Endocrine gland(s) Group of answer choices secrete substances that do not alter the metabolism of their target cells, but have extracellular effects. secrete their products by way of ducts. have an unusually low density of blood capillaries. release their secretions directly into the blood. secretions may be released into the body surface.

The correct answer is: Release their secretions directly into the blood.

Explanation:

Glands are organs that regulate bodily functions by producing and releasing certain substances. Endocrine glands are a type of gland that specifically releases its product into the bloodstream.

Endocrine glands' products are called hormones and they travel through the blood vessels in order to reach their destination (the organ where they are supposed to act),

An example of an endocrine gland is the pancreas. The pancreas produces insulin and glucagon, two different hormones that act in different organs to regulate glucose levels.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
