Welcome back. Let's look at the next question. Which of the following conditions must be met by an entity discovered on another planet in order to confirm the existence of life. Well to be defined as alive there's certain characteristics um that we use to define that um They are that it consists of cells that it's capable of replicating itself, that it can store genetic information for the passing on of that in replication that it can acquire and use energy and that can evolve. So let's look at our answer choices and we see that choice A says um first we should look over them all and we see that choice D. Is all of the above. So again, always good to look over that at first to see that there's a possibility that more than one answer is correct. So Choice A. Says it should be cellular and capable of replicating and processing information. Will we see that? Yes, capable of replicating itself and consisting of cells are two of those characteristics of life. So Choice A is correct. We're just gonna put a dot rather than selecting it right away since we know we can have more than one correct answer. Choice B says it must acquire and utilize energy. Yes, that is a characteristic of life. So also correct. And if I wanna test if time were of the essence, I'd go ahead and pick all of the above since I already have one more than one correct answer. But in the interest of being thorough let's look at choice see it should have evolving populations and yes, that's another characteristic of life. So see also correct and therefore are correct answer choices D All of the above. So to uh, to confirm the existence of life on another planet, um, all of these choice D All of the above. There are all conditions that must be met. See you in the next video.
