Answer:
Oxygen
Explanation:
When excessive minerals(N.P.K) and nutrient are released into the body of water from leaching and other sources,(detergents,fertilizers application,sewage etc )which leads to corresponding increase in the population of algae(algae boom)the condition is called Eutrophication.
This disrupts the oxygen cycle because,the increased algae population(algae boom) makes use of available oxygen in the habitat for respiration.With continue supply of the nutrients,the population continue to rise.The competition for oxygen with other fauna leads to shortage of available oxygen,and therefore death of these fauna,and later of the algae.
The decomposing bacteria,also used the fragment pf oxygen to decompose the algae and other dead fauna,further reducing the oxygen levels of the water,with increase in water pollution.
The history of the present illness is documented in the MEDICAL HISTORY section of the patient's record.
The medical history section contain information about all the diagnoses, medical care and treatment that the patient had received. These information help the current physician to have an idea of what has been going on concerning a patient's case in the past and he will documents his own observation in this section.
The answer to this question is that photosynthesis requires
carbon dioxide. Photosynthesis is the process where plants converts the light
from the sunlight into a chemical energy like oxygen and organic compounds.
Plants also use photosynthesis in order for the plants to make food.
Answer:
Explanation:
The biological or chemical change in the quality of water due to the presence of contaminants in water is called water pollution. Most of this contamination as on date is due to various human activities. In fact, humans are responsible for the mass deaths of whales and other aquatic organisms often swept ashore at different beaches in the world. There is an urgent need to look into the measures to control water pollution although a lot many efforts and schemes have already been announced by the Government in this regard. To make the students aware of this we have prepared short and long essays for students which shall inform them about water pollution and the means to minimise it.
Answer:
The given statement is True.
Explanation:
Scala media has endolymph as its constituent and endolymph is rich in Potassium ions (K+)
whereas
Scala tympani and scala vestibuli has in its composition Perilymph and Perilymph has sodium ions as their major constituent ions.
Therefore, scala media is Potassium ion rich while scala tympani and vestibuli are sodium ion rich.
