Answer:
The answer is B: All the muscle cells innervated by a single motor neurorn.
Explanation:
It is called a motor unit, all muscle fibers that are innervated by a motor neuron cell. A motor neuron cell can establish contact with up to 150 muscle fibrils, which when activated causes their simultaneous contraction, therefore, all the muscle fibers of a motor unit contract and relax at the same time.
What your brain says about the object's distance is Nothing - this is a visual pattern recognition test, not distance. The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.
- Nothing - this is a visual pattern recognition test, not distance.
<h3>How does the image arrive on the retina?</h3>
After the pupil, the image reaches the lens and is focused on the retina. The eye's lens produces an inverted image, and the brain converts it to the correct position. In the retina, more than one hundred million photoreceptor cells transform light waves into electrochemical impulses, which are decoded by the brain.
With this information, we can conclude that The size of the object and the distance it is from the observer determine the size of the image that forms on the retina.

Answer:
<u>Ethanol prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u>
Explanation:
Ethylene glycol is an organic compound usually used in antifreeze solutions, solvents and cleaners.
It is abused during self-destruction and accidental intakes.
<u>In the body, ethylene glycol is acted upon by alcohol dehydrogenase and is converted into glycolate and oxalate.</u>
Glycolate and oxalate are both nephrotoxic/ kidney damaging substances. Oxalate precipitates calcium oxalate stones in the kidney. Ethylene glycol poisoning also causes high anion gap metabolic acidosis.
In order to prevent ethylene glycol poisoning, the patient is infused with ethanol, ethanol <u>prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u> In this way, ethylene glycol is not metabolized and the formation of nephrotoxic substances is prevented. Alcohol dehydrogenase instead reacts with ethanol to form acetaldehyde.
It's true that patients have to provide an additional, specific authorization for training uses and disclosures of their information.
<h3>In which circumstances would a patient's written authorization to release PHI be required?</h3>
For any use or disclosure of protected health information that is not for treatment, payment, or health care operations or otherwise permitted or required by the privacy rule, a covered entity must seek the individual's written authorization.
<h3>What does the federal provision for "incidental uses and disclosures" mean? </h3>
Incidental uses and disclosures are not punishable if sufficient protections are in place and there is no carelessness.
- By refraining from using patients' names in public corridors and elevators, and by placing signs reminding personnel to respect patient confidentiality;
- By separating or locking file cabinets or record rooms.
