Biochemical tests and use of media allow physicians to identify
the type of bacteria causing a disease (such
as whether its gram+ or gram-) and use appropriate
antibiotic effective against the bacteria. Another clinical significance is to
determine the resistance of bacteria to antibiotics (this is conducted using susceptibility tests).
Binary fission is a type of asexual reproduction. This is when the cell divides into halves. So 1 cell would end up as 2 smaller cells.

Answer: Option B) is toxic to red blood cells.
Explanation:
Partial hydrolysis of lecithin by lecithinases (enzyme in black widow spiders and snakes venom) causes the removal of only one fatty acid to yield lysolecithins, which when subjected to the bloodstream by sting as a result of spider bite causes the rupture of red blood cells.
Thus, the mechanism is that it is toxic to red blood cells.
