How can scientists tell if the cells aren’t alive anymore?

Answers

Answer 1

There are many ways that a scientist can tell if cells aren’t alive anymore.

One example of this is by figuring out if a cells membrane has been damaged- cells with damaged membranes are usually considered dead because the membrane is key for the cells survival.

They usually find this out by using a cell-impermeant DNA binding dye like propidium iodide. If the membrane is intact then the dye can’t enter the cell because the membrane will act like a barrier. A damaged membrane will allow the dye to get through, proving that the cell is dead.

Hope this helps to some degree :)

Amnesia refers to the loss of memories, such as facts, information and experiences. Though forgetting your identity is a common plot device in movies and television, that's not generally the case in real-life amnesia. Instead, people with amnesia — also called amnestic syndrome — usually know who they are. But, they may have trouble learning new information and forming new memories.
