A host cell infected by a virus will activate the adaptive immune response through white blood cells that are called as lymphocytes.
There are two types of responses through cells: antibody responses and cell mediated immune responses. These responses are occur by different types of classes of white blood cells those are called as B cells and T cells.
These T lymphocytes use chemical messenger to activate other immune system cells so that the adaptive immune system can activate. It detect the infected cells and destroy the cell.
Antibody is a blood protein that is produced in body in response to the specific antigen.

Answer:
<u>centrioles</u>
Explanation:
Centrioles are rod-like structures found in animals cells. The centrosome and centrioles proliferate and migrate to the opposite poles of the cell during cell division. Centrioles help in arranging the microtubules that separate chromosomes at the centromere during cell division to ensure each daughter cell receives the appropriate number of chromosomes.
There appears to still be a lot of debate within science over whether humans or climate change were primarily responsible for the extinction of many of the large mammals during this period. One hypothesis supporting the link to early human hunters is that large animals in sub-Saharan Africa co-evolved with humans as they learned how to use tools and developed ever more effective weapons. When early humans moved into Europe and Asia, taking with them their weapons and hunting skills, the populations of large animals in those areas were not accustomed to human hunting, and were therefore easy prey.
