Biologically

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:

Anatomy
Botany
Biochemia
Biogeography
Biofisia
Cytology or cell science
Ecology or environmental science

Semipermeabilized Cells
to Study Procollagen Assembly
Richard R. Wilson and Neil J. Bulleid
1. Introduction
This chapter will describe the preparation and use of a semipermeabilized
(SP) cell system that reconstitutes the initial stages in the assembly and modification of proteins entering the secretory pathway (1). The procedure involves
treating cells grown in culture with the detergent digitonin and isolating the
cells free from their cytosolic component (2). The expression of proteins in an
SP cell system allows protein assembly to be studied in an environment that
more closely resembles that of the intact cell. As this is an in vitro system, the
individual components can be manipulated easily, providing a means by which
cellular processes can be studied under a variety of conditions. In addition,
membrane-permeable chemical crosslinking reagents can be added in order to
facilitate the study of interaction between proteins within the endoplasmic
reticulum (ER) lumen (1,3). Furthermore, as the ER remains morphologically
intact, the spatial localization of folding and transport processes within the
reticular network may also be examined
