You can see if their is a heart beat.
1. It composes of cell; if no cell, no life. 2. Organization- both on a molecular and cellular level. 3. Metabolism- all living organisms must use energy of some sort. 4. Response to Stimuli- simple or complex actions in response to environment. 5. Reproduction- living things must be able to reproduce, not for the individual, but for the continuation of life. 6. Growth- not all organisms must grow or develop, through cell enlargement or replication, but it is common in most living things.
I think that to know something is alive, it has to have cells. Also, all living things reproduce. So if it is a plant, animal, or anything else that has cells or reproduces, it is alive. Objects such as paper, clothes, or anything like that are not alive.
I think you know when something is alive because it can grow and change (this would be what I would look for first). It would also have to be made out of cells, not adams. You can also tell because they have to be able to make another of themselves, like a binder cant make another binder.
If its Breathing, has a beating heart, blood pumping ect.
You know if something is alive if it has cells because every living thing has cells
Well if your plant has got brown and curled up you put water and sun light and all its other needs. And in a week or so come and check if the plant has made progress then it is alive!
You know that something is alive when it reacts to a stimulus . Wether it is a Venus Fly Trap or a human it will react.For example a human might jump ir yell if you touch them just like how a Venus Fly Trap that would close all living things react to a stimulus.
you know when something is alvie when you see it moving or when you listen to its heart and you hear it.
tHINGS ARE ALIVE IF THEY MOVE.
All livng things have cells
All lvings things have DNA
All livng things have the ability to reproduce
Crystal,
Do all living things have hearts?
Do all living things have blood? Do all living things breath?
All living things move.
They reposnd to change
All thing are alive if they have cell.
All living things have DNA.
All living things are alive if the can grow or change.
Also all thing can reproduce if they are alive.
you know if it is living if it moves, has cells, has DNA and has the ability to reproduce.
You will know if something is alive if it responds to change.
You can tell if it can move or breathe. A single cell is alive because it has energy and can divide or reproduce.
I know that something is alive if it has a heart that beats,if it moves, if it can breath, and if it has multiple cells.
Mrs. D,
no, not every living thing has a heart
You know if it’s alive if its making any movement or breathing in any way.
You can tell by if its moving or having a beating heart
You can tell if something is alive if it moves,has DNA,or has cells.
all living things have cells,dna, and able to reproduce.
How do you know something is alive? You know something is alive if it is moving, breathing, it reproduces, has cells, and goes through a process
if its moving, DNA, growth and development, metabolism, homeostatis, breathing, organisaziaton, heart pumping, blood circulating
you know if something is alive if it has DNA and cells
If its breathing and the heart is pumping.
you can tell if something is living if it has a heart and it is beating or if it has cells
All living things have DNA. All living things have cells. All living things have the ability to reproduce. All living things respond to change.
If it moves or goes through photosintisis
Because it’s moving,and its breathing.
Its has to breath.
If its still breathing.
You could tell if someone’s alive if it’s either you can feel its heart beating or if you see it moving.
You know somethings alive if they have DNA, if there Breathing, Or If they move. =D
You know something is living if it has DNA and if it has cells. It is also living if it has the ability to reproduce.
You know if something is alive if it is made of cells, has DNA, and moves. Plants also move so they can get more sunlight. People that are alive move.
If It Is Breathing Or Has A Pulse.
ALL LIVING THINGS HAVE CELLS HEARTS AND THEY HAVE DNA AND THEY CAN REPROUCDE.
WHEN YOU SEE THE HEART MOVE THAT LET YOU KNOW THAT IS’T BREATHING AND PUMPING BLOOD.

Someone in my class made an epigram when the teacher asked him a question.
if it has blood and breathes and has dna
if it has blood or dna
I think if it moves its alive.
You can tell if something is alive if it is moving, has cells, or see if it has DNA.
If it has a pulse.
If it isn’t dry inside
all living things have cells and dna
You know something is alive if it has a beating hart, if it is moving, and if it is breathing.
