answered-by-expert Expert Answer
1. Hormones are chemical substances produced within an animal or a plant which act as "chemical messengers" as means of communication among various parts of an organism.
 
2. Diastolic pressure is the pressure in the bloodstream when the heart relaxes and dilates, filling with blood. A normal diastolic blood pressure number is 80 or less
