An inferential question can not be answered by looking at the text itself, but can be answered by inference or reference to some outside information. An example of an inferential question for the above text is, What season was it? (Autumn). 2. A literal question can be answered solely by referencing the text itself. An example of a literal question for the above text is, What colors were the leaves? (Red, orange and yellow). 3. An evaluative question seeks a judgment by the answerer, such as the value, worth, or truth of the text or its contents.
The somatostatin receptor family is a member of the G-protein-coupled receptor superfamily and consists of 5 subtypes each differentially distributed throughout the CNS and periphery. These receptors bind with high affinity to the endogenous polypeptides somatostatin-14, somatostatin-28 and cortistatin, as well as a vast array of synthetic ligands.
Hormones, though, only bind to certain, compatible receptor types. Thyroid hormones and each steroid hormone group-the estrogens, androgens, progestins, glucocorticoids (stress hormones), and mineralocorticoids (water and ion-regulating hormones) - have a matching hormone receptor type. In this case, the estrogen hormone 17-beta-estradiol is the ligand, and the estrogen receptor is the protein. 2  Binding turns on, or activates, a hormone receptor. 3  Activation sets in motion cell signaling systems that trigger gene expression and lead to responses typical of a particular hormone.
