1. Deficiency of the macronutrientbones and teeth deformities.​

Answer»

Abstract

Malnutrition affects the oral health and a poor oral health in turn, may lead to malnutrition. This interdependent relationship SEES good nutritional health, thus promoting good oral health and vice versa. Malnutrition may alter the homeostasis, which can lead to disease progression of the oral cavity, REDUCE the resistance to the microbial biofilm and reduce the capacity of tissue healing. It may even affect the development of the oral cavity. Protein-energy malnutrition occurs when there is a deficiency of protein, energy foods or both, which are relative to a body’s need. Studies have suggested that ENAMEL hypoplasia, SALIVARY gland hypofunction and saliva compositional changes may be the mechanisms through which the malnutrition is associated with caries, while an altered eruption TIMING may create a challenge in the analysis of the age specific caries rates. This paper gives an insight on the relationship of the malnutrition and the protein-energy malnutrition with the oral health status.

LPG is filled in cylinders under pressure so that it is in the form of liquid. When the valve is opened it changes to gas . Then it is burned and it makes a good fuel. The correct set which can be associated with these changes respectively are

Answer»

Answer:

Normally, the gas is stored in liquid form under pressure in a steel container, cylinder or tank. The pressure inside the container will depend on the type of LPG (commercial butane or commercial PROPANE) and the outside temperature. When you START using LPG, some of the pressure in the container is released.

The pressure at which LPG becomes liquid, called its vapour pressure, likewise VARIES depending on composition and temperature; for example, it is approximately 220 kilopascals (32 PSI) for pure butane at 20 °C (68 °F), and approximately 2,200 kilopascals (320 psi) for pure propane at 55 °C (131 °F).

Answer»

Answer:

Explanation:

Mud is soil, loam, silt or clay mixed with water. It usually forms after rainfall or near water sources.

Mudbrick

Main article: Mudbrick

Mud HOUSE in 'Amran, Yemen

Mud can be made into mud bricks, also called adobe, by mixing mud with water, placing the mixture into MOULDS and then allowing it to DRY in open air.[1] Straw is sometimes used as a binder within the bricks, as it makes them a composite. When the brick would otherwise break, the straw will redistribute the FORCE throughout the brick, decreasing the chance of breakage.[2] Such buildings must be protected from groundwater, usually by building upon a masonry, fired brick, rock or rubble foundation, and also from wind-driven rain in damp climates, usually by deep roof overhangs. In extremely dry climates a well-drained flat roof may be protected with a well-prepared (puddled) and properly maintained dried mud coating, viable as the mud will EXPAND when moistened and so become more water resistant.[3] Adobe mudbricks were commonly used by the Pueblo Indians to build their homes and other necessary structures. In some countries there are entire cities made of mud brick houses.

What do think of when you heard or write about pollution​

Answer»

When I heard American pulmonologist Dr Nicholas Marks in an NPR PODCAST describe the LUNGS as “these exquisite machines, containers of air that just kind of blow life-giving oxygen into the blood through a thin wall, a membrane”, I understood immediately what he meant by the “POETRY of the lungs”. ALMOST exactly TWO years ago, I had watched helplessly as my mother – a trained Indian classical music vocalist – struggled to breathe in the terminal stages of the lung cancer that consumed her.

In those moments, breathing – an involuntary, effortless activity I’d always taken for granted – embodied this poetry. In my mother’s case, it became an elegy.
