Lung compliance may be abnormally high or low due to atelectasis, pulmonary fibrosis, and emphysema.
Lung compliance, also known as pulmonary compliance, is a gauge of the lung's extensibility. It is divided into static compliance and dynamic compliance measurements in clinical practice. The volume change for any given applied pressure is referred to as static lung compliance. Pulmonary fibrosis, pneumonia, and pulmonary edema are frequent causes of decreased lung compliance. An increase in resistance is a symptom of an obstructive lung disease. The pressure volume relationship is identical to that in a healthy lung during normal breathing. Low compliance denotes a stiff lung and can be compared to a thick balloon, as is frequently the case in fibrosis. Emphysema patients frequently have high compliance, which indicates pliable lung tissue and can be compared to a grocery bag.

What are the 3 characteristics of Cubism?.
The Cubist movement rejected conventional perspective and foreshortening techniques in favor of a flat, the double plane for the picture plane.
What did Cubism's central concept entail?Without employing methods like framing or graduated shading to make their paintings appear realistic, the artists aimed to depict the entire structure of their subject matter. Instead of just showing how things appear, they sought to depict them as they actually are.
What, in plain terms, is cubism?Pablo Picasso & Georges Braque, two artists, created the cubism movement in about 1907–1908. It was a groundbreaking new method of depicting reality. They combined many perspectives of the same subject matter (typically objects or persons) to create artworks that look fractured and abstract.

If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production of high-energy sugars?.
If carbon dioxide is removed from a plant's environment, then no sugar will be produced by the plant.
Plants make high-end sugars through a process that is referred to as photosynthesis. Carbon dioxide and water are converted into glucose and oxygen in the presence of sunlight as a result of photosynthesis.
If carbon dioxide is removed from a plant's environment, then this means that one of the reactants for the process of photosynthesis would go missing. As a result, no photosynthesis will take place and no sugars will be produced by such a plant. For producing sugars, all components required for the process of photosynthesis are essential in a plant.

why does adding a small amount of water to a substance increase its cohesion but adding a lot of water decrease its cohesion
In contrast to too much water, which will increase surface tension and push the grains apart, a small amount of water causes the surface tension to decrease, allowing the grains to bond together.
What affects mass wasting?1. Slope failure typically occurs more frequently on steep slopes than on gentler slopes. For loose sediment, there is typically a slope angle that distinguishes between a tendency for slope failure and slope stability. The angle of repose is what is meant by this. This angle is about 34 degrees for loose sand. For other materials, this angle may change.
2. The instability of a slope is increased by the addition of water. Rock pieces are easier to slide down slopes because it lubricates them. This is why mass wasting is more frequent during rainy seasons. It turns out that increased surface tension in the soil caused by a small amount of water can help slope stability. Naturally, surface tension has no effect when there is too much water present.
3. Because its roots anchor sediments, vegetation improves slope stability. Additional water that could cause a slope breakdown can be absorbed by plants. But vegetation on a slope cannot stop an excessive amount of water in the soil.
4. As was already mentioned in previous lectures, earthquakes typically enhance the chance of mass wasting in landslide-prone areas.
5. Mass waste is most likely to get worse if there is a lot of loose material on the slope.
6. When a slope falls, landslides tend to accelerate because of high relief (the vertical distance between high and low altitudes).
