Hurricane Katrina.
It was the year 2005 when Hurricane Katrina marked its destruction in United States. The damaged caused by this was beyond repairable, there’s a reason why Katrina is marked as one of the most destructive hurricanes of all times in the history of U.S.
The impact hurricane Katrina had on aquatic ecosystem was terrifying. 150,000 acres of coastal wetlands was damaged. Approximately fifty sea turtles nests were lost. Oil, chemicals, and various other hazardous waste which released in the aquatic ecosystem resulted in the death of aquatic habitats. These are just a few examples of the impact the disastrous Katrina Hurricane had in our ecosystem.
I say, the answer to your question is C!
Answer:
Comparative genomics of the three groups
Explanation:
The comparative genomics of the three groups was used to determine their evolutionary distinctiveness. Comparative genomics is a powerful tool used to study evolutionary changes among organisms, it helps to identify gene similarities and differences among organisms.
Bacteria and archaea (formerly called archaebacteria) were considered much more closely related, but DNA sequence analysis showed numerous differences between the two groups, and further proved that archaea was closely related to eukarya than bacteria.
However, in 1970, Dr. Carl Woese and other scientists in a bid to determine the distinction between the three groups made use of the nucletide sequence of the ribosomal RNA as an evolutionary time clock.
It is widely known that the rRNA sequences; is present in all organisms, functions differently in various organisms, is involved in protein synthesis, can be align between two organisms and can change gradually over a long period, hence this made it a good tool to determine evolutionary distinctiveness.
The correct option is this: ANCESTRAL STATE RECONSTRUCTION SUGGESTING THAT THESE ANIMALS HAD OPSINS THAT WERE SHIFTED TOWARD THE RED.
Ancestral reconstruction is the extrapolation back in time from measured characteristics of individuals to their common ancestors. Opsins are a group of light sensitive proteins that are located in the photoreceptor cells of the retina of the eyes. Having opsin that were shifted toward the red colour will enable the animal to see very well in the night time, thus, the animal will be active during that period.
