Cari’s Story A. The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages. B. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes or abundant it triggers the cough reflex. C. There are macrophages found in the terminal bronchioles and alveoli that normally

Water Aerobics Water aerobics has been a strong growing type of exercise for many age groups for years. Water aerobics is a combination of arm and leg movements done in water for beginners. This type of aerobic exercise is typically done for less than an hour. This includes the same type of program as land aerobics with warm up and cool down periods. Swimming exercise uses more of the overall muscle mass of the body than almost any other form of exercise. (Water aerobics‚ "What is water aerobics"

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

Exercise 4 (Histology) 1.1 Give at least three distinguishing features of these groups of cells. Apical meristems have the following features: (1) a “border” of cells; (2) they follow order or shape; and (3) some cells are darker (indicating that they undergo mitosis). 2.1 Identify the tissue. The tissue is a vascular cambium. 4.5 (?) Is the epidermis uniseriate or multiseriate? In the cross section of a young root of Helianthus‚ the epidermis is uniseriate. 6.1 What do you call the outgrowths

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
