UNO [17]

Answer:

1000 mM

Explanation:

Using V = -60 mV㏒₁₀[K/K'] where V = membrane potential = -60 mV, K = intracellular concentration = unknown and K' = extracellular concentration = 100 mM

So, V = -60 mV㏒₁₀[K/K']

-60  mV = -60 mV㏒₁₀[K/K']

dividing both sides by -60mV, we have

-60  mV/-60 mV = ㏒₁₀[K/K']

㏒₁₀[K/K'] = 1

taking antilogarithm of both sides, we have

[K/K']  = 10¹

multiplying both sides by K', we have

K = 10K'

K = 10 × 100 mM

K = 1000 mM

So, the intracellular Cl- concentration is 1000 mM

Will give brainliest to first correct answer.<br><br> Explain how the superbug was created.
jolli1 [7]

Answer:

A superbug refers to a germ that has formed resistance to multiple drugs that once treated the infection caused by the germ. The term “superbug” was developed by the media. While any germ may become a superbug, bacterial and fungal strains that routinely infect humans, animals, and crops are most likely to do so.

Superbugs are strains of bacteria that are resistant to several types of antibiotics. ... And the overuse and misuse of antibiotics helps to create drug-resistant bacteria. Here's how that might happen. When used properly, antibiotics can help destroy disease-causing bacteria.
