Explanation: The shape of a river's stream bed affects the speed and eroding power of a river by influencing the amount of friction between the water flowing through the river and the stream bed below. Friction is the force that opposes the motion of one surface as it moves across another surface. In a river, there is friction between the flowing water and the stream bed beneath it. Where a river is deep, less water comes into contact with the stream bed, so there is less friction. The reduced friction means there is less opposition to the water's motion, so the river flows at a greater speed and has more kinetic energy for erosion. On the other hand, where a river is shallow, more water comes into contact with the stream bed, so there is more friction. The increased friction means there is more opposition to the water's motion, so the river flows at a lesser speed and has less kinetic energy for erosion. Also, the roughness of a stream bed covered with boulders and other obstacles causes the water to flow through the river in a turbulent fashion. This could cause the river to move slower in some cases or erode more in other cases.

They have a lot of blubber due to their habitat or the weather. I'm not sure if that's correct.
Explanation:
<span>Interphase is the first 3 processes where the cell matures, grows, and carries out its life functions. This process is followed by mitosis or the nuclear division and cytokinesis or the physical process where a parent cell is divided into two daughter cells. Every eukaryotic cell has a repeating set of occurrences which make up every cell’s life known as cell cycle. </span>When interphase come to an error before cell division, major problem can happen in the replication of DNA which can bring mutation. Mutation is a permanent damage of the DNA sequence of the genome due to the error in the process of DNA replication.<span> </span>
