The answer here is Prophase 1 (A)
In the event of meiosis, Prophase 1 occurs right after Interphase (stage when DNA is replicated). In the Prophase 1 stage, chromosomes condense and pair off and then exchange DNA between each other in a manner of crossing-over homologous chromosomes. The cross-over procedure forms a X-like region called Chiasmata that holds the homologous chromosomes intact.

hope it helps :)
They essentially do what humans do. They eat the food, which in this case is decaying materials (detritus), break down the material chemically and mechanically, absorb the nutrients they need, then excrete the 'waste', which contains other nutrients. Soil is basically clay, sand, silt and decomposer's cr*p.<span />
Abiotic factors are those that are non-living aspects of the habitat of living organisms that affect them and the ecosystems' dynamics. Without abiotic factors, biology could not be - they may impact organisms in <span>their reproduction, </span>growth, and maintenance.
Examples of abiotic factors may include water, tides, light, pressure, radiation, humidity<span>, </span>soil constitution, and others such as the ones mentioned on the question - rainfall and temperature.
