is produced by the adrenal glands...
the gland will produce fewer amounts of the hormone...
produce chemicals called paracrine factors...
blood is called the thyroid.
Steroid hormones are synthesized from cholesterol, while nonsteroid hormones are synthesized from modified amino acids and small peptides. Non-steroid hormones are not lipid-soluble and therefore they need to bind to a receptor on a cell membrane; while steroid hormones can diffuse through the cell membrane.
Explanation:
Hormones are signaling molecules synthesized by glands. The endocrine glands include the adrenal glands, pineal gland, thyroid gland, parathyroid gland, pituitary gland, ovaries, testes, pancreas and hypothalamus. The pituitary gland is an endocrine gland that secretes hormones capable of stimulating the adrenal glands in order to produce steroid hormones. Hormone levels are often modulated by negative feedback, by which high-hormone levels reduce their own production. Paracrine factors (also known as growth and differentiation factors) are proteins that can diffuse across small distances in order to induce responses in neighboring cells. The thyroid gland secretes hormones involved in regulating metabolism and growth. Moreover, the thyroid gland also secretes calcitonin that regulates calcium levels in the blood.
Answer:
1. symbiont
Explanation:
Symbionts are organisms interacting in a biological relationship that can be of the type mutualistic, commensalistic, or parasitic
In this case, there is a relationship of commensalism between two organisms: the human and the bacterium.
Commensalism is a relationship between two symbionts where one benefits and the other is not harmed or helped. Commensalism it is derived from the word commensal (old french), used for human social interaction. Sometimes the word commensal is used in biology, however, the term symbiont is used more frequently to refer biological relationships.
