Answer:
Composite resins are less brittle than ceramics but have greater wear at the edges so may not last as long as a bonded ceramic restoration. Composite resins are used when restoring teeth with minimal biting forces and can also be used as intermediate restorations when planning full mouth restorative cases.

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.
The appropriate cardiorespiratory endurance guideline set by the American College of Sports Medicine for the Frequency of a workout is 20-60 minutes.
All healthy adults between the ages of 17 and 65 are advised to engage in vigorous-intensity aerobic activity for at least 20 minutes three days a week, or moderate-intensity aerobic activity for at least 30 minutes five days a week, according to the American College of Sports Medicine's cardiorespiratory endurance guidelines. According to the most recent edition of physical activity guidelines for Americans, to get the maximum health advantages from physical exercise, children and adolescents aged 6 to 17 must engage in at least 60 minutes of moderate-intensity movement each day. Thus, the duration of 20-60 minutes is considered best for aerobic exercise.
