Answer:
The three main domains into which the organisms are classified are archaea, bacteria and eukarya.
Archaea : The archaea is more closely related to eukaryotes. Although they have bacteria like metabolism and have 70'S chromosomes but shows presence of introns and shows similar molecular mechanism like replication, transcription and translation similar to eukaryotes. These are found in the extreme conditions as well.
Bacteria: The bacteria have circular DNA with 70'S ribosomes. The cell membrane has ester linkage and no nucleosome formation occur in bacteria. The transcription and translation are coupled together with no further modification.
Eukarya: The eukaryotes have linear DNA with 80'S ribosomes. The cell membrane has ether linkage and proper nucleosome fprmation occurs in eukarya. The transcription and translation occurs separately in the distinct compartments and further modification occurs.
Answer:
A large number of organisms are supported by the soil. Living Organisms present in the soil are archaea, bacteria, actinomycetes, fungi, and algae. Ants, earthworms and nematodes, are other organisms that are found in soil. They all are important for the environment as they bring transformations in the soil which are important for life. They also impact the chemical and physical properties of the soil, these properties are studied by the soil biologists.
Answer:
Explanation:
Evolution is not a random process. The genetic variation on which natural selection acts may occur randomly, but natural selection itself is not random at all. The survival and reproductive success of an individual is directly related to the ways its inherited traits function in the context of its local environment. Whether or not an individual survives and reproduces depends on whether it has genes that produce traits that are well adapted to its environment.
