Q1. I had black mold growing on roof and ceiling in my home for yrs, from a leaking roof. Contractor who fixed it and never said anything about mold up in attic. I have moved since but my whole family has symptoms that are very strange, even dogs do. We have headaches daily, itch constantly what is really weird is all our hair turned in to this wirey frizzy uncontrollable mess and we have all this like hair or fiber substance coming off our bodies all the time. It’s so bad you can see this stuff in air sometimes. Is it mold related?

Q2. In humans, examine the transport of gases (oxygen and carbon dioxide) by blood and exchange of these gases between the blood and cells of the body. Comprise in the discussion cellular and fluid composition of blood.
