Answer:
Totipotential.
Explanation:
There are different cell potencies. A <u>totipotent</u> cell is a stem cell that can divide itself and <u>differentiate in any cell </u>that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.
Because whales live in the ocean, many people think they are fish. But do you know that whales and dolphins are not fish? They are mammals. People are mammals too. Mammals are the group of animals that breath air using lungs, give birth to live young (rather than laying eggs), and feed their young with mother’s milk. All animals, including people, need oxygen, a chemical found in the air and in water. Fish use their gills to take oxygen from the water that they live in. But people get the oxygen we need by breathing air, using our lungs. Whales and dolphins use their lungs to breathe air also.
That’s one reasons why they come to the surface of the ocean. Sometimes they lie right at the surface of the water, with just a part of their back sticking out. Look closely at a picture of a whale or dolphin; can you see a nose on the whale? You can’t, because whales don’t have noses like you and me. Instead they have a hole – called a “blow hole” – on top of their heads. Sometimes when a whale breathes air out of its blow hole, it shows up as a spray or mist – called a “spout” – that can be seen many miles away. Blow holes are surrounded by muscles that keep the hole closed when the whale or dolphin is under water and open it when the animal is at the surface and needs to breathe.
In fact, some of the animals have two blow holes next to each other and others have only one. So when you see a picture of a whale, see if you can tell the difference. Pilot whales and dolphins have one blow hole; humpbacks, minkes and right whales have two
