Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.

Answer:
a. different species of birds can divide ecological spaces between them my matching the morphology to the food source.
Explanation:
Beak morphology allows the birds to select the suitable food type. The various species of Galapagos finches differ from each other in beak shape and size irrespective of their origin from common seed-eating stock.
The modification of beak shape and size into several directions allowed the finches to occupy the available empty ecological niches with respect to food types.
Diversification also reduced the competition between them and allowed the finches to colonize various ecological niches in accordance with their respective beak morphology.
Jack took a pill that increases his sympathetic nervous system arousal. According to Schachter and Singer's theory, putting him in an emotional situation and telling him that the pill will have no effect, would increase the chance of experiencing a strong emotion by him.
The two-factor theory of emotion was given by Stanley Schachter and Jerome E. Singer. According to Schachter and Singer's theory, an emotion is built on two factors i.e. physiological arousal as well as cognitive label.
The theory suggests that when an emotion is perceived, a physiological arousal takes place and the person makes use of the existing surroundings to look for emotional signals to tag the physiological arousal through cognition.
