Answer:
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
Explanation:
Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements ...
Although the cave fish have non functional eyes, it can see in the darkness of the cave and it catch their prey by contracting their mouth, thereby producing suctions that trap its preys. Thus, the cave fish expanded other sensory organs to make up for their sight less eyes. Also, cave fish, can only hear lower frequencies noises. The noise in the cave is always above this, thus the cave fish has developed the auditory adaptation of filtering out background noises in its environment.

Explanation:
The parasympathetic division of autonomous nervous system is also known as craniosacral division. The cell bodies of preganglionic neurons of parasympathetic division are located in the lateral gray matter of sacral segments (S2-S4) of spinal cord and in the nuclei of four cranial nerves in the brain stem. These cranial nerves as namely: oculomotor nerve (III), facial nerve (VII), glossopharyngeal nerve (IX), vagus nerve (X).
