Read the following scenario to answer the following question. Avian influenza is a viral infection with few damaging effects tha
t naturally occurs in wild birds. However, avian influenza is highly contagious and can quickly kill domesticated birds. Some human influenza viruses are similar to the avian influenza. People infected with avian influenza develop typical flu symptoms (fever, cough, muscle aches). However, symptoms may become more severe and life-threatening. If avian influenza evolves into a form that is easily transmissible from person to person, a global pandemic of widespread human death might occur. Which cells would be active during an immune response to a viral infection
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.
Explanation:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.
Answer: The fundamental functional unit of muscle is called a sarcomere. One muscle may contain as many as 100,000 of the repeating sarcomere units. In the sarcomere, the myofilaments (thick filaments and thin filaments) are organized into parallel units.
