Achemical produced in one part of a multicellular organism that will have effects elsewhere within that creature is a(n):

enzyme

hormone

nutrient

antinutrient

The best answer is Hormone.

Hormones are chemicals secreted by one tissue and affect the functioning of other tissues and cells.

Hormones are secreted by glands of the endocrine system. They are secreted into the blood and also extracellular fluid. They then circulate in the blood and come into contact with essential all cells, but a specific hormone will only affect a limited number of cells, namely the cells that bear a receptor for that hormone.

Red blood cells for example have receptors for the insulin hormone that is produced by the pancreas. They will therefore be directly  affected by insulin while all other cells in the blood remain oblivious of this hormone..

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
