Your heart has four valves. Normally, these valves open to let blood flow through your heart, and then shut to keep it from flowing backward. Sometimes the valves don't work properly, causing some or all of the following disorders. In regurgitation, blood leaks back through the valve in the wrong direction. In valve prolapse, the valves have "floppy" flaps and don't close tightly. It's one of the most common heart valve conditions. Sometimes it causes regurgitation. In stenosis, the valve doesn't open enough and blocks blood flow. Based on your knowledge of the heart, explain how regurgitation, valve prolapse, and stenosis each adversely affects blood flow and the oxygenation of body tissues.
As the text just states vavles oone to let blood fkow through into the heart but it also said that sometime they're don't work properly and cause disorders and the valve prolapse is when the vavles have floppy flaps ans don't close

Explanation:
<span>Biotechnology is a set of techniques by which human beings modify living things or use them as tools. In its modern form, biotechnology uses the techniques of molecular biology to understand and manipulate the basic building blocks of living things. The earliest biotechnology, however, was the selective breeding of plants and animals to improve their food value. This was followed in time by the use of yeast to make bread, wine, and beer. These early forms of biotechnology began about ten thousand years ago and lie at the basis of human cultural evolution from small bands of hunter-gatherers to large, settled communities, cities, and nations, giving rise, in turn, to writing and other technologies. It is doubtful that, at the outset, the first biotechnological understood the effects of their actions, and so the reason for their persistence in pursuing, for example, selective breeding over the hundreds of generations necessary to show much advantage in food value, remains something of a mystery.</span>
The size of Rigel is 74 times that of the Sun.
<h3>
How many times Rigel radiation is stronger than sun rays?</h3>
Due to the Sun's production of radiations other than visible light, Rigel's radiation is 66,000 times more potent than the Sun's radiation.
With a surface temperature of roughly 20,000 degrees, Rigel is 3 1/2 times hotter than Betelgeuse and twice as hot as the sun.
At a distance of 860 light-years, Rigel is categorized by astronomers as a blue supergiant. A gigantic blue supergiant known as Rigel is estimated to be between 61,500 and 363,000 times as luminous (bright) as the sun. The radius of Rigel is more than 70 times that of the sun.
