Answer:
Gene therapy is a medical field which focuses on the utilization of the therapeutic delivery of nucleic acids into a patient's cells as a drug to treat disease.
The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.
The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.
And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization
Oxygen cycle The cycling of oxygen between the biotic and abiotic components of the environment (see biogeochemical cycle). ... In the process of respiration oxygen is taken in by living organisms and released into the atmosphere, combined with carbon, in the form of carbon dioxide.
The ciliated simple columnar epithelium is a tissue that would line the uterine tubes and function as a conveyor belt to help move a fertilized egg toward the uterus. The ciliated columnar epithelium transfers mucus and constituents through cilia and is originate in the upper respiratory area the fallopian tubes, the uterus, and principal part of the spinal cord. It is the main objective of contamination for common cold illnesses.
