VLD [36.1K]

Answer:

See the answer below.

Explanation:

Antibiotic-producing bacteria are generally known to have a mechanism that enables them to be resistant to their own antibiotics. The mechanism that enables them to be resistant to their own antibiotic depends largely on the mode of action of the antibiotic substance.  

Some of the popular mechanisms used by bacteria to counter their own antibiotic substance include a mutation in the target gene, production of enzymes that inactivate the antibiotic compounds, or efflux of the compounds.

<u>In the case of </u><u><em>Streptomyces griseus</em></u><u>, the inactivity of streptomycin has been linked with the production of a phosphatase inhibitor that prevents streptomycin from getting access to the target site. Hence, the organism is not harmed by its own antibiotic.</u>

How are active faults and inactive faults similar
ICE Princess25 [194]
Active faults are structure along which we expect displacement to occur. By definition, since a shallow earthquake is a process that produces displacement across a fault, all shallow earthquakes occur on active faults. Inactive faults are structures that we can identify, but which do no have earthquakes.

The ball with a mass of 1.5 kilograms is tied to the end of
Hunter-Best [27]

Solve the

potential energy at point B


PE = mgh


Where m is

the mass


G is the

acceleration due to gravity 9.8 m/s2


H is the height


PE = ( 1.5

kg) ( 9.8 m/s2) (0.5 m)


PE = 7.35 J



Solve the

velocity using the


KE = 0.5mv^2


Where ke is

the kinetic energy


M is the

mass


V is the

velocity


Since all

energy is converted to KE


So KE = PE



7.35 = 0.53(1.5)

v^2


V = 3.13 m/s
