Translocation A. The Munch pressure flow model The Principal of Pressure-Flow Model of Phloem Transport The Münch pressure-flow model is an explanation for the movement of organic materials in phloem .By the Münch pressure-flow experiment‚ two dialysis tubings are connected by a glass tube. The dialysis tubings only permeable to water or particles which have smaller size than the pores of the tubing‚but impermeable to the larger solutes.As larger molecules such as proteins and polysaccharides(starch)

Subject the patient to an SBT Number of studies have emphasized the importance of the discontinuation assessments for optimal outcomes post extubation‚ failure of which could result in undue delay in ventilation withdrawal‚ leading to increased rise in infection‚ longer exposure to potentially toxic airway pressure and volume‚ excessive sedation needs‚ longer stay and higher costs (3‚43‚84‚85). Then again‚ overly aggressive/premature ventilation withdrawal attempts have their own hazards of airway

After a great deal of practice‚ the brain itself begins to “rewire” by changing improving connections between relevant neurons and eliminating unused ones to make the command for the motion as fast as possible. In the brain there is the concept of action and reward. For example‚ if it does a trick and it receives a treat‚ it will usually do the same trick to get a treat. The brain will strengthen necessary couplings and remove unnecessary ones if the task is completed and does what it is supposed

Cari’s Story How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? An infection will spread because the pharynx‚ larynx and sinuses are all connected‚ so the infection is going to spread to the sinuses and the surrounding areas. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? The cough reflex is a deep and long inhalation that is followed by the closing the glottis‚ this causes a strong exhalation

Variagated Leaves Total absence of plastid pigments causes a sector of a leaf or stem to have white patches. This condition is termed variegation (Metrosideros). Variegation is produced when there is a cell mutation (cytological chimera)‚ and all cells produced from that mutant mother cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are

Outcome 6 Energy SystemsExplain when he would require the different systems and explain why. Middle distance runners can handle an unbelievable range of metabolic stress. The three energy systems that an athlete would use during a 1500 metre race are; 1: ATP-PC System (anaerobic); 2: Lactic Acid System (anaerobic glycolysis); 3: Aerobic System (oxidative system). The ATP-PC System (anaerobic) is used during short bursts of activity during the race. This could be at the start of the race and more

If indoor workouts are your thing during the winter‚ you may get bored with the same old workouts. Even the variety of machines and activities at the gym can get old when you do them over and over. To keep yourself interested‚ try mixing up your workouts and trying some new ideas: Mix and Match your Cardio. If you tend to do the same machines all the time‚ try a cardio medley. Choose 5 different machines and spend 5 or more minutes on each. Or choose 3 machines and hit each for 15 minutes. Mixing
