Write a creative paragraph describing the “thought” process of the first cells that describes how this symbiosis occurred. (Of c

ourse, there was no real thought involved, but imagine that you are a cell that encounters an interesting prokaryotic cell and tries to convince it to be ingested and help you out in some way).

Once upon a time, there was a cell. It was moving around the primordial soup trying to make it in that harsh world. All of a sudden, it encountered a small prokaryotic cell. To be honest, the cell was feeling a little lonely and it was happy to come across somebody to share the habitat with. The two cells started spending a lot of time together, just quietly coexisting. The first cell started thinking how it would be so much easier to survive if the other, small cell were to live with me. I could provide safety and shelter, and the small cell can pay me back by providing me with the energy I need for my daily metabolic processes. The cell was hesitant for a second, but then bravely said ''Hey, what do you think about symbiosis?''. And the rest is (endosymbiotic)  history.

Cuál corresponde al tipo de crecimiento vegetativo en el que hojas subterráneas pueden dar origen a plantas idénticas
katen-ka-za [31]

Answer:

Propagación vegetativa

Explanation:

La propagación vegetativa es un tipo de reproducción asexual vegetal a partir de células, tejidos u órganos (por ejemplo, hojas, tallos y raíces) capaces de dar origen a organismos genéticamente idénticos mediante mitosis. Este mecanismo ha sido explotado en mejoramiento genético y en agronomía a fin de reproducir plantas con características fenotípicas deseadas a partir de un número reducido de células somáticas. Las regiones de la planta capaces de dar origen a un nuevo organismos se conocen como propágulos, los cuales pueden ser rizomas (a partir de raíces), tubérculos (tallos), estolones (brote laterales), etc. Diferentes tipos de suculentas tales como, por ejemplo, <em>Sedum morganianum</em>, Sedum<em> rubrotinctum</em>, <em>Kalanchoe daigremontiana</em> y <em>Graptosedum</em> o “California Sunset” se reproducen vegetativamente mediante propágulos foliares.

Consider this reaction:
Sonbull [250]
The answer is <span>There will be a shift toward the products.

To solve this problem, it is necessary to understand Le Chatelier's principle. According to the principle, if a chemical reaction undergoes changes in conditions, the chemical equilibrium will shift in order to undo the effects. In the reaction </span><span>PCl5(g) + heat </span>↔<span> PCl3 (g) + Cl2 (g), when pressure is decreased, the system will try to increase it. This will result in the increase of gaseous pressure, so the equilibrium will be shifted toward the products. </span>
