The correct answer is: b. It is free to bind to another promoter and begin transcription
Transcription is the first step of gene expression in which DNA molecule is copied (transcribed) into RNA (mRNA) by RNA polymerase. The process of transcription is divided into three phases:
1. Initiation
• RNA polymerase with transcriptional factors bind to gene promoter
• RNA polymerase unwinds DNA double helix (transcription bubble is formed)
2. Elongation
• RNA polymerases adds nucleotides complementary to DNA
3. Termination
• RNA polymerase gets to stop codon (transcribes a sequence of DNA known as a terminator)
• Formed complementary RNA strand is released from DNA-RNA complex.
RNA polymerase is also released and can transcribe some other gene by binding to its promotor. RNA polymerase will transcribe just the genes whose products are needed at a particular moment.
In a swamp a bird and a turtle feed on the same kind of fish. This will most likely result in Competition is an relations between organisms or species in which both need a resource that is in limited pool.
<h3>What is competition in an ecosystem?</h3>
Competition will happen between organisms in an ecosystem when their niches overlay , they both try to utilize the exact resource and the resource is in lack of supply.
Fuana contend for chow, water and area to live. flora contend for light, water, minerals and root area.
So,Competition is an relations between organisms or species in which both need a resource that is in limited pool.

Answer:
The correct answer will be option-C.
Explanation:
Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.
When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.
In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.
Thus, Option-C is the correct answer.
It is probably the type of environment they live in
