Answer:
Evolution in nature by natural selection only modifies the structures present in the ancestors and favors the better adapted structures.
Explanation:
An engineer can design the bones and muscles of the forelimbs of given organisms as per their needs and give rise to new unique structures for each of these organisms.
On the other hand, evolution in nature allows the modification of existing traits by the accumulation of variations. The adaptive variations in the traits are then favored by natural selection. Therefore, forelimbs of mammals such as horses, whales, and bats have evolved by modification of the forelimbs present in their common ancestors.
The limitation of modification of existing structures does not allow the formation of a completely new structure.

Answer:
The functions of nucleic acids have to do with the storage and expression of genetic information.
Explanation:
If it is a multiple choice. Try to find the coomb functions mentioned above.
The question is incomplete as it does not have the options which are:
aneuploids
allopolyploids
amphipolyploids
autopolyploids
Answer:
Autopolyploids
Explanation:
Autopolyploid refers to the ploidy condition in organisms in which the ploidy level of organism increases that is multiple set of a single chromosome is formed in tissues.
The autopolyploids condition is observed more frequently in the plants than the animals when the tissue cells divide. In the given question, the chromosome number increases or double that is from 18 to 36 to 54, 72 and 90. This shows that the ploidy level is increasing.
Thus, Autopolyploids is correct.
It would be A because textbooks aren't updated for years so he will likely never find it there
