Most organisms can tolerate a very narrow pH range close to neutral, i.e., around pH 7. It is likely that there would not be much life in the lake at pH 3. Once the pH increases to above 5.5 to 6, it is more likely that life would begin to survive. Once the pH rises to above around 9, the solution is starting to become basic, and once again, few organisms will survive.
That is true (of that is what you are askungen for)
<h2>✅Amongst the array of proteins at the replication fork, DNA polymerases are central to the process of replication. These important enzymes can only add new nucleoside triphosphates onto an existing piece of DNA or RNA; they cannot synthesize DNA de novo (from scratch), for a given template.</h2>
Answer:
B) ecological succession
Explanation:
The analogy given in this question describes ECOLOGICAL SUCCESSION, which is the series of changes that an ecosystem undergoes over a period of time. Ecological succession is of two types viz: Primary succession and Secondary succession.
Primary succession involves the series of changes that occurs on a new habitat that has never been previously colonized. This is the case of the colonization of bare rocks with no plant life by LICHENS. The action of the lichen, which involves secretion of acids that disintegrates the rocks into soil, paves way for the colonization of that area by new species.
Lichens, via the role they play in primary succession by helping alter a barren area into a fertile one that accommodates other organisms, makes them be regarded as PIONEERS of primary succession.
