It is true that rivers and streams are biodiverse ecosystems that are sensitive to change. Details about rivers and streams can be found below.
<h3>What is river and stream?</h3>
A river is a large and often winding stream which drains a land mass, carrying water down from higher areas to a lower point, oftentimes ending in another body of water, such as an ocean or in an inland sea.
On the other hand, a stream is a small river or a body of moving water confined by banks.
Rivers and streams are both freshwater ecosystems, hence, tend to respond to changes in their environment caused by anthropogenic activities.
Therefore, it is true that rivers and streams are biodiverse ecosystems that are sensitive to change.

The answer is a ...........................
Answer:
A: yes
Explanation:
B: Sample three is a mixture of the suspect and victims. Putting it simply, if you line up the victims DNA and remove it from sample 2 you are left with a sample of DNA that is identical to the suspects.
The <em>independent </em>variable is the variable that you change and control in your experiment. The <em>dependent</em> variable is the one you don't have control over and is affected by how the independent variable reacts.
For Example:
Let's say you're doing an experiment seeing how different sugars affect the density of cupcakes. The type of sugar you add would be the independent variable, because you are choosing it. The density would be the dependent variable, since it depends on the sugar used.
Answer:
Option-D
Explanation:
Casparian strips are the strips or band composed of a hydrophobic substance called the suberin which forms the ring-like structure in the endodermis of the vascular plants.
The Casparian strips are present around the vascular bundles in the endodermis to allow the uptake of the selective nutrients as the substance has to pass through the cell membrane before it enters the centre of the root or stele or vascular bundles.
The Casparian strips allow the movement of a substance through symplast mode only, therefore, is ensures the substance to pass through the cell membrane.
Thus, Option-D is correct.
