Answer:
a. True
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.
Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.
During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.
For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.
1,000x2=2,000
2,000x2=4,000
4,000x2=8,000
8,000x2=16,000
Answer: 16,000
Answer:
Improvement of preservation techniques.
Explanation:
The most significant result of the technology revolution in archaeology is the improvement of preservation techniques used for archaeological sites. Modern technology also allows researchers to go to a site in order to find out the answers of additional questions. Modern archaeologists are fighting climate change, discovering how cultures evolved with the passage of time, and using technology to better understand human evolution.
