My best educated guess would be more of earth's freshwater is found underground (aquifers) than in lakes
Answer:
Biosphere is affected directly by the change in the hydrosphere in a natural way for example: the rain that falls from cloud and again the cloud forms by the evaporation of water from the ocean.
Explanation:
- Rain (hydrosphere) falls into the atmosphere from clouds forming the river water and streams in the biosphere.
- Plants and animals are dependent over this rain water for their survival in the form of drinking water for their growth.
- Water then evaporates from the rivers and oceans forming clouds when water vapor condenses.
- In this way living organism are highly affected by the natural process occurred in the hydrosphere.
The statement is true. Digestion of food molecules in the digestive system in the gastrointestinal tract does not require coupling of ATP hydrolysis; but instead requires enzymes that speed up the spontaneous reaction. Enzyme digest specific food substrates at different parts of the digestive system until the final useful products of these enzymatic reactions are absorbed to the body metabolism.
Most cell types are very permeable to water. an exception is cells of the distal nephron, which can be either impermeable or permeable, depending upon the absence or presence of aquaporins.
Answer: The body maintains homeostasis by positive and negative feedback mechanism.
Explanation:
The body maintains the internal temperature and metabolism with respect to change in environment.
In case the temperature outside is very cold and the body starts shivering by the movement of skeletal muscles, this is done to maintain the temperature inside body. This is positive feedback.
When the temperature inside the body is maintained, then body stops shivering. This is negative feedback.
This is how the body maintains homeostasis.
