There is also general consensus about the broad components of biology: cell biology, heredity, evolution, diversity, ecology, animal structure and function, and plant structure and function (Starr, Evers, and Starr 2016). The question is: how can we structure the components so that they build ...
The International General Certificate of Secondary Education is a set of examinations and qualifications designed for 14 to 16-year-olds, although they can be taken at any age. Borne out of the GCSE used in England, Wales and Northern Ireland, the IGCSE has evolved to meet the needs of stud...

1982). In evolutionary biology, a relict species remains of a group that is mainly extinct (Grandcolas et al. 2014; Fig. 1). The basis for this inference is the observation that a species stands alone on a long phylogenetic branch, by comparison with a larger sister-group, because of ...
Population dynamics is a field of ecology that focuses on the size, composition, and distribution of populations and how these factors change over time. The composition of a population includes variables such as its age structure, sex ratio, and phenotyp...
I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line. And in the study of structural biology, China is likely to become the leader." She felt it was her fate to become a biologist. "I grew interested ...
The Soil Science Society of America is among the largest (http://www.soils.org). Many of these organizations are represented in the International Union of Soil Sciences (http://www.iuss.org). Soil scientists are trained to understand how the basic concepts of chemistry, biology, and physics...
Epigenetic memory is defined as the maintenance of gene expression states through cell generations in the absence of the initiating signals. PREs were first discovered in flies, in which they can mediate epigenetic memory of both silent and active states of their associated genes. Epigenetic memory ...
that are like the texts that one cell sends to the other and are read in order to elicit a response. They come from both healthy cells and diseased cells. What is interesting is that we are at a point where this field is still emerging, and we are still learn...
And no topic has grown and thrived quite like the philosophy of biology, which now has many students in the field producing high-quality articles and monographs. The success of this subject is due above all to the work and influence of one man: David Hull. In his own writings and in ...
