evidence of the endosymbiosis theory was found in the : nucleus and cytoplasms, mitochondria and endoplasmic reticulum, mitochon
alina1380 [7]

Answer:

Mitochondria and chloroplasts

Explanation:

These two organelles support the theory in that both have 70S ribosomes, the presence of a circular DNA within, and similar size. They can undergo division within the eukaryotic cyptoplasm. Both of these organelles are surrounded by a double membrane, which in the case of chloroplast is known to originate from ancient bacteria that lost its peptidoglycan component. Mitochondria and chloroplast both evolved from ancient free living bacteria that entered into larger cells, which in the case of mitochondria is known to be archaea and in the case of chloroplast is a eukaryotic cell. With this, these cells became dependent on it in a manner that it could not exist without it.

Why is a primary far less common and takes much longer to complete than secondary succession ?
chubhunter [2.5K]

Secondary succession generally takes place faster in comparison to primary succession as the substrate is already present. In the case of primary succession, there is no soil and it consumes much time to form.  

Primary succession takes place in mainly lifeless regions, that is, the regions in which the soil does not possess the tendency of sustaining life as an outcome of various factors.  

On the other hand, secondary succession takes place in the regions where a community that previously prevailed have been eradicated and is epitomized by smaller scale turbulence, which do not eradicate all the forms of life and nutrients from the environment.
