Answer:
Most liquids become monotonically denser when cooled from room temperature, but liquid water reaches its maximum density at approximately 4°C, below which it expands to become less dense as it is cooled further. To explain this density anomaly, several ideas have been proposed.
Explanation:
The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Answer:
Explanation: Hydropower is the generation of electricity from water through the construction of dams. it is a renewable energy source use over a wide range of environment. Construction of a waters storage project can raise the water level behind a dam from a few feet to several hundred feet by prevention water free flow called Inundation.
It leads to migration of human and other living organism such as fish and salmon. Salmon movement may be disoriented through the slower move of the water this leads to migration.
Fish moving around the dam coming in contact with turbines and the walls of the dam can become stressed, injured or die
vegetation and surrounding water it provide habitat for birds, waterfowl, and small and large mammals when hydroelectric project results in blockage of free-flowing river, the nesting, forage, and cover provided for the organism in these areas is temporarily or permanently lost.
