Answer:
Endospores.
Explanation:
Microorganisms usually adapt to changes in their environment. One example of an extreme survival strategy employed by certain low G+C Gram-positive bacteria, generally of the Firmicute family, is the formation of endospores. They have a very peculiar structure that helps with this survival feature: an outer proteinaceous coat surrounding the spore provides much of the chemical and enzymatic resistance. Beneath the coat there is a very thick layer of specialized peptidoglycan called the cortex, which aids in resistance to high temperature. They are resistant to desiccation, lysozyme, ultraviolet and gamma radiation, chemical disinfectants, starvation AND temperature. So, in this experiment, it is probable that the boiled broth contained endospores, which survived this heating and then reactivated its metabolism.
When people are presented with a stimulus, the brain processes the information in two pathways. The "fast" pathway goes from the thalamus directly to the Amygdala.
Explanation:
Amygdala is the part of the emotional brain which is associated with the perception of fear, sadness, anger and agression.
Amygdala also plays a role in sexual activity and libido. The size of amygdala greatly reflects the rate of functional activity of the amygdala.
When the perception of stimulus follows fast pathway then the information travels directly from thalamus to amygdala and if it follows a slow pathway then the information passes from thalamus to cortex and then to the amygdala.
