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.
The best answer would be the butterfly. Many insects go through different physical changes during growth. These insects include the butterfly. From being an egg it turned into a larva and grown into a caterpillar which later on become a butterfly.

Explanation:
Animals get energy from food. Plant related food takes the sun to grow, and other prey may get energy from plants which uses the sun to grow. If you have any questions, don't hesitate to ask!
Two things that Characterize the practice of science is empirical evidence and community consensus. Hope this helps.
Answer: Two smaller molecules join together after a water molecule is removed from between them. Energy is absorbed for bond formation: because energy is absorbed to make bonds, synthesis reactions are energy absorbing reactions.
