<u>Answer</u>: <em>Option 2</em> foreign antigens
<u>Explanation</u>:
<em>Antigens</em> are proteins that are found on the surface of a pathogen and <em>white blood cells </em>(leukocytes) are the cells of the immune system which helps fight infection and protect the body from foreign antigens.
Whenever a foreign antigen enters the body, a type of white blood cell called as the lymphocyte recognizes it and then produces antibodies against it, to generate an immune response.
So, <em>an immune response is primarily due to white blood cells recognizing foreign antigens.</em>
The correct answer is 6.46 W. This is how much power needed to do 648 joules of work in 100 seconds. This could be calculated using the formula P= E/t where P is power, E is joules, and t is time. So in this case, P = 648/100. So the answer is 6.46 W.
