In a digestive tract, stomach is present at the distal end of the esophagus.
Stomach is a major part of digestive system and account for the digestion of protein. Stomach is a muscular organ, rich with secretary glands in it wall.
When food enters the stomach, it starts producing hydrochloric acid and two enzymes known as trypsin and chymotrypsin. These enzymes along with acid digest the protein component of the food.

Answer:
C) The Environment
Explanation:
This is because fossil fuels are carbon based and when burnt release that carbon store in the form of Carbon Dioxide and other gasses. These gasses such as carbon dioxide contribute to factors such as global warming, this is due to the enhanced greenhouse effect. The enhanced greenhouse effect is when the buildup of these gasses gets too high that it causes heat to build up. This happens because heat reflected and given off from the surface cannot escape are atmosphere and is reflected back.
Answer:
The correct statements are C The pH is accurate but the solution will have excess salt. D The pH is accurate but the concentration of Tris will be incorrect
Explanation:
As the pH is finally maintained at 7 the pH for the buffer solution will be accurate but excess salt will be produced due to use of Both NaOH and HCl to make up the to 7.
As more volume of water is required at final step to make up the volume the concentration of tris will be incorrect.
Answer: Nutrient enrichment had definitely impact animal life and leads to destruction of their natural habitat and curtails growth.
Explanation: The nutrients that are infused into the soil to enrich it can hamper a lot of on the surface level as well the organisms which are affected eventually.
The upstream of the nutrients reaching the coastal ecosystems which leads to
- poisoning of the shellfish
- toxic algae blooms
- destruction of the coral reefs
The impacts that it will have on
- trophic structure
- trophic interactions
- trophodynamics of phyto planktons, zooplankton and the benthic communities of the coastal ecosystems.
The prediction is gloomy as over the years it could lead to major shifts in animal life and have a larger impact on the environmental change that would be irreversible.
The nitrogen levels are peaking which is over-enrichment and more susceptible environments are bearing the and results show that now dead zones are being identified.
the oxygen levels get lowered resulting in the death of fish
