C. Semiconservative replication
Explanation:
Semiconservative replication is a mechanism of replication. Semiconservative model of replication states that in daughter cell, with new double-stranded DNA (cell after replication and mitosis) one strand is from the original template molecule while other is newly synthesized.
This is possible thanks to complementary pairing in DNA (each original strand of double-helix DNA is used as a template for the synthesis of the new strand).
Answer:
Different organs in the body work together to make organs systems. The different organ systems are interrelated to ensure the normal functioning of the body. The survival of an organism depends on the co-related activities of the organ system.
For example, the respiratory system and the circulatory system work together to provide oxygen to all the body cells and to eliminate carbon dioxide from the body. The circulatory system transports oxygen from the lungs to other parts of the body and transports carbon dioxide from the body parts to the lungs.
The nutrients required by the blood and other organs of organ systems are provided by the blood of the circulatory system.
The blood of the circulatory system is filtered by the kidneys of the urinary system.
