Ans.
Unicellular organisms are those organisms that are made up of a single cell, while multicellular organisms are made of up more than one cell. During 17th century, a scientist could distinguish between an unicellular and a multicellular organism by using simple microscope, developed by Antony Van Leeuwenhoek. In the mid-20th century and 21st Century, a scientist could make distinction between unicellular and multicellular organisms, by using advance microscopy techniques, such as electron microscopy and electron microscopy.
True.
In the process of the nitrogen cycle. <span>
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA. </span><span>
