The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.
How many genes control that trait
Laboratory tests and clinical procedures include:
- The blood glucose test and the glycosylated hemoglobin test are tests to identify diabetes and prediabetes (A1c).
- A glucose tolerance test may be administered to you if you're expecting to check for gestational diabetes.
- Your thyroid's functionality can be determined by a number of tests, chief among them a TSH measurement.
- Other examinations can evaluate parathyroid problems.
- Female hormonal problems can be identified with the aid of luteinizing hormone (LH) and follicle stimulating hormone (FSH) blood tests.
- Male hormonal problems can be discovered with tests for total testosterone.
- Other blood tests measure hormone levels that have an impact on numerous systems, including cortisol, 17-hydroxyprogesterone, DHEA-sulfate, ACTH, aldosterone, vitamin D, PTH, prolactin, and other estrogen analogues.
- Thyroglobulin (Tg) tests can be used to track thyroid malignancy.
<h3>What is Endocrinology?</h3>
•Endocrinology is the study of endocrine glands.
•Endocrine glands are a group of glands in the body which secrete hormones.
•The purpose of the secreted hormones is to evoke a specific response in other cells of the body which are located far away.

Sea stars (or starfish) feed off the oyster beds. If the oyster beds were destroyed it would deplete the major food source of the sea stars and they would begin to diminish.
