And if any covariance, nevertheless, is observed, it should then find its origin out of pure geometry, in some kind of biological constraint
. In turn, such a biological constraint
might have either (i) a developmental origin, thus applying directly to [alpha], [rho], [delta], or (ii), an adaptive origin, directly applying to any of E, K, and D and, consequently affecting only indirectly, [alpha], [rho], and [delta] (through the relationships (1)).
(58) As with disability or gender, this supposed "accommodation" can appear unjustified because the "different" functioning of sexual orientation appears to involve contested individual, cultural, and moral choices rather than simply biological constraint
(We will consider the biological constraint
of fertility and its implications in the last part of this section.) Then, the first-order condition of Equation 6 is
According to Jaenisch (in a personal communication with the author following the hearing), faulty reprogramming does not create the same difficulties in differentiated cells derived from stem cells because in stem cell research (1) only cell lines, not whole organisms, are created, so that there is less of a biological constraint
to activate their developmental program, and (2) appropriate stem cells can be selected for use from those in culture, in contrast to reproductive cloning, where little nor no selection is possible.
This pattern stems from a universal biological constraint
, the researchers argue.
Is this predominantly a social or a biological constraint
? Have workers been completely helpless in defending their concept of a normal working day and enforcing effort norms below their psycho-physiological limit?
Weeds are serious biological constraint
to rice production and greatest competition due to them occurs in dry direct seeded method of rice stand establishment.
"Such policy decisions may not just come against political and biological constraints
, but also against social, cultural or religious constraints.
Here Herold quotes from a story I did for reason in 2004: "Nothing could be more natural to human beings than striving to liberate ourselves from our biological constraints
," I wrote.
The human auditory system has biological constraints
analogous to those of the human articulatory system.
Geneticist David Suzuki said the problem is that usually geneticists follow the inheritance ofgenes what biotechnology allows us to do is to take this organism and move it horizontally into a totally unrelated species without regard to the biological constraints
it's very bad science.
