Justify key features in the non-specialist lab ?

-compare it with a chemistry specialist lab ?

 A non-specialist laboratory is made to be useful to several purposes, without focusing in a specific area. The lab structure – ceiling, walls, floor and furniture – cannot react with the experiments carried out in it and it has to allow easy circulation of people and air. The furniture consists of fixed benches with clear surfaces which are chemical and heat proof and also some moving furniture which is used to adapt the lab to a more specific function. There is also a storage area and it is obligated the presence of safety equipment such as fire extinguishers, fire blanket, safety solutions and eye wash – some laboratories can also have a safety shower. The services that a non-specific laboratory has to offer are water, gas, electricity and in some cases, a vacuum line.

A chemistry specialist laboratory presents the basic infrastructure of a non-specialist lab, plus some specific areas and equipment. For example, in a chemistry lab there are areas used only to check and test chemicals and these areas contain specific equipment that attends the different types of testing.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
