1. True or false: The largest big cat species to ever live is believed to be the saber-toothed tiger. True. According to estimates the saber-toothed tiger could have weighed up to 880 pounds (400 kilograms) and measured more than 7.2 feet (2.2 meters) in length, making it the largest...
How big are epithelial cells? What are nonsquamous epithelial cells? What is an epithelial cell? How do you distinguish between epithelial cells and connective tissue? What are the types of epithelial cells? What is the function of simple columnar epithelial cells?
Cell #2 is a pretty spectacular promyelocyte. It’s huge, it’s got tons of dark granules, and no specific granulation. It does have the beginnings of a little “hof” (a clear zone next to the nucleus) but that should not be confused with specific granulation. Cell #3 is pretty cl...

aNearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitohondrial DNA or mtDNA). 几乎每个细胞在人的身体有同样脱氧核糖...
Later, the XX bivalent was gradually displaced to the periphery of the nucleus, forming an electron-dense sex body by the end of the mid pachytene stage as is typical for mammalian males. The XX sex chromosomes of E. talpinus and E. tancrei males underwent a partial synapsis between the...
During formation, the RBC eventually loses its nucleus and leaves the bone marrow as a reticulocyte. At this point, the reticulocyte contains some remnants of organelles. Eventually these organelles leave the cell and a mature erythrocyte is formed. RBCs last an average of 120 days in the bloods...
