The S 3 molecule, known as trisulfur, sulfur trimer, thiozone, or triatomic sulfur, is a cherry-red allotrope of sulfur.It comprises about 10% of vaporised sulfur at 713 K (440 °C; 824 °F) and 1,333 Pa (10.00 mmHg; 0.1933 psi).
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...

In the secondary cell wall of fibres of trees a low microfibril angle is found in the S2-layer, while S1 and S3-layers show a higher MFA . However, the MFA can also change depending on the loads on the tissue. It has been shown that in reaction wood the MFA in S2-layer can vary. Tension wood has a low MFA, meaning that the microfibril is ...
In the science curriculum, ninth grade students are required, in most areas, to take biology. But they can take different courses before they take Biology such as Integrated Science. [citation needed]. Other forms of sciences such as basic physical science or earth sciences could also be part of the curriculum as well, depending on the school ...
