Answer:
Humans must decrease the harmful impact they have on earth or else the human population could go extinct forever. One way to do this is to inform the people on climate change and its effects. Recycling, using metal straws, carpooling, cleaning up beaches, pulling unncessary plugs in your house to reduce electricity usage, and doing so much more can help reduce the risk of climate change and help the world become a much healthier and stable place for humans, plants, animals, and the environment.
Explanation:
Answer: White blood cells form to fight off cell infections.
Explanation:
1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.
2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.
