Can u take a pic of the questions?
Answer:
Complex is the right answer
Red blood cells transport oxygen throughout the body platelets aid in blood clotting and white blood cells help destroy and remove old cells and foreign substances. This is an example of how cells origin from the same cell (hematopoietic cell in the bone marrow) and then differentiate.
Hematopoietic stem cells are blood-forming stem cells. During hematopoiesis the hematopoietic stem cell divides via mitosis. As a result of mitosis, one daughter cell remains in the bone marrow to continue renewing the hematopoietic stem cells pool while the other goes through next stages of development. Maturate blood cell (red, white or platelet) to leave the bone marrow and enters the circulation.
I believe the answer is C, Leeunwenhoek because Copernicus was an astronomer, Kepler was a mathematician and astronomer and I THINK Bacon was a philosopher. Out of the 4, Leeuwenhoek was the only one strictly known for being a microbiologist, not only that but he was the first. I hope this helped :)
