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).
It is likely that bacteria evolved to dwell inthese harsh conditions early on and have retained the abil-ity to exploit these areas as the rest of the atmosphere haschanged. 34.1 Bacteria are the smallest and most numerous organisms.
