Tachypnea, frequent desaturations, Tachycardia, retractions, nasal flaring, grunting, and etc.<span>
