Answer:
Red blood cells (RBC)
Answer:
the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science
2. they don't fit in our mouths so are a trait from when we had larger jaws
3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)
4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would
5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
Explanation:
Researchers may be able to induce adult cells to behave like embryonic stem cells an important advance in stem cell therapy.
Embryonic stem cells :
Embryonic stem cells are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4th to 7th day after fertilization. In normal embryonic development, they disappear after the 7th day, and begin to form the three embryonic tissue layers.
How embryonic stem cells are obtained?
Stem cells are now being collected from human embryos. In most cases, the embryos that are used have been aborted or left over from in vitro fertilization procedures. Although not technically feasible at this time, researchers expect that it is possible to clone stem cells from a patient's own somatic cells.
Cell therapy :
Cellular therapy (CT) is the transplantation of human cells to replace or repair damaged tissue and/or cells. With new technologies, innovative products, and limitless imagination, many different types of cells may be used as part of a therapy or treatment for a variety of diseases and conditions.

3D models are better than diagrams cause a diagram is flat, and its on a piece of paper, on the other hand 3D models have 3 Dimensions which show the model in a different view, they are also sometimes on paper but you have a better view if the model which helps you get more information of the diagram.
Hope I helped ya!! And plz put it under the right subject next time. This should go under Math.
