This was to gain more support for Allied efforts in the Second World War to ensure their victory. By utilizing media, propaganda to support the war went into full swing as companies lent their efforts to achieve that end. They convinced people to buy war bonds as well as boost morale for the troops.
B. Blood components are continuously circulated through the blood vessels.
C. Blood components are continuously produced in the bone marrow.
D. Blood components are continuously digested by enzymes.
Answer: The correct answer is- C. Blood components are continuously produced in the bone marrow.
Formation of blood cells is a continuous process that occurs in the bone marrow ( a gelatinous, soft tissue present within bones) of adults.
This process is called as hematopoiesis, in which undifferentiated precursor cells ( also called stem cells) are developed and differentiated into particular blood cell type ( having specific function).
Thus, through this continuous process, all the components of blood can be replenished whenever they are required.
Therefore, when a person donates blood, he never run out of it.
The design attribute of water that allows for many unusual life-supporting properties is its unique structure and properties, such as high specific heat capacity, the ability to form hydrogen bonds and high heat of vaporization.
One key property is water's high specific heat capacity, which means it can absorb and release large amounts of heat without much change in temperature. This property helps regulate temperature in living organisms and prevents drastic temperature fluctuations.
Another important property is water's ability to form hydrogen bonds. These bonds give water its cohesion and surface tension, allowing water to stick to itself and other substances. This property is essential for the transport of nutrients and waste in biological systems, as well as the movement of water in plants through capillary action.
Additionally, water's high heat of vaporization enables efficient cooling through evaporation. This cooling mechanism is crucial for maintaining body temperature in animals and preventing overheating.

Answer:
B
Explanation:
Answer: The correct answer is nitrogen, calcium and phosphorus.
Explanation:
Elements are defined as the substances which are made out of same type of atoms. For Example: Hydrogen, Oxygen etc..
Human body is made up of various types of elements in which 6 are most abundant.
Almost 99% of the mass of human body is made up of mainly six elements. They are oxygen (O), carbon (C), hydrogen (H), nitrogen (N), calcium (Ca) and phosphorus (P).
About 0.85 % of mass of human body is composed of other 5 elements which are potassium (K), sulfur (S), sodium (Na), chlorine (Cl) and magnesium (Mg).
Hence, the correct answer is nitrogen, calcium and phosphorus.
