Atmosphere; cryosphere is irrelevant, the biosphere refers to the atmosphere, hydrosphere and geosphere,
-the geosphere is all solid rock
-the atmosphere is air, which is the only sphere the hydrosphere is in contact with and thus where the diffusion occurs
You didn't put any options but an example of biological weather can be the weakening of a substance such as a rock being broken down due to various plants(... so nothing man made). Hope this helps :)
1) DNA condenses into
chromosomes. = prophase
2)Homologous pairs align
to initiate crossover. = metaphase
3) Microtubules pull apart the
homologous pairs toward
opposite poles. = anaphase
4) Nuclear envelopes develop
around the nuclei. = telophase
5) Cytoplasm pinches inward
near the cell furrow = cytokinesis
Through light transferring in to a surface
