Answer:
D.They contain a regulatory domain that is functional when removed from the DNA-binding domain.
Explanation:
Transcriptional activators are transcriptional factors that positively regulate transcription of the gene (increase gene transcription). They usually contain two functional domains:
- DNA-binding domain which interacts with DNA
- Activation domain which interacts with other proteins.
Mechanism of action of activators includes their binding to the enhancers (DNA sequences) and recruitment of RNA polymerase II to the promoter.
A option i.e; glucose breaks down into ATP without any initial energy input. (It just spontaneously happens) does not make sense to make while all other are correct. So, the best option will be the A. because A option is not true about ATP.
Answer:

Explanation:
It seems that you haven't attached the given options for this question, but I hope this answer will help you find the correct answer. When we say protist, these are the organisms that are classified in the kingdom Protista. A pseudopod is <span>an extension of the plasma membrane by which certain cells locomote and engulf prey. An example for this organism would be amoebas. Hope this helps.</span>
