Answer:
C
Explanation:Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
Answer:
Centrosome
Explanation:
Diagram I and are II are single cells. Diagram I is an animal cell, Diagram II is a plant cell (can see the cell wall and the central vacuole).
G is the centrosome. The centrosome is made up of two cylindrical structures called centrioles. They are the microtubule organising centres (MTOCs) in cells. They regulate the assembly of microtubules during the cell cycle
Answer:
Porifera use their flagella to eating.
Explanation:
Porifera are immobile animals, typical of marine ecosystems, also called sea sponges and characterized by a lack of true tissue.
Coanocytes are one of the main cells of the porifers, and they are endowed with flagella that allow them to mobilize the water with food particles towards the microvilli, structures that trap them to be later absorbed.
The flagella play an important role in the feeding of the porifers, by conducting the food to the structures responsible for its absorption and processing.
The other options are not correct:
- <em>Porifera is immobile, so the flagella do not participate in swimming.</em>
- <em>Flagella do not participate in the reproductive process of marine sponges.</em>
<span>This example is used to illustrate the point that there are times when context and purpose are not enough to resolve all issues or questions. Context means that you are considering your audience, where purpose means that you are understanding and contemplating why you are doing or stating something. Here, the author is illustrating how these can be unimportant to a solution.</span>
