Hi everyone. Here's our next question identify the hormone that is correctly paired with its action. So three of these are going to be um not correct answers here. So let's take a look at them. Choice A. Says lutin. Izing hormone stimulates uterine contractions during childbirth. That is not correct neutralizing hormone as we recall uh stimulates the release of an egg from the ovary, stimulates ovulation. It also um stimulates the synthesis of testosterone. So choice A. Is not a correct pairing. Choice B says vasopressin increases water reabsorption by the kidneys. Well that is correct. So we will highlight that but to be thorough we'll keep on going and look at our other answers. Choice sees his growth hormone regulation of glucose levels but as indicated by its name, growth hormone stimulates growth. So Choice C. Is not correct. And finally, Choice D. Estrogen regulates the development and maintenance of male sexual characteristics. Well that is not correct. Estrogen regulates development maintenance of female sexual characteristics. So choice D. Incorrect. Also, so our answer here is be vasopressin increasing water reabsorption by the kidneys. See you in the next video
