Answer:
7
Explanation:
It is a neautral pH (pure water has a neautral pH).. Every enzyme works at an optimum pH and different enzymes work best at different pH.
Factors that determine the rate of stream erosion-
➡️ Rainfall (more rain more erosion). ✔️
➡️water velocity ✔️
➡️shape, size and depth of channel ✔️
➡️stream capacity to transport eroded material, and the nature of the material being transported✔️
➡️Gradient (Steepness or slope) ✔️
➡️Discharge (Amount of water carried at a given time) ✔️
➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️
➡️Slope (the steeper the slope the faster the water will flow) ✔️
➡️Geology (if the bedrock is a soft silt it will erode faster than granite).✔️
As technology makes advancements, it allows science to make advancements as well. But the inverse is also true, that scientific discovery also feeds technological ingenuity. So, science and technology advance together in a way that allows one to further their field so the other can further the other’s field and so forth
The fossil record is best at preserving visible changes in organisms through geologic time. This visible change is referred to as the evolutionary change.
<h3>The importance of fossil record</h3>
Fossils are the remains or impressions of a historical organisms which are preserved as a mold or in rocks due to pressure.
Fossil records are information made concerning these historical organisms about:
- the structure of the organisms,
- in what environment they lived, and
- the order in which they lived.
When these rocks are studied, visible changes in organisms through geologic time are observed which is that simple life forms gradually evolved into more complex ones.
Therefore, evolutionary change. is that visible changes noticed in fossil records.
