Chimeric mice are generated where approximately 50% of the cells in the animal are genetically MHC class I-deficient. The other 50% are deficient for the herpes virus receptor, HVEM, but do express MHC class I molecules. When these mice are infected with herpesvirus by intraperitoneal injection, a robust virus-specific CD8 T cell response is detected at day 7 post-infection in the spleens of the infected mice.

Answer:
The Z lines and H- zone shortens during the muscle contraction.
Explanation:
Sarcomere is the area between the two Z lines. The Z- lines are present in the centre of I - band and H - zone is present in the A - band. The actin filaments which are thin filaments present in I- band and contracts, slide over the myosin filament during contraction.
The I - band, H- zones are became shortens as they are thin than the A- band. It is anisotropic band having thick myosin filaments. They are not flexible and remain in its constant shape during the muscle contraction.
After the muscle contraction, the A- band and the H- zone comes to their original shape. In other words, the sarcomere shortens and comes back during muscle contraction, and relaxation.
Answer:
some forest are really affected by activity because polluted they put trash in the water and they never clean it up and the animal life are getting sick and they are dying this does affect diversity because animals can die if we have polluted waters
Explanation:
Answer:
the signals have different frequency
Explanation:
The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.
