Hello everyone and welcome to today's video. So we have that the internal program of events and sequence of morphological changes by which a cell commits suicide. And this is the important part of the question is collectively called. So now were given a certain number of processes that could describe this. Let's begin by answer choice D psychokinesis. And I want you to remember about mitosis and psychokinesis is the process that follows mitosis in which the methodic cell is going to be divided into the two daughter cells. Now, psychokinesis does not lead to a cell committing suicide. So we're going to cancel this out and then we have to go psychosis and disease a process by which cells called oocytes ingest other cells such as bacteria in order to for example launch defense in eukaryotic organisms against bacteria. So this is not going to be a cell committed suicide. So we're going to cancel this out. Then we have necrosis and this is tissue death and these can happen due to many things such as not enough nutrients flowing into the tissues. However, again this is not a cell committing suicide. So we're also going to cancel this out. And this all lifts us with apoptosis. I want you to recall from previous videos what apoptosis is and the process can be called programmed cell death. And what this means is that it's a process that the cell follows in order to commit suicide because of many different reasons. So we're going to we're going to highlight answer choice a apoptosis because it correctly describes what the question is talking about. So this is going to be the final answer to our question, and I really hope this video helped.
