Answer;
B. Both primary and secondary succession involve ecosystems recovering from a disruptive event.
Explanation;
-Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
-Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. Secondary succession follows a major disturbance, such as a fire or a flood.
Prokaryotic cells lack a true nucleus and cell organelles; example are bacterial cells.
Eukaryotic cells possess a true nucleus and cell organelles; examples are yeast cells and plant cells.
<h3>What are cells?</h3>
Cells are the basic unit of life.
All living organisms are composed of cells.
Some living organisms are composed of just one cell and are known as unicellular organisms.
Other living organisms are composed of more than one cell and are known as multicellular organisms.
There are two types of cells;
- prokaryotic cells, and
- eukaryotic cells
Prokaryotic cells are cells that lack a true nucleus and cell organelles. Example of prokaryotic cells are bacterial cells.
Eukaryotic cells are cells that possess a true nucleus and cell organelles. Examples of eukaryotic cells are yeast cells and plant cells.
In conclusion, cells could either be prokaryotic or eukaryotic cells.

The loss of the hydrogen on one molecule produces a negative charge, which is attracted to the positive charge formed by the loss of the hydroxy group from the other molecule.
Answer: Free-floating DNA is a term used to describe Prokaryotic DNA because such cells do not contain a distinct nucleus complete with a nuclear membrane. Such DNA simply exist in a region in the cytoplasm called nucleoid. Nucleoid is not distinct but can be found in any part of the cytoplasm, thus the term 'free-floating'.
