Answer:
Magma
Explanation:
This rock is made of cooled magma
In this case, researchers observed a trade-off between the ability to tolerate harsh dry conditions and the ability to colonize deeper water. This type of trade-off can increase the fitness of only one phenotypic trait.
An evolutionary trade-off can be defined as an evolutionary mechanism where a trait can increase its adaptive fitness in the detriment of decreased adaptive fitness in another phenotypic trait.
In trade-offs, the evolutionary adaptive processes cannot optimize a given trait without compromising another.
A well-known example of an evolutionary trade-off is the balance between the number of eggs that a bird can produce in a determined clutch.

Answer:
Three reading frames
Explanation:
Translation of mRNA always happen in one direction from the 5' end to the 3' end of the RNA strand.
Reading frame refers to the grouping of three consecutive bases to form a codon that can constitute an amino acid.
There are six possible reading frames in any nucleotide sequence.
Three from the 3' to the 5' end and three possible reading frames from the 5' to the 3' end.
As mentioned earlier, translation in mRNA happens in one direction therefore the three possible reading frames are;
- 5'- C AGA UCU AAU GCU UAU CGG AU-3'.
- 5'- CA GAU CUA AUG CUU AUC GGA U-3'.
- 5'- CAG AUC UAA UGC UUA UCG GAU-3'.
