The heated sectional controversy between the North and the South reached new levels of intensity in the 1850s. Southerners and northerners grew ever more antagonistic as they debated the expansion of slavery in the West. The notorious confrontation between Representative Preston Brooks of South Carolina and Massachusetts senator Charles Sumner depicted in the image above (

The “Caning of Sumner” in May 1856 followed upon a speech given by Sumner two days earlier in which he condemned slavery in no uncertain terms, declaring: “[Admitting Kansas as a slave state] is the rape of a virgin territory, compelling it to the hateful embrace of slavery; and it may be clearly traced to a depraved longing for a new slave state, the hideous offspring of such a crime, in the hope of adding to the power of slavery in the national government.” Sumner criticized proslavery legislators, particularly attacking a fellow senator and relative of Preston Brooks. Brooks responded by beating Sumner with a cane, a thrashing that southerners celebrated as a manly defense of gentlemanly honor and their way of life. The episode highlights the violent clash between pro- and antislavery factions in the 1850s, a conflict that would eventually lead to the traumatic unraveling of American democracy and civil war.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
