Question

Which of the following is a characteristic of hormones?
A. Organic complex substances
B. Chemical messenger
C. Glandular secretion
D. Blood cells

Answer 1

Hint: Hormones are chemical messengers that are secreted directly into the bloodstream, where they are carried to the body's organs and tissues to perform their functions. Hormones affect many different elements of body functioning and activities.

Complete answer:
Animal hormones are often (but not always) synthesized in specialized hormone-synthesizing glands, unlike plant hormones. The hormones are subsequently released into the bloodstream and carried throughout the body.
Hormones are produced by the body's endocrine glands. Because the glands lack ducts, hormones are released directly into the bloodstream instead of viaducts. The following are some of the body's primary endocrine glands:
1. Pituitary gland
2. Pineal gland
3. Thymus
4. Thyroid
5. Adrenal glands
6. Pancreas
7. Testes
8. Ovaries
A hormone is secreted in tiny amounts by these organs, and it only takes a small quantity to cause profound changes in the body. Even the tiniest excess of hormone production, as well as the tiniest deficit in a hormone, can cause illness.
So, Hormones are chemical messengers that transport information in a fluid-like state. It gets to the target cell and produces the intended outcome. A hormone is a type of regulatory molecule generated by glands in all multicellular animals and delivered to a distant target organ through the circulatory system to control its physiology and behavior.

Thus, the answer is option B: Chemical messenger.

Note:
Hormone abnormalities are identified in the lab as well as through clinical signs and symptoms. Hormone irregularities can be detected via laboratory testing on body fluids such as blood, urine, or saliva. A synthetic hormone replacement treatment may be utilized in situations of hormone shortage, and medicines may be used to reduce the consequences of excess hormone production in cases of excess hormone production.
