Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.
Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:
Cytology or cell science
Ecology or environmental science
نبذه عن الكتاب:
There is a long history of interest in volatile organic compounds (VOCs) in
indoor environments. This is evidenced by the large number of national and
regional studies/campaigns that have been undertaken to model, identify or
quantify indoor VOCs or that relate indoor levels of VOCs to indoor materials,
indoor activities and some perceived health/sensory effects. The main interest
in such studies lies in the fact that most people spend up to 80% of the day in
one indoor environment or another, where pollution levels can be higher,
pollutant sources are more varied and exposures are more important than
those found in outdoor microenvironments. Many novel insights have emerged
from the studies, and some of the main features of these insights are outlined
in this chapter. In particular, the types of VOCs commonly found in indoor air,
sources/source characteristics of indoor VOCs, measurement techniques for
profiling indoor VOCs, typical results from indoor air VOC studies, health
effects of VOCs, concepts for reducing indoor VOCs and new trends in indoor
VOC studies, particularly in the last decade, are discussed in the following
