Answer:
The correct answer is A)
To limit the potential flooding damage that could result if an earthquake happens and the dam spills over
Explanation:
According to the text, seismic risks are very high for dams in that region. One of the reasons is that some of the dams were built many years ago when civil engineers didn't have information about what an earthquake could do to dams.
Citing an occurrence that happened in 1899 as an example where thousands of people were killed as a result of a failed dam, it is feared that should same reoccur, the loss may be more because about 300,000 people occupy the flood zone along the Alameda Creek below the dam.

Answer:
Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.
Explanation:
Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.
The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.
