Then, as reproduction proceeds over the next 3-5 days, vit mRNA levels are titrated downward in response to actual reproductive demand.
For example, the absence of aging in fissile organisms could be explained readily in terms of the absence of decreases in the forces of natural selection that arise when reproduction proceeds by symmetrical fission.
Third, we note that cell cycling in the MZ sets the pace at which reproduction proceeds in our simulations: faster germ-cell cycling leads to faster filling of the MeZ, faster pushing out of proximal MeZ cells once the MeZ is full, and thus faster oocyte maturation and reproduction.
Even if reproduction proceeds at the same rate after the initial division (as expected if newly budded cells grow at equal rates irrespective of the size of their genetically identical parents), zygotes that are initially closer to the optimal size should ultimately produce more offspring in proportion to the size of these "head-starts".
While no mammal has yet undergone birth within the space environment, studies spanning the gravity continuum from 0- to 2-g are revealing startling insights into how reproduction and development may proceed under gravitational conditions deviating from those typically experienced on Earth.
The mosquito harbours the parasites as they proceed through stages of reproduction and maturation.
The genetic algorithm can generate filial generation colony which have higher average fitness and better individuals through the reproduction and crossover operators and can make the evolutionary process proceed to the optimum solution.
Regardless of how the third and fourth steps proceed, the fifth step in the cycle of infection is replication (reproduction of the parental genome to make progeny genomes).
Her argument's plausibility increased with the discovery that leptin permits sexual maturation to proceed by conveying a signal that fat stores are adequate for reproduction [ 17- 19].
In April 2011, Woolworths amended its trademark application to remove various goods and services, such as "apparatus for recording, transmission or reproduction of sound or images" and Apple withdrew its opposition, allowing the trademark to proceed to registration.
