Answer:
All organisms require sulfur as a macro-nutrient. (Ans. E)
Explanation:
Sulfur is necessary for all living things. It is taken up in the form of sulfate from the soil and sea water by the plants, and algae.
Sulfur is known as the essential nutrient for plant growth. Sulfur playing various important role in plants. About 90% of the sulfur is absorbed by the plants for the purpose of amino acids synthesis, known as the building blocks of proteins. Sulfur is important for the enzyme which is helping in the formation of the chlorophyll molecule. Sulfur is essential for the synthesis of oil crops.
In human body sulfur playing some essential role such as amino acid production which is converting into proteins and producing enzymes. Sulfur is important for insulin production, insulin allow the cells to use glucose as energy. Sulfur is found in most important antioxidant known as glutathione, which helping in the inhibition of oxidation of the other molecules and preventing from cell damage. Collagen provide skin strength and structure, sulfur is important for collagen synthesis as well.
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.
Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
Answer:
11)El ciclo del agua, conocido científicamente como ciclo hidrológico, se refiere al intercambio continuo de agua en la hidrosfera, entre la atmósfera, el agua del suelo, la superficie, el agua subterránea y las plantas. La ciencia que estudia el ciclo hidrológico es la hidrología.
12)Sabems que las etapas del ciclo hidrológico son las siguientes:
Evaporación
Condensación
Precipitación.
Las implicaciones que tienen para la vida cada una de las etapas son:
Evaporación, se reduce el nivel de los ríos, los lagos pequeños se seca, y se eleva la temperatura del ambiente.
Condensación, Es el proceso en el cual se forman las nubes, por lo que la luz solar disminuye.
Precipitación, produce nuevamente el aumento de los niveles de rios y lagos, y la disminución de la temperatura.
