Answer:

1. A. be flattened

2. C. thermal effect

3. A. atherosclerosis

4. C. 100 J / cm2

Explanation:

Lasik and PRK both methods are used to treat hyperopia farsightedness. The PRK treatment is mostly common in Europe. The curvature of anterior corneal surface is flattened during the surgery.

Excimer laser angioplasty is a safe technique used for patients who are suffering with atherosclerosis.

The distance of the laser tip to tooth must be kept at least 10 cm to avoid thermal damage to the teeth.

Explain why during peak, exhausting levels of activity glycolysis generates the greater amount of ATP compared to the mitochondr
Mamont248 [21]

Answer:

The answer to this question lies in the number of steps, and substances, that are needed in order to yield ATP from ADP. While in anaerobic glycolysis pyruvic acid and lactic acid will yield their energy so that ADP can be re-synthetized into ATP, producing 2 molecules of ATP from that simple chain of reaction, aerobic glycolysis depends on the presence of oxygen, and several more chemical steps, chemical reactions, in order to finally yield all the ATPs it can yield.

Explanation:

When we are talking about intense training, like a sudden sprint, we are talking about the body needing ATP as fast as it possibly can get it so the muscles can move. Because of this immediacy, the body resorts first to its stores in muscle tissue and in the liver, to feed the anaerobic processes for ATP formation. The other process, called the Lactic Acid system, is the second of the anaerobic processes and its benefit is that while not requiring oxygen to produce ATP, it will use the stores of glycogen in the muscle and the liver, and through the chemical reactions of enzymes, it will produce enough ATP to power the exercise for at least a few minutes, without having to resort to the aerobic system. The number of steps taken to yield ATP are much lesser, and thus much more immediate, than in aerobic glycolysis.

qwelly [4]

The correct answer is less oxygen is absorbed by the body.

An infection of the lung parenchyma is what is meant by the term pneumonia. Health care workers must keep in mind that pneumonia is an umbrella word for a group of syndromes produced by a range of organisms, resulting in a diversity of presentations and consequences, rather than viewing it as a single disease. An infection of the lung parenchyma results from a number of diseases together referred to as pneumonia. There have been numerous attempts to categorize pneumonia according to its etiology, the clinical situation in which the patient contracted the infection, the pattern of lung parenchyma involvement, and other factors. This article examines pneumonia using the American Thoracic Society's system of classification.

B. Disengage from the stress

This is because our natural fight or flight kicks in and the only thing we can think about is getting away from the stress. A lot of people who are experiencing stress don’t think logically in the moment.
