Does friction enhance movement? True or false
Answer:
False. Friction does not enhance movement.
Friction is the force that is generated when two objects "rub" on each other.
For example, it's hard to push an object on a rug, but it's easier to push an object on hardwood floor. This is because the rug creates more friction when the object rubs against it, thus slowing it down.
So, the statement is false.
Hope this helps.
Answer: False
Explanation:
Friction always in opposite direction to movement
. Mr. Sanchez comes to the desk to check out after seeing the provider. When Laura tells him that his bill is $95, he complains that he only saw the provider for 10 minutes. The fee is in accordance with evaluation and management guidelines. Explain the fees to Mr. Sanchez.
What Mr. Sanchez must understand is that the fee is not a variable rate depending on the minutes that the consultation lasts, but on the contrary it is a fixed rate, that is:
an immutable value that responds to the use of the medical service that does not respond to the duration of it.In this way, nothing else matters than the result of the service, that is, the evacuation of the medical consultation. Thus, if this was done in 5, 10 or 60 minutes, only the result of it will be considered when establishing the rate.

1. In which of the following situations may 10 access be used?
O An extremity with signs of infection
O An extremity with signs of a crush injury
O An extremity with a previous unsuccessful 10 attempt
O An extremity with slow cap refill time
Answer:
O An extremity with slow cap refill time
Explanation:
Intraosseous access can be used in patients, children inclusive, to gain vascular access when they are in shock due to sickness or injury. IO cannulation rapidly delivers drugs and fluid to a marrow venous plexus that is noncollapsible. This is especially important if the patient is in shock and is to be resuscitated fast. Slow or prolonged capillary refill time is an indication of shock.
This option is used when other measures of delivering drugs, for example, the intravenous route are unavailable. The distal femur, the proximal tibia under the growth plate, the distal tibia above the medial malleolus are common sites where intraosseous access can be administered.

Explanation:
A 31-year-old man completes a half-iron triathlon and immediately submits several blood samples for a research protocol on the effects of vigorous exercise on lipids. His triglycerides (TG) are found to elevated at 232 mg/dL. He consumed almost no fat during the race and ate a carbohydrate-rich breakfast. How do you explain his result
Answer:
The increase in triglycerides can be a result of a diet with excess carbohydrates.
Explanation:
As we saw in the question presented above, the man ate a carbohydrate-rich breakfast. Since he does strenuous exercise, it's likely that all of his meals are high in carbohydrates, so he has a lot of body energy. However, this can generate excess carbohydrate in his body and this excess can stimulate insulin, which in turn stimulates the body's fat cells to form more fat. The increase in body fat is accompanied by an increase in the level of triglycerides, which is one of the components of fat.

plasma is a component of edema
Answer:
Edema occurs when an excessive volume of fluid accumulates in the tissues, either within cells (cellular edema) or within the collagen-mucopolysaccharide matrix distributed in the interstitial spaces (interstitial edema)
Explanation:
The definition of edema is a swelling due to the expansion of interstitial fluid volume in tissues or an organ. Several clinical conditions present with edema, making it a critical clinical feature for diagnostic medicine. Edema can present in numerous forms including unilateral, bilateral, localized, or generalized edema. Therefore, it is vital to assess the unique presentation and mechanism of edema to understand how it relates to disease pathophysiology, clinical presentation, and treatment. This review will present an overview of the general and cellular characteristics of edema, the mechanism, and pathophysiology of edema, and how edema relates to a specific disease presentation and development.
TASK TIME A. Greet/register the patient 3 minutes/patient B. Optometrist conducts eye exam 20 minutes/patient C. Frame/lenses selection 24 minutes/patient D. Glasses made (process can run 6 pairs of glasses at the same time) 66 minutes/patient E. Final fitting 5 minutes/patient

===========================================
Solution - Answer (a): The current maximum output would depend on slowest operations and that is B. Optometrist conducting eye exam (25min per patient) Hence total time available for task(B)= 10 hours * 60 min - (2 minute for first patient to greet + frame selection 20 min + glasses made 60 min + final fitting 5 min) = 600 -87 = 513 minutes. Hence, maximum capacity = 513/25 = 20.52 ~ 20 patients Answer (b): Since, the slowest process is B. Optometrist conducting eye test, if a person were to be added it must be there. The added capacity at no other place would increase total capacity of the patients processed in a day.

Discuss the physiology of the respiratory system, and explain the process of ventilation. (Be Specific)\
Physiology of the respiratory system is a follows:-
As a person inhales, the diaphragm contracts and moves downward. The space left in the chest allows the lungs to expand. Muscles in the ribs also help enlarge the chest cavity, pulling the rib cage upward and outward.Once the lungs expand, air moves in through the nose and mouth.The air travels down the trachea and into the lungs, allowing a person to breathe.The exchange of oxygen and carbon dioxide occurs before exhalation. When a person exhales, the diaphragm relaxes, the lungs recoil, and the air moves out of the lungs.Ventilation is commonly referred to as breathing.
It is the process of air flowing into the lungs during inspiration and out of the lungs during expiration.The air moves through the passages because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles.Individual alveoli have variable degrees of ventilation and perfusion in different regions of the lungs.To know more about respiration here
