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

lied to the stylus was approximately 50 pN,
preventing a force-induced conformational change of the E–F loop. This loop is
known to deform when the force is increased to 100 pN, thereby changing the
conformation of the bR surface.15 Interestingly, observations of different atomic
models from x-ray crystallography show
that the variation of this region is pronounced: the E–F loop is involved in the
contacts leading to the 3D crystals, and its
conformation is dictated by the 3D packing arrangement of the bR molecules. Although all the bR trimers are identical in
the 2D crystal displayed in Figure 3a, their
surface structure varies significantly.
These changes are related to the flexibility
of the bR surface rather than any noise introduced by the AFM. The flexibility of the
surface lowers the resolution of the ensemble, but structural details of each trimer
are still discernable. The variations in the
trimer structure can be used to calculate
the probability of finding a certain loop at
a certain position (x,y) by mapping the
corresponding peak positions of all individual bR trimers.16 The E–F loop, which
exhibits significant flexibility, is more delocalized than the A–B loop, which occupies a more defined position. The signal about
the threefold axis results from a lipid
molecule protruding 0.1 nm, which is only
occasionally visible in the raw data, but
if present, is precisely localized in the center
of the trimer. Therefore, a strong signal
emerges in the probability map (Figure 3c),
whereas no signal is present in the average
(Figure 3b). Precise localization of a surface
feature suggests that the corresponding
