Dispositional traits are personality traits that remain stable and relatively unchanging from about age. They refer to the tendency of an individual to behave in stable and predicted ways. It is similar with the concept of moods. Costa and McCrae believed that personality traits remain the same by the age of 30.
No, because two creatures with similar niches can evolve similar traits and appearances despite not having a common ancestor.
Answer:
1) intake of glucose molecules from the blood by specific transporters
2) high amount of glucose in the blood, sending signals toward the pancreas
3) binding of hormones with receptors on the liver
4) release of hormones from the receptors
5) synthesis of hormones by beta cells
Explanation:
During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells. The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
