B. diatoms
C. green algae
D. euglenoids
E. amoeba
The answer is B. When diatoms die and fall off the ocean column to the ocean floor, they become part of sediments over time. When they are mined and exposed, they turn to a diatomite. Diatomaceous earth is significant as a pest repellant because of its hygroscopic property and has very abrasive particle hence it absorbs the water-protective fats and oils from the outermost layer of insects.

Answer:
In order to form delta weathering, erosion and deposition work together. The weathering breaks down the rocks by wind, water or frost. Erosion help to transport the broken particles and the deposition occurs in order to finally settle the eroded materials to a new location that results in the formation of a delta.
A delta is a fan-shaped area of land that is formed a deposition of sediments at the mouth of the river, where it empties into an ocean.

Answer:
the amount of pollutants in the air is unhealthy
Explanation:
AQI or Air Quality Index assesses the air quality. It indicates how clean or unhealthy the air is and its effects. It is calculated by measuring the concentration of major air pollutants across many locations in the country. The air quality is divided into six categories:
An AQI of 201 means that the air quality is very unhealthy. Everyone is susceptible to health hazards in this air quality.
