Nephrons are the filtering structures of the kidneys. The
kidneys contain millions and millions of these tiny filtering structures that
are responsible for cleaning the blood. Nephrons are responsible for removing
excess water, wastes, and other substances in the blood that are not needed by
the body. They also return necessary substances (e.g. sodium, potassium,
phosphorus) whenever the body runs low in supply.
If these nephrons are damaged, blood will not be properly
filtered. As a result, the kidney will have different diseases and this might
lead to kidney and multiple organ failure.

Answer:
response to stimuli / tropism
Explanation:
The plants and animals always respond to stimuli. It is an innate character of all living things. When a bright light falls on the eye, it closes immediately. This is responding to the stimuli. When someone touches the leaves of touch-me-not plants it closes its leaves due to the external stimuli.
The plants respond to the light. Because it does photosynthesis in the presence of light. Therefore, the leaves and branches of the plants always bend towards the light. This process is called phototropism.
Similarly, the roots of the plants move towards gravity under the ground. This is called geotropism.
Besides phototropism and geotropism, other types of stimuli are there - hydrotropism(response to the water), chemotropism(response to certain chemicals).
That's why the plants growing on the windowsill move towards outside where light comes.
<span>On the left, they drain into the renal vein
which in turn drains into the inferior vena cava. By contrast, all the
lumbar veins and hepatic veins usually drain directly into the inferior vena cava.</span>
The answer is the dendrites offer a big apparent area for links from other neurons. The dendrites are the main open or input areas and offer an enormous surface area for receiving signals from other neurons. They have spines appendages in which come to close interaction with synapses with other neurons.
Explanation:
When the barge enters the northern most part of the river, the southward current is 0.67 m/s. How will the barge be affected? The barge will move slower. The direction of the barge will change.
