what is coroid and rancidity​

Answer 1

Answer:

Explanation:

Choroid: In the eye, a thin vascular layer between the sclera and the retina. The choroid supplies blood to the retina and conducts arteries and nerves to other structures in the eye.

Rancidity is a very general term and in its most general meaning, it refers to the spoilage of a food in such a way that it becomes undesirable (and usually unsafe) for consumption. When people say that a food has "gone bad," what they're usually talking about is rancidity. Most of the time, but not always, rancidity can change the odors or flavors of a food in such a way that it becomes very unpleasant to smell or taste.
