In research on aging (both cellular aging and organismal aging), it has been found that aged cells do not progress through the cell cycle as they had previously. which of the following, if found in cells or organisms as they age, would provide evidence that this is related to cell signaling?

Growth factor ligands do not bind as effectively or efficiently to receptor

Explanation:

Cell signaling is a process of communication within the cells in the body or we can say it is the process of communication within and outside of the cell in the body. It is a wide network within the body. With the help of cell signaling, the cells communicate with the large or multi-cellular organism. Cell signaling occurs from different regions of the body but the main purpose of the cell signaling is to communicate with another cell in the body. There are different types of cells present in the body such as muscles cell that help a person in movement. There are other cells that are also present named immune cells that protect our body from outer antigens and boost up our new cells.
