Well to begin with this process is called genetic engineering, the scientists altered the DNA of the chickens instead of altering a protein already in the chickens because when you alter the DNA the offsprings of the chicken will will have the same qualities while if you only alter the protein already in that chicken only that chicken will be able to do the job
The DIRECT PHOSPORYLATION OF ADP BY CREATINE PHOSPHATE is the most inefficient pathway to regenerate atp during 30 minutes of light to moderate exercise.
Aerobic respiration is the pathway for regenerating atp that provides the majority of the energy used for muscle activities during 30 minutes of light to moderate exercises.
Viruses are made of one or more nuclei acid molecules surrounded by a coat protein or capsid. So the core of the virus will contain the viral genome. Some viruses' capsid maybe enclosed with an envelope derived from the host cell (the cell that the virus is infecting), and this envelope is also derived from the host cell membrane.
The mantle is made of a solid rocky substance.
