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.

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !

no, dan should reduce his discretionary spending. not long-term goals involve more planning than short-term goals do
