Stem cells are cells of the body that can divide and become differentiated. stem cells specialise and take specific functions when an organism grows
mature tissues such as muscle, blood, tissue, bone, nerves, liver all have different types of cells.
they come from three to five day old embryo cells.
they represent potential in the regeneration and repair of damaged tissue. some therapies actually currently use stem cells for this reason

Answer: b. fossil fuels are nonrenewable, so humans will run out of them eventually. burning fossil fuels also contributes to global climate change by releasing carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are limited and we will run out of them eventually. They cannot be replenished in a single human's lifespan. Fossil fuels contribute to the destruction of ecosystems, but not only that. They release carbon dioxide into the atmosphere that warms the Earth. Therefore, anything other than B. would be incorrect.
