Some man-made fibres, too, are derived from naturally occurring polymers. For instance, rayon and acetate, two of the first man-made fibres ever to be produced, are made of the same cellulose polymers that make up cotton, hemp, flax, and the structural fibres of wood.
<span>Stability is often preceded by a "crash" since the growing population eventually is too large for the available resources.
Stability refers to population stability. The growth of the population may destabilize the population stability.
The population size may become so large, so there will be no enough resources for species to survive. </span>
The answer is A because it is not formed from decaying marine animals.
It is to help transport macromolecules back and forth between the nucleus and the cytoplasm. the nuclear pore complex also serves as a barrier between the cytoplasm and nucleus to prevent harm to genetic material housed in the nucleus :)
