Answer:
In biology, biotic components can be described as the living components of an ecosystem. Abiotic components can be described as the non-living components of an ecosystem. Both, the biotic and abiotic factors are important in maintaining a stable ecosystem whether it be a terrestrial ecosystem or an aquatic ecosystem.
Some of the abiotic factors which affect the distribution of the aquatic life are:
- <em>Amount of light: </em>The area which will receive more light will result in greater biodiversity. This is because there will be more number of plants in this area of the water and more plants means that there will be more aquatic animals present to feed on these plants.
- <em>Water flow rate: </em>Some organisms in the water are sensitive to high flow rate. More diversity will be seen in areas where the water flow is stable.
- <em>Temperature: </em>Although many of the fishes are cold-blooded, yet there will be greater diversity where the temperature will be moderate.
Some of the biotic factors which affect the distribution of the aquatic life are:
- <em>Predators: </em>If there are more number of predators than the preys, then the prey diversity will have a serious threat.
- <em>Aquatic plants: </em>There will be more aquatic biodiversity in the areas where there will be more aquatic plants.

Taxonomy, or taxonomy, is originally derived from the need for scientific classification of species. It now extends to other sciences, including human sciences, information sciences and computer science. Sometimes we call it "taxonomy" to describe the result of a taxonomic activity, that is to say a classification.
The traditional classification is based on a fixed hierarchy of categories (taxon ranks), defined as follows:
Reign (or Kingdom) (there are currently six) → Division (or phylum) → class → order → family → gender → species.
Answer: d. none of the other answers
Explanation:
Enzymes that turn chemical energy into mechanical work are molecular motors.
There are three main components of cytoskeleton including microtubules, actin filaments and Intermediate filaments. Only actin filaments and microtubules carry the motor-driven transport on the cytoskeleton.
The most important feature of intermediate filaments is to provide the plasma membrane with mechanical support where it comes into contact with the extracellular matrix and other cells.
Unlike microtubules and microfilament , intermediate filaments are not involved in motility of the cells, hence do not associat with molecular motors.
Hence, the correct option is d.
The use of cars can cause chemical pollution by the release of carbon in the air.
