The condition hypothyroidism is characterized by a decrease in the synthesis and secretion of the chemical thyroid hormone from the thyroid gland, an organ in the neck that is part of the endocrine system. Which level of organization does not match this condition?
A. The thyroid glad is regulated by others hormones from other glands in the body at an organ system level.
B. The endocrine system works with the cardiovascular system to allow transporting the hormones throughout the body function at the organism level.
C. At the tissue level group's of follicular cells that make the thyroid hormones form a spherical structure with a hollow interior called follicle.
D. The plasma membrane of follicular cells that are found in the thyroid gland is made up of phospholipid bilayer at the tissue level.

- Why does epinephrine bind its receptor in a different location than cortisol binds its receptor? A. The receptor binding site of epinephrine must be extracellular because the cell’s membrane is a barrier that prevents epinephrine from reaching any intracellular binding sites. B. The membrane blocks cortisol from entering the cell, therefore cortisol must bind the receptor on the cell’s extracellular surface. C. Cortisol easily passes through the cell’s plasma membrane. Therefore, the cortisol receptor is found intracellularly. D. Epinephrine can dissolve across the plasma membrane and bind its intracellular receptor. E. Both A&C F. Both B&Darrow_forwardWhich of the following statements about hormones is not correct? A. The persistance of a hormone in the blood is usually of short duration.B.
