We must infer that a plant or animal of any species, is made up of special units, in all of which there dwells the intrinsic aptitude to aggregate into the form of that species: just as in the atoms of a salt, there dwells the intrinsic aptitude to crystallize in a particular way.
We are over 60 percent water by weight. We're just a big ball of... blob of water, with enough organic thickener added so we don't dribble away on the floor.
An impersonal and scientific knowledge of the structure of our bodies is the surest safeguard against prurient curiosity and lascivious gloating.
It is clear to all that the animal organism is a highly complex system consisting of an almost infinite series of parts connected both with one another and, as a total complex, with the surrounding world, with which it is in a state of equilibrium.
The explanation of types of structure in classes - as resulting from the will of the Deity, to create animals on certain plans - is no explanation. It has not the character of a physical law and is therefore utterly useless. It foretells nothing because we know nothing of the will of the Deity, how it acts and whether constant or inconstant like that of man.
In Darwin's time all of biology was a black box: not only the cell, or the eye, or digestion, or immunity, but every biological structure and function because, ultimately, no one could explain how biological processes occurred.
A virus is not just DNA; a virus is also packaged up, covered over with a series of proteins in a nice, elegant, well-compacted form.
We've managed to motion-track the silkworm's movement as it is building its cocoon. Our aim was to translate the motion-capture data into a 3D printer connected to a robotic arm in order to study the biological structure in larger scales.
The body enjoys a great share in our being, and has an eminent place in it. Its structure and composition, therefore, are worthy of proper consideration.
The structure of many cellular macromolecules has been revealed at the atomic level using x-ray crystallography.
It was Max Perutz who inspired me to go into structural biology when he gave a lecture at Harvard in 1963. As soon as I heard him talk, I decided that this is what I want to do.
The morphological characteristics of plant and animal species form the chief subject of the descriptive natural sciences and are the criteria for their classification. But not until recently has it been recognized that in living organisms, as in the realm of crystals, chemical differences parallel the variation in structure.
There's so many mysteries related to how flies are able to make their way through the world. I'd certainly like to know a lot more about how their brain works. I'd certainly like to know a lot more about just how they're put together. I mean, these animals are basically, topologically, spheres. They don't have bones as we do, of course.
To have hands, to have fingers, is weird. Real life is weird, to have fingers?
In the composition of the human frame there is a good deal of inflammable matter, however dormant it may lie for a time.
