Answer: (TFIID) TBP-> TFIIB IIA--> TFIIF RNA POL II

Explanation:

Remember that in eukaryotic organisms, transcription and processing are coupled processes. There are 3 different types of Rna pol. In the case of RNA pol II transcribes genes that encode proteins (mRNA synthesis). Transcription factors are involved, for example: TFIID, TBPs, TAF (recognizes TATA promoter center, regulatory functions), TFIIA (stabilizes TBP union, antirepressant function), TFIIB (RNA Pol II starting point selection).

How do the characteristics of living things contribute to an organism's survival?
givi [52]
Any characteristic, whether a physical trait, a behaviour, a physiological adaptation etc can make an organism more or less likely to survive in a particular environment. 

A dark colour could help a rabbit survive if it lives in a dark forest, because predators can't see it so well, but it would be less likely to survive in the arctic, where the environment is all white and it would show up. 

In terms of the characteristics, think about: does it help the organism get food? Does it help protect the organism from predators? If it does, that organism is more likely to survive, and pass the characteristic on to it's offspring. If a bacterium has a characteristic of not being killed by antibiotics, this will help it to survive and breed.

The way a medication affects your body is an illustration of an external stimulus. Your vital signs altering as a result of a change in your body is an example of an internal stimulus.

<h3>Which 3 stimuli are they?</h3>

mechanical, thermal, and chemical stimuli can activate three different types of nerve endings. Some endings are more sensitive to one type of stimulus than the others, but all can detect all three.

<h3>What do humans respond to as stimuli?</h3>
