The correct response is,
the sequences within the promoter region at -10 and -35 are the most important for recognition by the sigma subunit.
Promoter region is the DNA sequence located upstream of the corresponding gene. Promoters for genes are essential as RNA polymerase recognizes the promoter region and binds to it forming the holoenzyme complex which can inititate transcription of the gene located downstream.
Sigma factor is the transcription factor found in bacteria, RNA polymerase has a subunit for the sigma factor, this factor only can recognise the sequences in the promoter region and bind to it thus initiating transcription.
Promoters usually have 2 parts of conserved regions, -10 element and -35 elements. Both these regions have conserved sequences.
The sigma factor is capable of identifying these conserved sequences at these particular locations of the promoter and can bind to these sequences.
once the sigma factor binds to these regions, RNA polymerase too binds and forms a transcription initiation complex and then transcription of the downstream gene is initiated.
Therefore promoters need not have identical sequences for the sigma factor to bind, as long as the -10 and -35 regions have conserved sequences the sigma factor can bind and transcription initiation will be followed.
corresponding in function but not in evolutionary origins. From a biology perspective.
Answer is Biogeochemical cycles.
In an ecosystem biotic (living) abiotic (non-living) components constantly interact each other. During these interactions, there is a transfer of nutrients between living organisms and the non-living environment. Thus, there is recycling of inorganic matter between living organisms and their non-living environment. This cycling of matter is called biogeochemical cycles.
These preferences may have been advantageous in our evolutionary history, when food was less reliably available

Correct answer: Socialization
Socialization is the process by which the person is taught about the customs, values, norms, and role of the society in, which they are living. It is guided by the teachers, parents, religious leaders and the community.
It is the whole process of learning throughout life and is responsible for influence in the beliefs, behavior and action of the individuals in the society.
The main purpose of the socialization is to involve the new members in a group.
