Which factors contribute to the disintegration of the rock samples?
Answer:
The Trypanosoma most closely resembles green algae.
Explanation:
Trypanosoma exhibits structural similarities to green algae, which is unicellular. The primary similarity between Trypanosoma and green algae lies in their flagella, both utilizing them for movement from one location to another. Both are unicellular organisms where a single cell manages all life processes.
Answer:
Reena is composting as a method to recycle biodegradable waste, transforming it into a natural fertilizer.
Explanation:
By placing the organic material into the soil-filled pot, soil-dwelling microorganisms are able to break down the waste, producing fertile matter. This enriched soil is beneficial for plant health, providing essential nutrients needed for growth.
Composting involves a biological oxidation process that is regulated, with microorganisms and other decomposers like earthworms facilitating the breakdown of solid waste. The final product serves as a natural fertilizer and acts as an alternative to chemical options. It's crucial to manage temperature and humidity during this process, which may last between one to two weeks until all solid waste is decomposed and integrated with the soil.
Population density = total number of individuals divided by land area
land area should be expressed in square kilometers
thus, 120 ha = 120 x 0.01 = 1.2 square kilometers since 1 ha = 0.01 square kilometers
total population= (80 x 1500)/100 = 1200
so, the population density is 1200/1.2 = 1000
