REALICE LA LECTURA DE LAS SIGUIENTES DEFINICIONES CONCEPTUALES E INDIQUE ENCERRANDO EN UN CIRCULO LA EXPRESIÓN QUE CORRESPONDA CON EL CONTEXTO DADO.
CHEMICAL ELEMENTS. A collection of atoms of one
type which cannot be decomposed into any simpler units by any chemical
transformation, but which may spontaneously change into other units by
radioactive processes. A chemical element is a substance that is made up of one
kind of atom.
a) can be transformed by
decomposition
b) can be changed by radiactive
processes
c) may contain more than one atom
dependeing of its kind
ENVIRONMENT. The assamblage of material factors
and conditions surrounding the living organism and its component parts. Environment
includes both external and internal factor. In the external environment,
inanimate objects and the forces associated
with them, constitute the physical environment, and the living things
and their derivates with which the
animal may be associated constitude the organic environment. Within its body,
it maintains an organization which constitutes an internal environment to which
all of its parts respond directly, whether or not they also have external
contacts.
a) The internal factors are part of
the environment of the living organism
b) Other people are part of the
physical environment associated with the living organism.
c) for an internal part to
constitute the invironment, it must be interrelated with the external parts.

SIGUIENTE PARRAFO:
QUANTUM MECHANICS. The theory of the motion of
a dynamical system is valid provided that there exists an observer for whom the
momenta of the particles of the system are small compared with c times
their mass. The quantum theory of the motion of a particle does not depart
significantly from the classical theory, however, unless the fractional
change in the momentum p over a distance of the order of the
de Broglie wavelength l = h/p is greater than, or of
the order of, unity.
