Methicillin-resistant-staphylococcus-aureus (MRSA) infection is caused by the bacteria called staphylococcus aureus, which leads to skin infections in mild form and respiratory diseases in severe form.
Hospital-Acquired MRSA – is associated with infections that are caused due to exposure to hospital or nursing home environments.The infection can be caught through direct contact or contaminated hands. Sometimes touching used surgical instruments or infected bedsheets can also pass on the infection leading to severe pneumonia or blood infections. Hence, people hospitalized for longer durations, live in nursing homes, or visit hospitals regularly without protection are prone to get a staph infection.Hospital acquired MRSA often causes severe symptoms compared to community-acquired MRSA due to prolonged exposure to bacteria.learn more about MRSA here: https://brainly.com/question/8190489

Why is there no output from the photo-electric cell when the RLG is not moved?
There is no output from the photoelectric cell when the RLG isn't moved because the laser beams are 180 degrees out of phase.
What is a photoelectric cell?A photoelectric cell is also known as phototube and it can be defined as an electronic tube (device) that is fitted with a photosensitive cathode, which emits electrons when illuminated, as well as an anode that collects the emitted electrons.
Based on scientific research and experiment, we can logically deduce that there is no output from the photoelectric cell when the ring laser gyro (RLG) isn't moved because the laser beams are 180 degrees out of phase.

Neuron's permeability to K during the falling phase of an action potential - A. Neuron's permeability to Na during the falling phase of an action potential B. Neuron's permeability to K during the falling phase of an action potential a. A and B are equal. b. A is greater than B. c. B is greater than A.
The permeability of the neuron membrane to Na and K differs with the stages of action potential as follows:
A is greater than BA is greater than BB is greater than AWhat is an action potential?An action potential is a sudden change in the voltage across the membrane of a resting neuron resulting in transmission of impulse.
An action potential results in variation of neuronal membrane to sodium and potassium ions.
A. Resting neuron's permeability to K >>> B. Resting neuron's permeability to Na
Thus, A is greater than B.A. Neuron's permeability to Na during the rising phase of an action potential >>> B. Neuron's permeability to K during the rising phase of an action potential.
Thus, A is greater than B.A. Neuron's permeability to Na during the falling phase of an action potential <<< B. Neuron's permeability to K during the falling phase of an action potential.
B is greater than A.Therefore, the permeability of the neuron membrane to Na and K differs with the stages of action potential.
