Hey, everyone. Let's take a look at this question together. This cellular change usually occurs where there is increased functional demand on a tissue or where there is hormonal stimulation. Is it answer choice? A hypertrophy? Answer choice B atrophy, answer choice C dysplasia or answer choice D neoplasia. Let's work this problem out together to try to figure out which of the following answer choices best describes this cellular change. So in order to solve this question, we have to recall what each of the following answer choices refers to, to determine which refers to a cellular change that occurs when there is increased functional demand on a tissue or where there is hormonal stimulation. And we know that that increased functional demand on a tissue refers to an increase in the tissue or organ size due to an increase in cell size of which that increase in the tissue or organ size due to the increase in cell size occurs without an increase in cell number. And we know that the correct term for the cellular change is answer choice. A hypertrophy which is the correct answer. And all other answer choices are incorrect since hypertrophy is an increase in the tissue or organ size due to an increase in cell size without an increase in cell number. So answer choice A is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
