How can toxic chemicals affect human immune, nervous, and endocrine systems?

Some toxic chemicals can make the body shut down and not function properly.

Explanation: Some gasses alter your cellular membrane like carbon monoxide or cyanide which affects your brain functions

The toxins reduce the amount of cells which are capable of suppressing the immune response. So multi-resistant strains, which produce very high levels of enterotoxin, becomes even more dangerous.

For endocrine system the chemicals are linked with developmental, reproductive, brain, immune, etc...

Hope it helps you.

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
