If the blockage is removed from the blood vessel, what will happen to blood flow after removal?
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.
propose a definition for digestion using the following terms; nutrients, food, liquids, solids, transformation and digestive juices
Answer:
Large solid food particles are breakdown into small simper food molecules.
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.
Which of the following factors is used to define the climatic zones as tropical, temperate and polar
Answer:
temperature
Explanation:
and this climate zone the warmest months average less than 10° Celsius the North and South Poles have climates that are polar because of the nearby cold air masses for climate region near the equator with warm air mass is is known as tropical so there's more has to do with temperature

Physical description of a cell membrane?
Answer:
Cell membrane
Explanation:
A cell membrane is basically a protection of the cells. It controll what goes in and out of the cell and separates the interior of the cell from the outside environment. they contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, etc that mediate cellular activities to pass between organelles.
Hi. Is this correct?????
Answer:
Yes, that is correct.
Explanation:
Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: Cells and transport proteins are physically prevented from passing through the filtration membrane. This has the following effect on filtration: increased osmotic pressure in the filtrate that draws plasma through the membrane decreased osmotic pressure in the filtrate that increases the amount of filtration increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration neutral change in osmotic pressure with no effect on filtration
Answer:
The correct answer is ''increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration.''
Explanation:
Osmotic pressure is understood to be the force that must be applied to a solution when the flow of solvent needs to be stopped by means of a membrane with semi-permeable characteristics.Colloidal osmotic pressure in glomerular capillaries: it is the pressure exerted by proteins in the blood, which tends to recover the filtered water. To generate and maintain glomerular filtration, filtration pressure is required. That is, glomerular filtration is a physical phenomenon regulated by hemodynamic changes that affect the glomerulus and, although it is the initial excretion mechanism, it is not the exclusive regulator. Water, ions and some nutrients are mainly reabsorbed in the proximal tubule by different mechanisms. The water will follow a passive transport process by osmotic drag. The activity of the tubule is highly dependent on maintaining a fluid osmotic pressure similar to that of plasma. Since proteins and other elements that participate in the maintenance of the plasma osmotic pressure do not cross the glomerular barrier, in the tubule, the isoosmotic pressure with the plasma is fundamentally conditioned by the content of water and salt (dissociated as chlorine and Na +) of the ultrafiltered.
Cells and transport proteins are physically prevented from passing through the filtration membrane for this the correct answer is to increase osmotic pressure in the glomerular capillaries that reducing the amount of filtration.
Osmotic strain is known to be the pressure that needs to be carried out to an answer whilst the glide of solvent wishes to be stopped with the aid of a membrane with semi-permeable characteristics.Colloidal osmotic strain in glomerular capillaries: it's far the strain exerted with the aid of using proteins withinside the blood, which has a tendency to get better the filtered water. To generate and keep glomerular filtration, a filtration strain is required.What is glomerular filtration?That is, glomerular filtration is a bodily phenomenon regulated with the aid of using hemodynamic modifications that have an effect on the glomerulus and, even though it is the preliminary excretion mechanism, it isn't the different regulator.
Thus it is clear that the above answers are well explained.

Answer:
Explanation:
(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.
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.
