Answer:
The correct answer would be b. the environment.
Due to movement of tectonic plates the organisms would experience different environment. For example, different habitat, different food source et cetera.
As an adaptation to the changing environment different organisms would evolve in different species.
For example, in Galapagos island fiches had developed different sizes and shapes of beaks as a result of adaptation towards different environment.
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.
Answer:
Answer: The correct option is C) It produces ATP.
Photosynthesis is the process by which green plants prepare their own food using CO₂ and H₂O in the presence of sunlight. It is primarily divided into light reaction and dark reaction.
The light reaction takes place in the thylakoid membranes of the chloroplast. In this reaction, energy from sunlight is captured by the chlorophyll pigment via a series of chemical reactions. This results in the formation of two high energy chemical compounds, which are ATP and NADPH.
These compounds are further used in the dark reaction for the synthesis of food ( which is glucose).
Thus, it produces ATP is true for the light reaction of photosynthesis.
