9966 [12]

Answer:The uterus has receptors for oxytocin, but not for cholecystokinin.

Explanation:

Both of the hormones are released and travel via same pathway towards the uterus. The uterus responds to oxytocin but does not responds to cholecystokinin because the uterus has no receptor for this hormone.

Cholesystokinin is secreted from gastrointestinal system and is responsible for stimulating the digestion of protein and fat.

Whereas oxytocin plays a major role in the childbirth, sexual reproduction and social bonding.

External ear structure that helps to localize the direction from which sound arises

Step2247 [10]

The external ear structure is called the Pinna.

The Pinna helps to channel sound waves into the ear.

Many animals have the ability to move their pinna towards the direction of sound.

I have attached an image of a dog's ear to show you the external structure called the Pinna.

I hope this helps! I'm happy to answer any other questions you might have :)
