venlafaxine (brand name: Effexor) A medication used to treat depression (antidepressant) that affects chemical messengers within the brain. These chemical messengers are called neurotransmitters, and some examples are serotonin, dopamine, and norepinephrine.
They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environmen â¦ t is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents).
Their oxygen-free environments, and the observations that habitats of Archaebacteria can frequently be harsh (so harsh that bacteria and eukaryotic organisms such as humans cannot survive), supports the view that Archaebacteria were ones of the first life forms to evolve on Earth.
