The abiotic environment consists of non-living things. So, rocks, temperature and water are part of the abiotic environment.
Answer:
The correct answer is - to protect the cells of these secretory glands from pepsin.
Explanation:
Pepsinogen is an inactive form of enzyme pepsin that is released by specific cells called chief cells within the gastric lining Releasing the inactive form of pepsin in preventing the auto-digestion of protective proteins and the cells of these secretory glands in the lining of the digestive tract.
Pepsinogen is activated by acidic pH to pepsin of the stomach lumen and the cell lining of the stomach is protected by mucus lining.
Ethanol is the fuel produced by fermenting crops.
A ground source heat pump takes advantage of the naturally occurring difference between the above-ground air temperature and the subsurface soil temperature to move heat in support of end uses such as space heating, space cooling (air conditioning), and even water heating. A ground source or geo exchange system consists of a heat pump connected to a series of buried pipes. One can install the pipes either in horizontal trenches just below the ground surface or in vertical boreholes that go several hundred feet below ground. The heat pump circulates a heat-conveying fluid, sometimes water, through the pipes to move heat from point to point.
this system works during the winter due to it being a sub-ground energy source.
Answer:
A "chain reaction" is a reaction that promotes or spreads the reaction. PCR rapidly makes a bunch of copies of a specific DNA sample and can "promote" the increase the amount of DNA.
