Both
Explanation:
Depends on what happened in that video. I would rewatch it and write about what the video said about flooding and relate it to the river. Could be an ice jam or something else slowing the flow of water suddenly opened up. A breaking dam? Flash floods from an abundance of rain. As the amount of water in the river increases, so does the flow rate. If the amount of water suddenly increases more than the river was used to/it could hold, it will flood.
Rewatch the video and see if this relates at all :)
The protein structures can be classified into four levels, namely the primary structure, secondary structure, tertiary structure, and quaternary structure. The primary structure is the simplest of all the structures. When all the hydrogen bonds are disrupted, the secondary, tertiary and the quaternary structures gets disrupted, which leads the protein to the most simplest structural form, that is the primary structure. In this structure, the a carbon atom is bonded to hydrogen atom, carboxyl group, amino group, and an 'R' group.
Answer:
Natural selection is the process through which populations of living organisms adapt and change. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
