Answer:
catabolite activator protein (CAP)
Explanation:
Catabolite activator protein (CAP) is a homodimeric transcriptional activator required for transcription initiation of catabolite-sensitive genes in <em>Escherichia coli</em>. CAP contains a ligand-binding domain at its N-terminus and a DNA-binding domain at its C-terminus. CAP activates transcription by binding at target DNA sites on promoter sequences, thereby enhancing the ability of the RNA polymerase to bind and initiate transcription. CAP binds cyclic AMP (cAMP) to increase CAP’s affinity to DNA and thus activates the transcription of genes for catabolism, such as the lactose (lac) operon genes (the lac operon is a set of genes that encode for enzymes taking part in lactose metabolism).
Answer:
the ventral respiratory group
Explanation:
The respiratory centers are present in the brain stem. Five major respiratory group are Dorsal respiratory group, Ventral respiratory group, Pontine respiratory group, Pneumotaxic center and Apneustic center.
Ventral respiratory group controls the process of respiration. The neurons of ventral respiratory group become active during forceful breathing and may result in inspiration.
Thus, the correct answer is option (A).
Stairs are an example of an incline plane.
The answer is North Pacific Gyre, just took the test. :)
