Answer:
Option A
Explanation:
Only an autotrophic species can convert methane into food.
Deep below the sea, methane and hydrogen sulfide are found in abundance. These gases get mixed into the sea water.
Autotrophic bacteria containing phosynthetic pigments oxidize these dissolved gases thereby producing food.
Hence these autotrophic bacteria’s will be considered as producers as they produce food.
Thus, option A is correct.
The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.
<h3>What are Nearctic and Palearctic?</h3>
The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.
Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.
Biogeographic regions are specific areas consisting of particular biological (biotic components) features.

The correct answer is: The synaptonemal complex.
Non-sister chromatids are chromatids from two homologous chromosomes. In prophase I of meiosis two homologous chromosomes pair and this pairing is called synapsis. This allows possible crossing over to occur. Two non-sister chromatids are connected in synapsis by a protein-RNA complex called the synaptonemal complex.
Crossing-over or the physical exchange of chromosome parts might occur and bring to genetic recombination. The sites of crossing-over between nonsister chromatids and are called chiasmata.
