Hair plays an important role in our lives. The hair on our head keeps us warm and acts as a cushion for our skull. Hair appearance can also help form our identity and self-image, which makes hair loss very troubling.

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.
Explanation:
When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.
As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.
Thanks to its memory cells, the virus will remain much less time in the body.
Answer: 160 mm HgTherefore, the partial pressure of oxygen is: PO2 = (760 mm Hg) (0.21) = 160 mm Hg, while for carbon dioxide: PCO2 = (760 mm Hg) (0.0004) = 0.3 mm Hg.
