The human circulatory system consists of a pumping organ X that pumps Y throughout the body. The Z are small vessels that carry the blood within them and transport it throughout the body. Identify X, Y and Z.
Assertion (A): Water is reabsorbed in the descending loop of Henle.
Reason (R): The ascending loop of Henle is completely impermeable to water.
The cellular gaseous waste produced during the process of respiration in plants is .......................................
The breakdown of pyruvate to give carbon dioxide, water and energy takes place in ...............................
The leaves of the plant first prepare food “A” by photosynthesis. Excess of food “A” later gets converted into food “B”. What are “A” and “B”?
P are organisms that cannot locomote. These organisms use Q and R to prepare glucose as a food with the help of a green coloured pigment S present in the cell organelle T of the leaves, in presence of light. This process is called U. The excess of food prepared by these organisms is stored in the form of V which gives a bluish-black colouration in reaction with iodine solution.
Identify P,Q,R,S,T,U,V from the given options.
The table given below shows the differentiating points between aerobic respiration and anaerobic respiration:
|Aerobic Respiration||Anaerobic Respiration|
|1. It requires oxygen.||1. It does not require oxygen.|
|2. Incomplete breakdown of glucose takes place.||2. Complete breakdown of glucose takes place.|
|3. 38 ATP are produced.||3. 2 ATP are produced.|
|4. Ethanol carbon dioxide are the byproducts.||4. Carbon dioxide and water are the byproducts.|
