The field of developmental biology has as its major concern embryogenesis: the generation of fully-formed organisms from a fertilized egg, the zygote. Other issues in this field, organ regeneration and tissue repair in organisms that have already passed through the embryonic stages, have in common...

Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos. This led them to believe that the cells in the early embryo are undetermined in the sense that each...
Issues around identity, agency and reflexivity are opened up and explored in a refreshing new perspective that deepens our understanding of organization and institutions. thorougly invigorates the study of process and brings the organization to three-dimensional life for a new generation of students an...
All living things are composed of cells. A. True B. False Correct Answer A. True Explanation All living things are composed of cells because cells are the basic structural and functional units of life. They are responsible for carrying out essential processes such as growth, reproduction, and ...
Discerning the relationship between sociality and longevity would permit a deeper understanding of how animal life history evolved. Here, we perform a phylogenetic comparative analysis of ~1000 mammalian species on three states of social organization (solitary, pair-living, and group-living) and longevi...
However, how microenvironments of biomolecular condensates affect their structure and function remains unknown. In this study, we investigated the micropolarity and microviscosity of model biomolecular condensates by fluorescence lifetime imaging coupling with environmentally sensitive fluorophores. Using both ...

Hence, quinol:oxygen oxidoreductase supercomplexes were detected in all branches of the tree of life supporting the idea that this highly organized state is a general feature of living organisms.
