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.

The trait that is most likely to be selected in the population of plants growing in this region is trait encoding for short plant structure to reduce transport of water.
<h3>How are desert plants adapted?</h3>
Adaptation is any change that is made or undergone to suit a condition or environment.
Desert plants are adapted to the dry condition of the area by the possession of several traits.
According to this question, the area around the Sahara Desert is slowly changing into a dry region, similar to the desert.
This suggests that the trait that is most likely to be selected in the population of plants growing in this region is trait encoding for short plant structure to reduce transport of water.

Answer: My day was good kind of, it was a little stressful but good. Thank you for asking, how was your day?
Explanation:
The best solution to prevent them from becoming an invasive species is to develop plants that are unable to reproduce. Thus, the correct option is C.
<h3>What are Invasive species?</h3>
Invasive species may be defined as the group of organisms that are not indigenous, or native, to a particular area.
If such genetically modified plants have the characteristics of reproduction, then they produce offspring which are extremely different from the native population. This in the future leads to the process of speciation if can not be regulated in a limited manner.
Therefore, the correct option for this question is C.
