Hello!
Let's solve this!
Convergent evolution is when two similar species (or some part of the species) have evolved through different branches but that fulfill the same function. In the case of marsupials, they are placental mammals that live in Australia. But they are different from placental mammals that live in South America.
The answer is Grass and Cactus. It will never stop running out of energy to feed the herbivore consumers.
Embryonic stem cells. These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body.
