If the blockage is removed from the blood vessel, what will happen to blood flow after removal?

Answers

Answer:

Normally, blood flows freely through your blood vessels, arteries, and veins. Your arteries carry blood with oxygen and nutrients to your body. Yours veins carry waste products back to the heart. In some cases, the blood thickens and clumps to form a blood clot in one of these vessels. This can block the blood flow. When blood flow is blocked, nearby tissues can be damaged.During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.

Answers

Answer:

The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.

Explanation:

Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria

If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.

When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

Explanation:

Digestion is the process in which large solid food particles are breakdown into small simper food molecules so that they can be absorbed by the body and added to the blood plasma. These simpler molecules are absorbed by the cells to generate energy in the form of ATP. This transformation from solid food particles into simpler molecule through mechanical and chemical digestion. Mechanical digestion starts from the mouth in which the sold big particles are changed into smaller pieces with the help of teeth while on the other hand, the chemical digestion occurs through digestive juices that helps in break down.

Answers

Answer:

Due to the presence of suitable environment.

Explanation:

Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.

Margaret Thatcher, Joe Lieberman, John McCain, Charles Krauthammer and other notables offered variations of The Economists cover headline: The Man Who Beat Communism.Actually, Jack F. Matlock Jr. writes in Reagan and Gorbachev, it was not so simple. . . . . In both the title of his memoir and the story it tells, he gives co-star billing to Mikhail Gorbachev.Reagan himself went even farther. Asked at a press conference in Moscow in 1988, his last year in office, about the role he played in the great drama of the late 20th century, he described himself essentially as a supporting actor. Mr. Gorbachev, he said, deserves most of the credit, as the leader of this country.Excerpt from Strobe Talbotts 2004 review of Reagan and Gorbachev: How the Cold War Ended by Jack F. Matlock Jr., the senior coordinator of policy toward the Soviet Union under President Reagana) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Reagans policies and US pressure.b) Identify ONE specific example of how historians might argue that the end of the Cold War was attributable to Gorbachevs leadership.c) Identify ONE reason (other than partisanship), based on the events of the last decade of the Cold War, that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War.A) One specific example of how historians might argue that the end of the Cold War was due to Reagans policies and US pressure is the fact that during his presidency, he increased relations with the Soviet Union, while simultaneously building up the American army as both a backup plan and to prepare for a potential arms race, which put pressure on the Soviet Union. Reagan also proposed treaties between the USSR, simultaneously putting pressure on the USSR, essentially forcing them to enter into some sort of treaty or else they will enter an arms race that they likely wouldnt win.B) One specific example of how historians might argue that the end of the Cold War was a result of Gorbachevs leadership was the fact that he instituted a lot of reforms that made the country more capitalist than before, and also more democratic, which pleased the rest of the world and increased foreign relations. He attempted to ease tensions within the country and its satellite states, and started to distance the country from authoritarian rule to move towards a system more suitable for the current world. These new reforms increased foreign relations, and led to the end of the Cold War. C) One reason that historians might still debate the respective influences of Reagan and Gorbachev on the end of the Cold War is that fact that while they both contributed to it, there were a lot of other factors at play during that time period. It is often stated by historians, particularly in this case some historians at The Belfer Center at the Harvard Kennedy School in Cambridge, Massachusetts, that even if Gorbachev had not instituted the reforms that he did, the communist ideology would likely have still dissolved in the USSR. So even if Gorbachev didnt become president and put those reforms in place to decrease the influence of the communist ideology of the people, it still would have likely happened anyway. On the other hand, one could argue that Reagan didnt have much of an influence on the end of the Cold War either, as he himself even states that without Gorbachev, the end of the Cold War wouldnt have been possible. He simply made decisions that were advantageous at the time that were essentially put in place for him. Those are both sides of the argument that many historians have about the influence of each leader on the end of the Cold War. plzzzz helpIn your journal, practice a PATTR + PASAFE of "Small Change: Why the Revolution Will Not Be Tweeted" by Malcolm Gladwell from The Language of Composition.
