The motor unit is composed of the motor neuron and innervated fibers, which are the ones that contract. 1) motor unit 2) contract.
<h3>
What is the motor unit?</h3>
The<u> motor unit</u> is the association between the motor neuron and a group of fibers from the muscle.
A single muscle is composed of several motor units. But the fibers involved in only one motor unit are just a little part of the whole muscle mass, meaning this is the part that will contract.
The motor unit is the basic unit from which the CNS controls motion.
Before contraction, there must be a stimulus that is received by receptors.
The CNA sends a message to respond to the stimulus.
The message is transmitted, by motor neurons, as chemical signals -neurotransmitters- which are received by the muscle fibers.
When the muscle cells receive this information, a cascade of events occurs that produce the local contraction of these fibers.

Answer:
One paragraph i hope this helps.
Explanation:
From synthetic compounds to electrical hardware, research centers procure a wide cluster of wellbeing risks, which is the reason it is so imperative to comprehend the significant of lab security. By getting comfortable with the research center you're working in and continually following legitimate security systems, you can assist with forestalling or kill risks.
L.S. is brought to the emergency department for management of acute mushroom poisoning. Her respirations are slow and shallow, and she is nonresponsive. She is admitted to the critical care unit to be closely monitored for the development of respiratory failure and renal failure, which often accompany mushroom poisoning. Her urine output is decreased to about 20 ml/hr. Her laboratory values are serum K+ = 5.7 mEq/L; arterial blood gases (ABGs): pH = 7.13, PaCO2 = 56 mm Hg, PaO2 = 89 mm Hg, HCO3- = 18 mEq/L.
1A. What is the most likely cause of L.S.’s potassium imbalance? Explain the role of the kidney in potassium excretion
Answer: L.S. is experiencing a intrarenal acute renal failure in the category of tubular necrosis (due to ingested mushroom toxins).
The kidneys helps to maintain the electrolyte concentrations by filtering electrolytes and water from blood, routing some to the blood, and excreting any excess into the urine.
Therefore, the kidneys help to maintain a balance between daily consumption and excretion of electrolytes and water.
Explanation:
Daily variations in potassium excretion are controlled mainly by changes in secretion in distal and collecting tubules.
• Maintaining potassium balance depends primarily on renal excretion which is determined by:
• the rate of potassium filtration
• the rate of potassium reabsorption by the tubules o the rate of potassium secretion by the tubules
i.e. About 65% the filtered potassium is reabsorbed the proximal tubule and another 25% to 30% in the ascending loop of Henle.
Natural gas and petroleum, upon burning, produce carbon dioxide. If you look at methane and the such, these hydrocarbons react with oxygen forming carbon dioxide and water.
The claim that petroleum is not carbon based is downright wrong. Methane is a hydrocarbon, and petroleum is a combination of complex hydrocarbons with varying chains of carbon atoms, some having 6 carbon atoms, others 60, giving it the viscous feel.
Coal deposits may be found in many places, but are still scarce and poses A LOT of risks, for example children were often harmed during the Industrial Revolution as a result of breathing in too much of the dirty air. Even now, coal mining is not without risk.
The only right answer then is the last one, where nuclear power does not produce air pollution. It relies on nuclear fission, where upon the splitting of uranium atoms they release energy, and this energy is harnessed by scientists for the betterment of all.
