Answer:
The correct answer is convergent evolution.
Explanation:
The wings of bats, butterflies, and most birds are the example of analogous structure. Analogous structures are the structures which are similar in appearance and function but have separate evolutionary origin.
They are similar superficially because they experienced a natural selection that evolved them to have that shape which helps them to fly. Analogous structures are produced due to convergent evolution.
Convergent evolution describes the presence of the same trait in unrelated species. Therefore the correct answer is convergent evolution.
Polyurethanase is an enzyme emitted by the microorganism so as to break polyurethane. Since the polymer is a significant wellspring of energy for the life form, it should be separated all together for etpum"s development.
Further details
Polyurethane
It is a polymer made out of organic units and carbamate links join them. While most polyurethanes are thermosetting polymers that don't liquefy when warmed, thermoplastic polyurethanes are likewise accessible. Polyurethanes are available in numerous parts of present-day life. They present a class of polymers that have discovered a far-reaching use in the medical and mechanical fields. Polyurethanes can be found in items such as furniture, coatings, cement, constructional materials, paints, elastomers, filaments and paddings. Polyurethane ought to be curtailed to PUR in consistence with authority German and International benchmarks.
Polyurethanase
It can be defined as such an enzyme which is secreted by microbes and used for the breakdown of polyurethane. In this breakdown process energy is released that is utilized by microorganisms.
Bio-degradation of Polyurethane
In spite of their microbial obstruction, polyurethane is attacked by microscopic organisms however the component to explain its bio-degradation is unknown. There are reports from microscopic organisms and parasites that are equipped for the breakdown of polyurethane yet the examinations about the proteins that assault the plastic are centered around bacterial compounds as it were. The enzyme is of sort esterase and protease for the most part since these chemicals are unspecific and can perceive a few regions in the polyurethane particle and hydrolyze it.

Answer:
did you already get the answer or you still need help
Answer:
A
Explanation:
The correct answer would be <u>option A</u> - GUA-CAU-ACC
<em>Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible</em>
<em>For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.</em>
<em>For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.</em>
Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC
