Answer:
An extreme disturbance that only affects the organisms above the ground.
Explanation:
A climax community refers to the final, stable stage in the ecological succession of an ecosystem. An example is a mature forest ecosystem with a stable species balance that can self-perpetuate as long as the environment remains unchanged.
A climax community is a term used in ecology to describe a stable stage in the ecological succession of an ecosystem. To put it simply, it is the final stage of succession, wherein the species of plants, animals, and fungi are balanced and capable of self-perpetuation without further change in species composition. This state is achieved over a long period through the natural evolution of the ecosystem and it persists as long as the environment remains unchanged.
For example, in a forest ecosystem, where succession might begin with pioneer species like lichens or moss, the climax community would be a stable forest populated by trees that are capable of reproducing there, like oak or beech trees. This forest would also contain a variety of animal species that have adapted to the conditions of the forest and are part of a balanced food chain.

Answer;
-Cell wall
Explanation;
-The cell wall is thick and fibrous and provides a barrier between the cell and its external environment.
-The plant cell wall is composed of cellulose. Cellulose is a structural carbohydrate and is considered a complex sugar because it is used in both protection and structure. The plant cell wall consists of three layers. Each layer has its own unique structure and function.
-A major role of the cell wall is to form a framework for the cell to prevent over expansion. Cellulose fibers, structural proteins, and other polysaccharides help to maintain the shape and form of the cell. Additional functions of the cell wall include: Support: The cell wall provides mechanical strength and support.
Cell wall supports and maintains the cell's shape and protects the cell from damage (option B)'
The plant cell is protected by a layer called the cell wall, which encloses the cell membrane. This rigid structure, composed of cellulose offers both support and safeguarding functions, for the cell. Additionally the cell wall plays a role, in preserving the cells shape and preventing it from rupturing when exposed to pressure.
The cell membrane on the hand forms an outer layer encompassing every type of cell.

Answer: any small molecule that can bind in a specific manner to a larger one
Explanation:
A ligand can be simply defined as an ion or a molecule that binds to usually a metallic element, in a coordination or complex compound.
The term "ligand" refers in cell biology to any small molecule that can bind in a specific manner to a larger one.
The functional significance of ligand-receptor binding in biological and molecule cell mechanisms is based on the fact that these binding activates signaling pathways required for the metabolism of a given cell.
Therefore, with this data, we can see that ligand receptor binding is fundamental during signaling cascades and it involves the activation of a specific metabolic pathway.
